Chaetopreussia Locq. -Lin., Revue Mycol., Paris 41(2): 185 (1977).
Saprobic on host. Sexual morph: Ascocarps stromatic, globose, peri-pored, black, with black setae or appendages. Asci claviform, octospores, vanishing. Ascospores cylindrical, hyaline, brown in age, consisting of at least four coffins, almost equal in length, and separate. Paraphysoid filaments present. Asexual morph: Unknown (Adapted from Locquin-Linard, 1977).
Type species: Chaetopreussia chadefaudii Locq.-Lin.
Notes: Chaetopreussia was introduced by Locquin-Linard (1977) with C. chadefaudii as type species. Chaetopreussia is characterized by stromatic, globose, peri-pored, black ascocarps, claviform, octospores asci and cylindrical, hyaline, ascospores. Kruys and Wedin (2009) reported that the cleistothecioid ascomata and the presence of germ slits is not of significant value at the generic rank and Chaetopreussia might be a synonym of Preussia. Chaetopreussia is currently a distinct genus in Sporormiaceae but molecular data is needed to confirm its taxonomic placement.
