Morphological 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.
