　Description： Colonies on PDA, floccos or powdery with black granules on the surface of substrate or immersed in substrate. Ascocarp single, globose, subglobose, black, 56-100 × 50-90 μm; peridium, consisting of pseudoparenchyma. Ascus, broadly ovoid with 8 spores, arranged irregularly, 18.2-25.2 × 9.8-12.6 μm. Ascospores, smooth, thick-walled at matur¬ity, globose, subglobose or ovoid with one germ pore; pale brown initialy, then brown, finally turn to red brown or hessian brown, 8.6-14.7 × 6.4-11.5 μm. Anamorph stage: Colonies on PDA, reaching 78mm at 40° C in 6 days; first white, light orange pink to cream then turning to cinnamon-buff; reverse mars brown, yellow ocher and cinnamon-brown. Conidiophore (fertile hyphae), hyaline, pale yellow green, 1.8-4 μm width, sometime simple, usually irregularly branched; Conidia (blastic spores), attached ter¬minal or laterally, grow directly from hyphae or again from spore, in single or group;When spores detached, with prominent scars at the end. Spores hyaline or pale yel¬lowish green, ovoid or infrequent globose, 3.8-8.3 × 3.2-5.8 μm, wall smooth when young, warty in age.

　Note： Temperature relations: 1. Grow very slow at 22°C, optimum temperature at 40°C. 2. Transfer to 30°C from 40°C for one month, some colonies turned to orange pink with warted spores, otherwise, rest of colonies without color change (maize yellow) with smooth spores. 3. Producing teleomorphic stage at 2 5-30°C.
