ELLISOMYCES Benny & R. K. Benjamin, 1975 (Aliso 8:330); 1 sp. (Benny and Benjamin, 1975).

Ellisomyces produces sporangiophores that arise directly from the substrate and form bi- or trifurcate apical branches that terminate in a columellate, persistent-walled, globose, multispored sporangium. Zygospores have an undulate zygosporangial wall and opposed, more or less equal suspensors (Benny and Benjamin, 1975).

Type species: E. anomalus

Species of Ellisomyces:
E. anomalus (Hesseltine & Anderson) Benny & R.K. Benjamin, 1975 (Aliso 8:330).

Ellisomyces anomalus was originally described as a species of Thamnidium (Hesseltine and Anderson, 1956). Benny and Benjamin (1975) described the genus Ellisomyces. Most cultures of E. anomalus have been isolated from dung. This fungus can be confused with Piptocephalis when first observed growing on dung. Beakes and Campos-Takaki (1984) and Beakes et al. (1984a, 1984b) studied the ultrastructure and physiology of E. anomalus.
