Trichosporon Asahii fungaemia in an immunocompetent polytrauma patient who received multiple antibiotics.

Trichosporon asahii is a yeast-like fungus that is emerging as an important cause of invasive infections in tertiary medical centres. A 58-year-old Chinese man with no known medical illnesses presented with liver lacerations and multiple fractures following an alleged 12-foot fall at a construction site. The gravity of his injuries and poor haemodynamic status necessitated an intensive care unit (ICU) admission, during which several febrile episodes were detected and multiple antibiotics were administered. After being in the ICU for at least two weeks, a urease-positive yeast was isolated from the patient's blood. The yeast formed dry, fuzzy and wrinkled white colonies on Sabouraud dextrose agar following prolonged incubation, and produced blastoconidia, true hyphae, pseudohyphae and arthroconidia on slide culture. It was identified biochemically by the ID 32 C kit as T. asahii. The yeast had elevated minimal inhibitory concentration (MIC) values to fluconazole, amphotericin B, flucytosine and all echinocandins tested. In view of this, the patient was treated with voriconazole and was successfully transferred to the general medical ward.

Endophytic fungi from the branches of Camellia taliensis (W. W. Smith) Melchior, a widely distributed wild tea plant.

Camellia taliensis (W. W. Smith) Melchior is a wild tea plant endemic from the west and southwest of Yunnan province of China to the north of Myanmar and is used commonly to produce tea by the local people of its growing areas. Its chemical constituents are closely related to those of C. sinensis var. assamica, a widely cultivated tea plant. In this study, the α diversity and phylogeny of endophytic fungi in the branches of C. taliensis were explored for the first time. A total of 160 fungal strains were obtained and grouped into 42 species from 29 genera, which were identified based on rDNA internal transcribed spacer sequence analysis. Diversity analysis showed that the endophytic fungal community of the branches of C. taliensis had high species richness S (42), Margalef index D' (8.0785), Shannon-Wiener index H' (2.8494), Simpson diversity index DS (0.8891), PIE index (0.8947) and evenness Pielou index J (0.7623) but a low dominant index λ (0.1109). By contrast, that in the branches of C. taliensis had abundant species and high species evenness. Diaporthe tectonigena, Acrocalymma sp. and Colletotrichum magnisporum were the dominant endophytic fungi. The phylogenetic tree was established by maximum parsimony analysis, and the 11 orders observed for endophytic fungi belonging to Ascomycota and Basidiomycota were grouped into 4 classes.

Occurrence of oleaginous yeast from mangrove forest in Thailand.

A total of 191 yeasts were isolated from 197 samples collected from eight estuarine mangrove forests along four different coastlines of Thailand (Andaman Sea and the East, North and West coasts of the Gulf of Thailand). Of these, 178 isolates were identified as 32 species in 16 genera of Ascomycota, 12 species in nine genera of Basidiomycota, and 13 isolates as potential new species, respectively. Mangroves located along the Andaman Sea coastline had a higher yeast diversity at the species and genera levels than those along the Gulf of Thailand. Kluyveromyces siamensis was the most frequently isolated species, whilst Candida tropicalis was the only species isolated at all eight sites. Screening isolated yeast strains belonging to genera previously reported as oleaginous yeast plus the 13 potential new species, revealed two oleaginous strains, Rhodotorula sphaerocarpa 11-14.4 and Saitozyma podzolica 11-11.3.1. Both of these strains were isolated from the same mangrove forest on the Andaman Sea coastline. They could accumulate lipid when suspended in glucose solution without any supplementation, while the fatty acid composition and oil profile of Rh. sphaerocarpa 11-14.4 and Sait. podzolica 11-11.3.1 were similar to vegetable oil and cocoa butter, respectively.

The new species Puccinia telimutans causes Mexican potato rust disease of wild potatoes and shows a unique telial metamorphosis.

Puccinia telimutans is described as a new species of rust fungi (Basidiomycota, Pucciniales) and causal agent of Mexican potato rust disease of the endemic wild potatoes Solanum demissum and S. verrucosum from Mexico. It is microcyclic and produces telia that show a unique succession of one-celled, catenulate teliospores that germinate upon maturity, followed by resting teliospores that are pedicellate and two-celled. Puccinia telimutans appears to be restricted to Mexico and has formerly been confused with P. pittieriana, which causes common potato rust in South America.

Anti-tumour Effect and Pharmacokinetics of an Active Ingredient Isolated from Inonotus hispidus.

Inonotus hispidus is an anti-tumour drug used in folk medicine. (4S,5S)-4-Hydroxy-3,5-dimethoxycyclohex-2-enone (HDE) is a compound isolated from Inonotus hispidus for the first time. However, the mechanisms underlying its therapeutic effects have not been elucidated. In this study, the in vitro screening, in vivo anti-tumour effects, mechanism of action, pharmacokinetics, and tissue distribution of HDE were investigated. HDE could inhibit the proliferation of HepG2 cells. Additionally, its half-maximal inhibitory concentration was 7.9 µg/mL. Increasing HDE concentrations significantly increased apoptosis rate in a dose-dependent manner. Furthermore, HDE was rapidly absorbed into mouse plasma, reaching a maximum concentration at 30 min. The area under the plasma HDE concentration-time curves for the studied organs were as follows: spleen > liver > lung > kidney > muscle > thymus > heart > brain. HDE also inhibited tumour growth up to 69%. The weights of organs harvested from HDE-treated mice were not significantly different from those harvested from control mice. Furthermore, HDE upregulated Fas expression and downregulated FasL expression in HepG2 cells. HDE significantly increased caspase-3 and caspase-8 activity. The anti-tumour effect of HDE might be realized by activating the Fas-mediated apoptotic pathway. We also found that HDE undergoes enterohepatic circulation or is quickly absorbed by the body, and the drug is released back into systemic circulation. In conclusion, HDE significantly inhibited H22 hepatocarcinoma cells (H22)tumour growth in mice without damaging organs; therefore, it may be suitable for treating liver cancer.

Characterization of Biological Activities of Methanol Extract of Fuscoporia torulosa (Basidiomycetes) from Italy.

This work investigated the antiradical, antibacterial, and antifungal properties of a methanol extract from Fuscoporia torulosa (PeruMyc1834) fruit body from Central Italy. The ITS partial sequence of the F. torulosa strain matched at a 100% rate those of various strains belonging to the species. Two complementary test systems, namely α,α-diphenyl-ß-picrylhydrazyl (DPPH) radical scavenging and ß-carotene/linoleic acid systems, were used. Free radical scavenging, measured by DPPH assay on methanol extract, showed an activity of 38.17 ± 2.74% of Trolox activity. The methanol extract of F. torulosa inhibited the growth of Gram-positive bacteria, particularly those belonging to the genus Bacillus (i.e., B. subtilis and B. cereus), better than Gram-negative bacteria. All the fungal isolates used in the present study for antifungal activity inhibited their growth when a concentration of 2.27 mg mL-1 of methanol extract was used (minimum inhibitory concentration from < 0.28 to 2.27 mg mL-1). This study established that the extracted antioxidant and antimicrobial compounds produced by F. torulosa can be exploited in treating diseases that affect humans, plants, and animals. There is a need to carry out further study to establish the chemical composition of the methanol extract.

Chemical Profile, In Vitro Enzyme Inhibitory, and Antioxidant Properties of Stereum Species (Agaricomycetes) from Turkey.

Recently, mushroom species have been the focus of researchers' interest because of several bioactivities. The aim of this study was to investigate the chemical profile and biological activities of various extracts of two Stereum species (S. rugosum and S. sanguinolentum). Antioxidant activity was tested using ß-carotene-linoleic acid, DPPH scavenging, ABTS·+ scavenging, cupric-reducing antioxidant capacity (CUPRAC), and metal chelating assays. The extracts were also tested for their enzyme inhibitory activities against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). HPLC-DAD was applied for the analysis of phenolic compounds, and fatty acid compositions were determined using GC and GC-MS. When fumaric acid and catechin hydrate were found as the most abundant phenolic compounds in both Stereum species, oleic acid and palmitic acid were identified as major fatty acids. Both of the studied Stereum methanol extracts were determined as the most active in ß-carotene-linoleic acid, DPPR, ABTS·+, and CUPRAC assays; the n-hexane extracts were found to be most active in metal chelating and AChE inhibitory activity assays. In addition, the methanol extract of S. sanguinolentum (IC50: 34.26 ± 0.31 µg/mL) showed higher ABTS·+ scavenging activity than α-tocopherol (IC50: 38.51 ± 0.54 µg/mL). The acetone extracts were found as potent inhibitors against BChE. These results suggest that Stereum species could be an antioxidant source and cholinesterase agent in pharmaceutic, food, and cosmetics industries.

Employment of ARTP to Generate Phellinus baumii (Agaricomycetes) Strain with High Flavonoids Production and Validation by Liquid Fermentation.

To obtain Phellinus baumii strain with high flavonoids yield, ARTP was employed to generate mutants of a Ph. baumii strain, which were screened for higher flavonoids content. After five rounds of screening, four mutants were identified to produce more flavonoids than the wild type strain under optimal conditions, of which A67 was the mutant with the highest flavonoids productive capacity. When cultured in shake flasks, the maximum intracellular total flavonoids production of A67 reached 0.56 g/L, 86.67% higher than the total flavonoids in CK. Antagonistic testing, RAPD, and HPLC analysis suggested that ARTP caused changes of the genetic material and metabolites in Ph. baumii. In addition, the superiority of A67 to CK was proved by liquid fermentation using unstructured kinetic models, which was performed in a 50-L fermentor. The maximum intracellular total flavonoids production and dry mycelium weight of A67 reached 0.64 g/L and 15.24 g/L, which was an increase of 88.24% and 18.23% compared with CK, respectively. This work could provide an efficient and practical strategy to obtain high flavonoids production strains and the superiority of A67 could also provide a reference to further increase flavonoids production of Ph. baumii in large-scale production mode by submerged fermentation process.

The species of Coleosporium (Pucciniales) on Solidago in North America.

Species of Coleosporium (Pucciniales) are rust fungi that typically alternate between pines and angiosperms. In North America, species of Coleosporium often infect Solidago (goldenrods), although their taxonomy on these hosts is unresolved. Joseph. C. Arthur and George B. Cummins regarded these as a single species, Coleosporium solidaginis (fide Arthur) or C. asterum (fide Cummins), but later inoculation studies demonstrated the presence of more than one species, distinguishable by their aecial hosts. A more recent taxonomic study of Coleosporium found that specimens on Solidago identified as C. asterum in North America were not conspecific with the type, which is from Japan, prompting the present study. Herein, we conducted a systematic study on ca. 60 collections of Coleosporium infecting species of Asteraceae from North America using regions of ribosomal DNA and morphology of teliospores and basidia. Our data indicate at least three species of Coleosporium occur on Solidago in North America, C. solidaginis, C. montanum comb. nov., which is proposed for the taxon that has commonly been identified as C. asterum in North America, and C. delicatulum, all of which can be differentiated by morphology of their basidia. In addition, the challenges of marker selection for molecular barcoding of rust fungi is discussed.

Biodegradation of asphaltene and petroleum compounds by a highly potent Daedaleopsis sp.

Petroleum, as the major energy source, is indispensable from our lives. Presence of compounds resistant to degradation can pose risks for human health and environment. Basidiomycetes have been considered as powerful candidates in biodegradation of petroleum compounds via secreting ligninolytic enzymes. In this study a wood-decaying fungus was isolated by significant degradation ability that was identified as Daedaleopsis sp. by morphological and molecular identification methods. According to GC/MS studies, incubation of heavy crude oil with Daedaleopsis sp. resulted in increased amounts of C24 compounds. Degradation of asphaltene, anthracene, and dibenzofuran by the identified fungal strain was determined to evaluate its potential in biodegradation. After 14 days of incubation, Daedaleopsis sp. could degrade 93.7% and 91.2% of anthracene and dibenzofuran, respectively, in pH 5 and 40 °C in optimized medium, as revealed by GC/FID. Notably, analysis of saturates, aromatics, resins, and asphaltenes showed a reduction of 88.7% and 38% in asphaletene and aromatic fractions. Laccase, lignin peroxidase, and manganese peroxidase activities were enhanced from 51.3, 145.2, 214.5 U ml-1 in the absence to 121.5, 231.4, and 352.5 U ml-1 in the presence of heavy crude oil, respectively. This is the first report that Daedaleopsis sp. can degrade asphaltene and dibenzofuran. Moreover, compared to the reported results of asphaltene biodegradation, this strain was the most successful. Thus, Daedaleopsis sp. could be a promising candidate for biotransformation of heavy crude oil and biodegradation of recalcitrant toxic compounds.

Host-specificity of symbiotic mycorrhizal fungi for enhancing seed germination, protocorm formation and seedling development of over-collected medicinal orchid, Dendrobium devonianum.

All orchids maintain an obligate relationship with mycorrhizal symbionts during seed germination. In most cases, germination-enhancing fungi have been isolated from roots of mature plants for conservation and cultivation purposes. To understand the germination biology of Dendrobium devonianum, an over-collected medicinal orchid, the seeds of D. devonianum were inoculated with a fungal strain (FDd1) isolated from naturally occurring protocorms of D. devonianum and two other germination-enhancing fungal strains (FDaI7 and FCb4) from D. aphyllum and Cymbidium mannii, respectively. The fungal strain was isolated from five protocorms of D. devonianum and identified as a species of the genus Epulorhiza. In germination trials, treatments with all of the three fungal strains showed a significant promoting effect on seed germination and protocorm formation, compared with the control treatment (no inoculation). However, FDd1 fungal strain showed the greatest effectiveness followed by FDaI7 and FCb4. For all inoculation and control treatments, seeds developed to protocorms regardless of the presence of illumination, whereas protocorms did not develop to seedlings unless illumination was provided. The results of our manipulative experiments confirmed the hypothesis that mycorrhizae associated with orchid seedlings are highly host-specific, and the degree of specificity may be life stagespecific under in vitro conditions. The specific mycorrhizal symbionts from protocorms can enhance restoration efforts and the conservation of orchids such as D. devonianum.

Screening of Bioactive Compounds of Medicinal Mushrooms Collected on Tunisian Territory.

This study is, to our knowledge, the first to investigate the pharmacological importance of wild Tunisian mushrooms. Ethanolic extracts of 5 Tunisian mushrooms-Phellinus torulosus, Fomes fomentarius, Trametes versicolor, Pisolithus albus, and Fomitopsis pinicola-were collected from the Kroumirie Region (North Tunisia). The dry basidomes of mushrooms were extracted using ethanol and evaluated for total polyphenol, flavonoid, flavonol, tannin, proanthocyanidin, and anthocyanin content. In addition, their antioxidant activities were determined using 3 assays (testing 2,2-diphenyl-1-picrylhydrazyl [DPPH] radical scavenging, the reducing power of iron, and the iron-chelating power). Their antimicrobial activities were assessed against 8 bacterial species. The results revealed the presence of significant differences between the secondary metabolites and biological activities of the different tested extracts. In addition, significant correlations were observed between antioxidant activities and phenolic contents. Crude ethanol extracts prepared from basidomes of F. fomentarius and Ph. torulosus have higher total phenolic content and antioxidant activity per the DPPH and metal-chelating activity assays. The reducing power assay showed that the ethanolic extract of F. pinicola had the highest activity. Ethanolic extracts of the 5 mushrooms have antibacterial activity against the evaluated strains.

Evaluation and Characterization of Nutritive Properties of the Jelly Ear Culinary-Medicinal Mushroom Auricularia auricula-judae (Agaricomycetes) from Nigeria.

This study investigated the nutritive properties of the culinary-medicinal mushroom Auricularia auricula- judae. From the analysis, among the major minerals, potassium was found in the highest concentration, with a value of 172.03 ± 8.62 mg/kg, whereas manganese had the highest concentration among trace elements, with a value of 1.66 ± 0.11 mg/kg. Glutamic acid was the amino acid detected in the largest amounts in this study, with a value of 10.09 ± 1.86 mg/kg. Although glutamine and asparagine were not detected in this mushroom, cysteine and methionine had the lowest concentrations, with values of 0.34 ± 0.01 and 0.80 ± 0.03 mg/kg, respectively. The predominant oil was 9,12-octadecadienoic acid (Z,Z)methyl ester, with retention times of 21.246 and 21.715 minutes, and comprising percentages of the total of 4.309 and 47.385, respectively.

Exploring the Antibacterial and Antifungal Potential of Jellyfish-Associated Marine Fungi by Cultivation-Dependent Approaches.

Fungi isolated from marine invertebrates are of considerable importance as new promising sources of unique secondary metabolites with significant biomedical potential. However, the cultivable fungal community harbored in jellyfish was less investigated. In this work, we seek to recover symbiotic fungi from different tissues of jellyfish Nemopilema nomurai. A total of seven morphotypes were isolated, which were assigned into four genera (Aspergillus, Cladosporium, Purpureocillium, and Tilletiopsis) from two phyla (Ascomycota and Basidiomycota) by comparing the rDNA-ITS sequences with the reference sequences in GenBank. The most fungi were found in the inner tissues of subumbrella. Two of the cultivation-independent procedures, changing media type and co-cultivation, were employed to maximize the complexity of metabolites. Thus, thirteen EtOAc gum were obtained and fingerprinted by High Performance Liquid Chromatography (HPLC) equipped with a photodiode array (PDA) detector. Antibacterial and antifungal activities of these complex mixtures were tested against a panel of bacterial and fungal pathogens. The antimicrobial results showed that all of the 13 EtOAc extracts displayed different levels of antibacterial activity, three of which exhibited strong to significant antibacterial activity to the bacterial pathogens Staphylococcus aureus and Salmonella entrica. Antifungal activity indicated that the EtOAc extracts from pure culture of Aspergillus versicolor and co-culture of A. versicolor and Tilletiopsis sp. in rice media were promising for searching new compounds, with the maximal mycelial growth inhibition of 82.32% ± 0.61% for Rhizoctonia solani and 48.41% ± 11.02% for Botrytis cinerea at 200 µg/ml, respectively. This study is the first report on the antibacterial and antifungal activity of jellyfish-associated fungi and allows the first sight into cultivable fungal community residing in jellyfish. Induced metabolites by cultivation-dependent approaches provides a new reservoir for drug discovery from jellyfish-derived fungi.

Integrated options for the management of black root rot of strawberry caused by Rhizoctonia solani Kuhn.

An investigation was made to manage strawberry black root rot caused by Rhizoctonia solani (R. solani) through the integration of Trichoderma harzianum (T. harzianum) isolate STA7, mustard oil cake and Provax 200. A series of preliminary experiments were conducted to select a virulent isolate of R. solani, an effective isolate of T. harzianum, a suitable organic amendment, and a suitable fungicide before setting the experiment for integration. The pathogenicity of the selected four isolates of R. solani was evaluated against strawberry and isolate SR1 was selected as the test pathogen due to its highest virulent (95.47% mortality) characteristics. Among the 20 isolates of T. harzianum, isolate STA7 showed maximum inhibition (71.97%) against the test pathogen (R. solani). Among the fungicides, Provax-200 was found to be more effective at lowest concentration (100 ppm) and highly compatible with Trichoderma isolates STA7. In the case of organic amendments, maximum inhibition (59.66%) of R. solani was obtained through mustard oil cake at the highest concentration (3%), which was significantly superior to other amendments. Minimum percentages of diseased roots were obtained with pathogen (R. solani)+Trichoderma+mustard oil cake+Provax-200 treatment, while the highest was observed with healthy seedlings with a pathogen-inoculated soil. In the case of leaf and fruit rot diseases, significantly lowest infected leaves as well as fruit rot were observed with a pathogen+Trichoderma+mustard oil cake+Provax-200 treatment in comparison with the control. A similar trend of high effectiveness was observed by the integration of Trichoderma, fungicide and organic amendments in controlling root rot and fruit diseases of strawberry. Single application of Trichoderma isolate STA7, Provax 200 or mustard oil cake did not show satisfactory performance in terms of disease-free plants, but when they were applied in combination, the number of healthy plants increased significantly. The result of the current study suggests the superiority of our integrated approach to control the sclerotia forming pathogen R. solani compared to the individual treatment either by an antagonist or by a fungicide or by mustard oil cake.

Diversity and biotransformative potential of endophytic fungi associated with the medicinal plant Kadsura angustifolia.

This study investigated the diversity and host component-transforming activity of endophytic fungi in medicinal plant Kadsura angustifolia. A total of 426 isolates obtained were grouped into 42 taxa belonging to Fungi Imperfecti (65.96%), Ascomycota (27.00%), Zygomycota (1.64%), Basidiomycota (0.47%) and Mycelia Sterilia (4.93%). The abundance, richness, and species composition of endophytic assemblages were significantly dependent on the tissue and the sampling site. Many phytopathogenic species associated with healthy K. angustifolia were found prevalent. Among them, Verticillium dahliae was dominant with 16.43% abundance. From 134 morphospecies selected, 39 showed remarkable biocatalytic activity and were further identified as species belonging to the genera Colletotrichum, Eupenicillium, Fusarium, Hypoxylon, Penicillium, Phomopsis, Trametes, Trichoderma, Umbelopsis, Verticillium and Xylaria on the basis of the sequence analysis of the internal transcribed spacer (ITS1-5.8S-ITS2). The results obtained in this work show that K. angustifolia is an interesting reservoir of pathogenic fungal species, and could be a community model for further ecological and evolutionary studies. Additionally, the converting potency screening of some endophytic fungi from this specific medicinal plant may provide an interesting niche on the search for novel biocatalysts.

The diversity and antimicrobial activity of endophytic fungi associated with medicinal plant Baccharis trimera (Asteraceae) from the Brazilian savannah.

The fungal endophyte community associated with Baccharis trimera, a Brazilian medicinal plant, was characterized and screened for its ability to present antimicrobial activity. By using molecular methods, we identified and classified the endophytic fungi obtained into 25 different taxa from the phyla Ascomycota and Basidiomycota. The most abundant species were closely related to Diaporthe phaseolorum, Pestalotiopsis sp. 1, and Preussia pseudominima. The differences observed in endophytic assemblages from different B. trimera specimens might be associated with their crude extract activities. Plants that had higher α-biodiversity were also those that contributed more to the regional (γ) diversity. All fungal isolates were cultured and their crude extracts screened to examine the antimicrobial activities. Twenty-three extracts (12.8%) displayed antimicrobial activities against at least one target microorganism. Among these extracts, those obtained from Epicoccum sp., Pestalotiopsis sp. 1, Cochliobolus lunatus, and Nigrospora sp. presented the best minimum inhibitory concentration values. Our results show that the endophytic fungal community associated with the medicinal plant B. trimera included few dominant bioactive taxa, which may represent sources of compounds with antifungal activity. Additionally, the discovery of these bioactive fungi in association with B. trimera suggests that Brazilian plants used as folk medicine may shelter a rich fungal diversity as well as taxa able to produce bioactive metabolites with antimicrobial activities.

Pectinolytic yeasts from viticultural and enological environments: novel finding of Filobasidium capsuligenum producing pectinases.

In this study indigenous yeasts associated with wineries, grapes and Malbec fermented must from San Rafael viticulture region (Argentina) were isolated to select pectinolytic strains for their potential use in enology. Pectinolytic yeasts were identified by physiological and molecular methods. Among 78 isolates, only nine were able to produce extracellular pectinases. Six isolated from berry surface were identified as Aureobasidium pullulans and the remaining isolates, recovered from wineries, belonged to Saccharomyces cerevisiae and Filobasidium capsuligenum species. Pectinase production was evaluated under vinification-related conditions: pH 3.5, 12 and 28 °C. A. pullulans U-12 produced the highest pectinolytic activity at low temperature (1.16 U ml(-1) ), while F. capsuligenum strains showed good activity at 12 and 28 °C (0.77 and 1.15 U ml(-1) , respectively) being this study the first report on the capacity of this species to produce pectinases. The pectinolytic activity of F. capsuligenum B-13 showed an optimum at pH 4.5 and two peaks at 20 and 50 °C. The enzyme half-life was 2 h at 40 °C and retained 65% of its activity at 40 °C after 1 h of incubation. This pectinolytic system displayed remarkable activity at pH and temperatures found in vinification, suggesting a potential candidate for applying to wine-making.

[Report of Quambalaria cyanescens associated with birch].

Long-term microbiological investigation of the pollen of silver birch (Betula pendula) in the Mos- cow, and Moscow region areas revealed that: almost one-third of the analyzed samples, contained the fungus identified by morphological, cultural, and molecular genetic techniques as Quambalaria cyanescens (de Hoog & G. A. de Vries) Z.W. de Beer, Begerow & R. Bauer. This species was previously known mostly as a syrmbiont of tropical plants of the generaEucalyptus and Cortyminbia and has not been isolated in Russia. We revealed a close association between Quambalaria cyanescens and silver birch. The micromycete was regulaly detected in pollen samples, as well as on the.inside and outside of the aments, on the surface of leaves and branches. It was never isolated from other plant species in the investigated area. The data on the morphological and cultural characteristics of the fungus, its cell ultrastructure, and occurrence are presented, as well as the phylogenetic analysis of the isolated strains.
