H esseltine , C. W. (Northern Utilization Research and Development Division, Peoria, Ill.) The zygosporic stage of the genus Pirella (Mucoraceae). Amer. Jour. Bot. 47(3) : 225—230. Illus. 1960.– Pirella circinans Bainier has been found to be heterothallic. The zygospores, which have never before been reported, are formed when + and – strains are mated at 15°C. on such media as tomato paste‐oatmeal or potato dextrose agars. Zygospores are formed in a diffuse manner in the aerial mycelium and are similar to those found in the genus Mucor . The single species, P. circinans, is described on a synthetic medium and its synonyms are listed. It is believed to represent a genus between Mucor and the family Thamnidiaceae.
