 Note: Pispek (1929) has enumerated a new scientific name of this species C. polymorpha on the basis of variously branched sporangiophores and variously shaped sporangiola. However, Weitzman & Crist (1980) have demonstrated C. polymorpha and C. bertholletiae as synonyms by their temperature tolerance and branching patterns. C. bertholletiae can be distinguished from other species by its diversely branched sporangiophores and lacrymoid sporangiola. The species is a new record from Taiwan.
