| Description： |
Colonies on PDA grown well, reaching 92 mm in 3 days at 40°C, white at first, brownish gray or mouse gray latter; reverse grayish brown. Vegetative hyphae have rhizoid, developed poorly, hyaline, not limited under the sporangiophore. Sporangiophore smooth or some have crystals, grown from any site of vegetative mycelium, seldom branched in young or at 50°C, strongly branched at maturity in alternate, opposite, sympodial or in group at the apex, nonseptate or have septate at branching site. The primary sporangia are globose, subglobose, brown, the surface covered with short spine, 25.2-48.6 × 23.8-43.4 μm. The sporangia of the branches (secondary sporangia) are smaller than the apex. Columellae smooth or slightly with protrusions, globose, subglobose, oblate, with or without collaret, pale gray or pale yellowish brown or brown, hyaline, 9.8-58.8 × 9.8-49 μm; At 50°C, columellae become thick-walled. Sporangiospores smooth, globose, subglobose, elliptical or irregular in shape, pale green, 2.9-7 × 2.9-8.3 μm. Zygospore not observed. | |||
