On PDA, growth is rapid, with aerial mycelium abundant, felt-like, rosy buff vinaceous to violet. Colonies reach 4-5.1 cm diameter for 4 days at 24℃. Sporodochia discrete or confluent, straw or orange. Sclerotial bodies sparse to abundant, dark bluish green. Microconidia produced abundantly from monophialides only in false heads, generally single-celled, elliptical to allantoid, 5–12 × 2–3.8 μm, Macroconidia produced abundantly from monophialides, 5–32.5 μm long, on branched or unbranched conidiophores, slightly sickle-shaped, thin-walled, and delicate, with an attenuated apical cell and a foot-shaped basal cell, mostly 3-5 septate, 21.4-50 × 3.5-5.0 μm. Chlamydospores form mostly in hyphae, terminal or intercalary, solitary, in pairs or in chains, 5-15 μm diameter. | |||
