Saprobic on rodent dung. Sexual morph: undetermined. Asexual morph: Coelomycetous. Conidiomata 120–250 µm diam., 120–250 µm high, dark brown to black, pycnidial, solitary to gregarious, immersed to semi-immersed, globose to subglobose or oval, unilocular, thick-walled, papillate, setose, ostiolate. Ostiole circular, single, centrally located. Conidiomatal setae 2–4 µm wide, septate, branched. Conidiomatal wall 14–30 µm wide, composed of thick-walled, brown to pale brown cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells comprised of two types: a) 6–25 × 1.5–3.5 µm, hyaline, subcylindrical to lageniform, with marked periclinal thickenings at collarette zone, arising from the inner-most cells of the conidiomata at base and lateral part; b) 3.5–7 × 2–3 µm, cylindrical, pale brown at base, becoming hyaline above, formed at upper zone close to ostiole. Conidia 3.5–7 × 2–3 µm ( = 5 × 2 µm; n = 30), hyaline, cylindrical to oval or circular, unicellular, obtuse at each end, guttulate, smooth-walled.
Material examined: USA, California, San Bernardino Co., 1 mile North of Mt. Baldy, on rodent dung, 11 April 1972, D. Malloch (DAOM 215329).
