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).
