Haasiella

Haasiella is a fungal genus in the family Hygrophoraceae.^[4] It is a monotypic genus that contains only the species Haasiella venustissima.^[1] Haasiella splendidissima, formerly considered to be a distinct species based on its 4-spored basidia, was found by a DNA study to be synonymous with Haasiella venustissima.^[1] Haasiella venustissima is only known from Europe and is saprotrophic on wood.^[1][5] Haasiella was described as a new genus in 1966 by Czech mycologists František Kotlaba and Zdeněk Pouzar.^[6] It is most closely related to the genus Hygrophorus.^[1]
