Absidia spinosa Lendner var. azygospora Boedijn, Sydowia 12: 334-335. 1958.

 Description: Colonies rapidly growing at 25°C, at first white, later gray, and at one month brown. Turf up to 2.5 cm high, still growing at 15°C. Rhizoids present. Sporangiophores 2.5-4.2 μm wide, 64-378 μm long, typically with a septum 13.5-33 μm below the apophysis, simple or 3- 6 arranged in a whirl growing from stolon. Sporangia pyriform, 22.8-30 × 12-31 μm, surface smooth, sporangial wall deliquescing at maturity leaving a collar. Colummellae hemispherical, 8.5-22 μm in diam, smooth, surmounting a funnel-shaped apophysis, projections usually present on upper surface. Sporangiospores cylindrical, 3.6-5 × 2.4-3 μm, smooth, round at both ends. Zygospores absent. Azygospores scattered in the aerial mycelium, orange brown, 30-45 μm in diam, finger-like projections growing from suspensor and surrounding azygospores.

K-6C, isolated from soil, Kenting National Park, Pingtung, Taiwan, March, 1988.

 Note: According to Hesseltine and Ellis (1964) and Boedijn (1958), Absidia spinosa var. azygospora is distinct by the following characters: cylindrical spores; growing fast at 25°C; gray-colored turf; zygospore absent; azygospores abundant. This isolate is with all the characters mentioned above, the author thus identified it as Absidia spinosa var. azygospora.
