The pale brittle stem mushroom, Psathyrella candolleana, a species new to Iraq, is described from the sub-arid region of Aljazira (Iraq). Both classical taxonomy and DNA analyses confirm the identification of the fungus strain (RM-0861) as P. candolleana, a species that belongs to the family Psatherellaceae known to possess medicinal properties. Being a saprophyte, this fungus is cultivatable in laboratory conditions and therefore shows potential for production and use as a medicinal mushroom in human and veterinary health.
A checklist is presented concerning the species composition of Hymenomycetes (Aphyllophorales s.l.) and Heterobasidiomycetes in Israel based on data of previous studies and field sample collections. In total, 242 species are presented, of which five are new records for the Israeli mycobiota, namely Australohydnum dregeanum, Ceriporiopsis consobrina, C. resinascens, Fibroporia vaillantii, and Postia inocybe. The distribution and habitat of each species in Israel are also summarized. This checklist will serve as valuable data for future species diversity studies of these fungi in Israel.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
