　Description： Colonies rapidly growing on CMA at 25°C, with dense aerial mycelium, at first white, later becoming orange colored. Sporangiophores bearing sporangia arising from substrate mycelium, erect or ascending, non-septate, unbranched, 1-4 mm high, hyaline, 11-14 µm wide, curved at the apex. Sporangia spherical, 30-90 µm diameter, initially white but turning to very dark brown with age. At maturity, sporangial wall persistent, encrusted with short spines, dehiscing at maturity into 2 segments. Sporangiospores from sporangia ellipsoid to broadly ellipsoid, reddish-brown, longitudinally striate, 16-22 µm long, 8-12 µm wide, with a group of fine appendages at each pole often up to twice the length of the spore. Sporangiophores bearing sporangiola arising from substrate mycelium or aerial hyphae, erect or ascending, 1-5 mm high, unbranched at the basal portion, non-septate, smooth walled, 36-44 µm wide, dichotomously branched at the apex once to twice. Branches with irregular successive constrictions, ultimate branches terminating in spherical enlargements, 30-44 µm diameter, upon which the sporangiola are borne over the entire surface, each sporangiophore bearing l-4 enlargements. Sporangiola ellipsoid to broadly ellipsoid, 14-25 µm long, 10-14 µm wide, containing one (rarely two) sporangiospore, with a persistent wall, hyaline, breaking along a preformed suture at maturity, attached to the spherical enlargements by a small, cylindrical pedicel, 2-5 µm long, 2.5 µm wide. Sporangiospores from sporangiola ellipsoid to broadly ellipsoid, reddish brown, longitudinally striate, 12-24 µm long, 8-12 µm wide, with a group of fine, hyaline appendages at each pole often equal to the length of the spore. Zygospores were not found.
