Microascus

Microascus is a genus of fungi in the family Microascaceae.

History
It was introduced by Luttrell (1951) to accommodate genus Microascus which was originally placed in family Ophiostomataceae (Nannfeldt 1932, ) or Eurotiaceae in Eunotiales order, (Moreau and Moreau 1953; Emmons and Dodge 1931; Doguet 1957). Then Malloch (1970) validated the family and accepted genera, Kernia, Lophotrichus and Petriellidium in the family. It has 60 species in 2023.
