RESUMO
Abstract Xylobotrum portentosum (Mont.) Pat. is a striking Neotropical fungal species but it has been reported only a few times from Southern Brazil (States of Paraná and Santa Catarina), found in remnants of Atlantic Forest. Herein we report the species for the first time from the Southeastern Region of Brazil (State of São Paulo). A brief description and color photographs of the fresh specimen are presented.
Resumo Xylobotrum portentosum (Mont.) Pat. é uma espécie notável de fungo neotropical que foi registrada apenas poucas vezes para a Região Sul do Brasil (Paraná e Santa Catarina), encontrada em remanescentes de Mata Atlântica. Neste trabalho a espécie é reportada pela primeira vez para a Região Sudeste do Brasil (Estado de São Paulo). São apresentadas uma breve descrição e fotografias coloridas do espécime fresco.
RESUMO
A combined dataset of rDNA ITS and LSU sequences was used to infer the phylogenetic relationships of Hydnochaete peroxydata (≡ Hydnum peroxydatum), the type species of Hydnochaete. The species was retrieved nested within the Hymenochaete s. str. clade; therefore Hydnochaete is regarded as a synonym of Hymenochaete and the new combination Hymenochaete peroxydata is proposed.

Genus Coltricia is re-evaluated in Brazil and 10 species are accepted, namely C. barbata, C. cinnamomea, C. duportii, C. focicola, C. globispora, C. hamata, C. montagnei, C. perennis, C. permollis and C. velutina. Coltricia focicola and C. montagnei are reported respectively for the first time from South America and Brazil. Coltricia permollis and C. velutina are described as new species. Description of the new species, illustrations and a key to species of Coltricia known from the Neotropics are provided. The current knowledge of the genus in Brazil is discussed.
