Index Fungorum number: IF 1724; 3 morphological species (Species Fungorum 2020), 1 species with sequence data.

Generic description: see Rick (1906).

Type species – Dussiella tuberiformis (Berk. & Ravenel) Pat.

Notes: Two species were added to this monotypic genus by Rick (1906) and Höhnel (1907a) respectively. The type species was considered as entomopathogenic, occurring on scale insects, and host jumping onto close plant fungi species (Kepler et al. 2012). The genus is characterized by superficial, subcylindrical perithecia, cylindrical asci with refractive apices, guttulate until the ascospores develop, multi-septate ascospores, breaking into part-spores and 1-septate, lunate conidia, swelling in water (Patouillard 1890, Höhnel 1907a, Kepler et al. 2012). (Adopted from Hyde et al. 2020)

 

Other species: Dussiella orchideacearum Rick

Dussiella violacea Höhn.
