Conidiobolus thromboides Drechsler, J. Wash. Acad. Sci. 43: 38 (1953). Basionym.
Specimens examined. China, Anhui Province, Plant detritus, 21 Feb 2009, C.F. Wang, RCEF 4492.
Description. Colonies grown on PDA for 3 d at 25 °C, white, reaching ca. 30 mm diameter. Mycelium colourless, filamentous, 5–7.5 μm wide. Primary conidiophores colourless, unbranched and producing a single conidium, 50–122.5 × 6–16.5 μm. Primary conidia forcibly discharged, colourless, globose to subglobose, 20–26.5 μm wide, 26.5–34 μm long, including a basal papilla 6–10 μm wide. Secondary conidia globose, forming from the primary conidia. Zygospores most often formed between segments of separate hyphae. Mature zygospores smooth, globose to subglobose, 25–30 μm in diameter with wall 2–3 μm thick.
Notes. The ex-type living culture is ATCC 12587 (United States, New Hampshire, September 1957, Drechsler).
