UTHAROMYCES Boedijn, 1959 (Sydowia 12:340); 1 sp. (Kirk and Benny, 1980—monograph).

Utharomyces sporangiophores arise directly from a trophocyst in the substrate, simple, bearing a sporangium apically. Sporangia globose above and somewhat flattened below, columellate, multispored, wall persistent; a vesicle is formed in the sporangiophore slightly below the sporangium. Sporangiospores are convex with a flat, ormamented edge. Zygospores are unknown (Kirk and Benny, 1980).

Type species: U. epallocaulus

Species of Utharomyces:
U. epallocaulus Boedijn ex P.M. Kirk & Benny, 1980 (Trans. Brit. Mycol. Soc. 75:124).

Utharomyces was initially described from Indonesia (Boedijn, 1958) but it was later reported from Africa and India. Kirk and Benny (1980) reported Utharomyces from Mexico, Bahamas, and Taiwan. This fungus has also been collected in Florida. Mikawa (1979) reported U. epallocaulus from Japan. The majority of the collections of Utharomyces have been made from dung.

Utharomyces epallocaulus was invalid because the type was not indicated after 1 January 1958 as required in Art. 37.1 of the ICBN (Greuter et al., 2000). Neotypes have been designated for two of Boedijn’s (1958) other monotypic genera, Phascolomyces articulosis and Sporodiniella umbellata (Benny and Benjamin, 1976; Evans and Samson, 1977). Rhizopodopsis javanicus is not known to be in culture and a neotype has not been designated.
