China, Anhui Province, Plant detritus, 8 Nov 2008, C.F. Wang, RCEF 4445.

Description.

Colonies on PDA at 21 °C after 3 d white, flat, slow-growing, reaching ca. 13 mm in diameter. Mycelia colourless, 5.5–11 μm wide. Primary conidiophores, positively phototropic, arising from hyphal segments, colourless, 28–75 × 7.5–10 μm, unbranched and producing a single globose conidium. Primary conidia forcibly discharged, globose, 27–37 × 21–28 μm, with a basal papilla 6–10 μm wide. Secondary conidia arising from primary conidia, similar to, but smaller than the primary ones, forcibly discharged. Tertiary conidium fusiform arising from primary conidia, 30–45 × 16–22 μm. Zygospores in a position separated by a short beak near a lateral conjugation, globose to subglobose, smooth, 21–25 × 17–24 μm, with a 1–2 μm thick wall.

Notes.

The ex-type living culture is ARSEF 6378 (United Kingdom, Staffordshire, Plant detritus, 31 October 1983, M. F. Smith).
