CHLAMYDOABSIDIA Hesseltine & Ellis, 1966 (Mycologia 58:761); 1 sp. (Hesseltine and Ellis, 1966).

Chlamydoabsidia (Hesseltine and Ellis, 1966) resembles Absidia because it forms multispored sporangia with a prominent columella and a deliquescent wall. A single septum is produced in the sporangiophore subtending the sporangium. Large, pigmented, more or less fusiform, multiseptate chlamydospores are formed in the aerial mycelium. Zygospores are unknown.

Type species: C. padenii

Species of Chlamydoabsidia:
C. padenii Hesseltine & Ellis, 1966 (Mycologia 58:763).

This genus was described (Hesseltine and Ellis, 1966) based on C. padenii. Chlamydoabsidia padenii was transferred to Absidia by Mil’ko (1968, 1970) and Váňová (1980). The second species, C. dasguptii (Behera and Mukerji, 1974), is considered a synonym of C. padenii according to the Index of Fungi online (


Behera, N., and K. G. Mukerji. 1974. Fungi of Delhi. XXV. Chlamydoabsidia dasgupti n. sp. and Polyschema indica Behera, Mukerji & Sharma. Norw. J. Bot. 21: 1-3.
