Type speciesCainia graminis (Niessl) Arx & E. Müll.

Notes – The genus was placed in a distinct family because of its longitudinal germ slits in the ascospores and the complex ascus ring comprising a series of rings (Krug 1978). Senanayake et al. (2015) designated a reference specimen for the type Cainia graminis and provided phylogenetic placement to accommodate genera in Cainiaceae.
