 Note: Because there are no significant differences in the morphological characteristics between C. elegnas and C. bertholletiae, Zycha (1935), Mil’ko & Beljakova (1967), Samson (1969) and Baijal & Mehrotra (1980) have considered them as the same species. However, Cutter (1946), Weitzman & Crist (1980) and Weitzman (1984) have distinguished them as two valid species by their conspicuously different temperature tolerance and branching patterns, as well as the inability to form zygospore when paired. The species can be distinguished clearly from the others by its maximal temperature tolerance below 38℃.
