Piptocephalis indica B. S. Mehrotra & Baijal, Sydowia, Ann. Mycol. Ser. II, 17: 171-173. 1964.

 Description: Colonies on Cunninghamella sp. on CMA at first white later turning grayish brown; vegetative mycelium becoming septate, much branched. Sporangiophores erect, with rhizoids at the base; main stalks 4-5(-7) µm in diameter, longitudinally striate, septate; branched dichotomously or with whorls of 2-4 primary branches which later again branching into 3 or 4 successive dichotomies; ultimate branches 3.1-4.0 µm long, 2-3 µm in diameter. Head cells small, 4.0-4.5 µm in diameter, heart shaped in side view, with lobes 2-6, usually 3 lobed, each lobe with a merosporangium; the latter about 30 µm long, with spores 3-7. Sporangiospores oblong, smooth, 2-2.5 × 3.8-5.0(-6) µm. Membranes derived from sporangial wall remained on the surface of the spores forming fringes on both ends of the spores. Homothallic. Zygospores formed under or on the surface of the agar media, globose, golden brown, finely warted, 30-47.5 µm in diameter.

 Note: The heart shaped head cells found in my isolate are known in three species, i.e. Piptocephalis xenophila Dobbs & English, Piptocephalis microcephala van Tieghem and P. indica. My isolate resembles P. indica and P. microcephala in the presence of rhizoids, striate sporangiophores and the size of the head cells which roughly varying from 3-4 µm. However, P. microcephala have smaller merosporangia which contains only 3 spores in each at most, while in P. indica, the merosporangia are with 4-7 spores as were observed in my isolate. Thus the author identified this isolate as P. indica.
