The Genus Absidia: Gongronella and Cylindrical-Spored Species of Absidia

Abstract

SUMMARYThe synonymy of the genus Absidia is discussed, and a new subgenus Mycocladus is proposed to include all species of Absidia which have suspensors without long finger like projections surrounding the zygospore. The species of Absidia with cylindrically shaped spores are described and the following new taxa are proposed: A. anomala, A. psychrophilia, and A. cylindrospora var. nigra. The species, A. parricida, is validated. Species recognized as belonging in this group of Absidia are: A. parricida; A. anomala; A. spinosa and its varieties azygospora, madecassensis, and NRRL 3033; A. psychrophilia; A. heterospora; A. fusca; A. pseudocylindrospora; and A. cylindrospora and its varieties nigra and rhisomorpha.
