A new species of Hygrophorus, H. yadigarii sp. nov. (Hygrophoraceae), with an isolated systematic position within the genus from the Colchic part of Turkey

Hygrophorus yadigarii (Hygrophoraceae/Basidiomycota) is described as a new species for science based on basidiomata collected from Maçka, Trabzon, Turkey. The new taxon is quite different even from the closest relatives, easily distinguished by the other species because of its grayish to ash-colored, gregarious to subcaespitose, sticky basidioma.
