Bioactive Secondary Metabolites from Fungi of the Genus Cytospora Ehrenb. (Ascomycota).

Cytospora is a genus of fungi belonging to the Cytosporaceae family (Sordariomycetes, Ascomycota) considered as a prolific source of specialized metabolites due to their ability to produce diverse secondary metabolites with a broad range of biological activities. Since the first chemical investigation of this genus in the 1980s, further studies have led to the isolation and structural elucidation of several bioactive compounds including cytosporones, nonanolides, macrocyclic dilactones, and terpenoids. This review summarizes, for the first time, the chemical diversity of bioactive secondary metabolites from the genus Cytospora and highlights its potential as an alternative source of secondary metabolites for pharmacological studies. Moreover, this review will serve as a basis for future investigations of compounds of this genus.

Diversity of Edible and Medicinal Mushrooms Used in the Noun Division of the West Region of Cameroon.

This article presents discussions of mushrooms as a source of food, income, as well as medicine among the Bamoun people of the highlands of West Cameroon, where the vegetation is mainly savannah mixed with forest galleries. Like most tribes in tropical Africa, the Bamoun people use a wide range of natural products as mushrooms. This study attempts to identify the various mushrooms exploited by the Bamoun. Ethnomycological surveys and field trips were conducted over 4 years in several villages in the Noun Division. Samples of wild mushrooms were collected from both the savannah and the forest galleries. These were described, preserved, and identified. The study shows that the Bamoun people use at least 40 species of mushrooms for either food or medicine. These species belong to 8 genera: Auricularia, Cantharellus, Ganoderma, Pleurotus, Lactarius, Lactifluus, Russula, and Termitomyces. Species of genera Lactarius, Lactifluus, Russula, and Termitomyces are most often used for food, whereas Ganoderma spp. and Pleurotus tuber-regium are mainly exploited for medicinal purposes. This survey provides an overview of the diversity of mushrooms and their importance to the local people of this area. Since some of the species mentioned by the local population were not fruiting at the time of our field trips, additional investigations are needed to further clarify the diversity and the usage of mushrooms in this region.
