Colonies at 25℃ spreading rapidly, grey on maturity, growing well at 40℃; sporangiophores erect, with solitary, opposite, verticillate or irregular branches, the laterals sometimes showing secondary branching; terminal vesicles subglobose to obovate, 14.8-41.2 μm in width, average 30.6 μm, lateral vesicles smaller than terminal ones, but no conspicuous difference in shape, 12-28.8 μm in width, average 19.1 μm; sporangiola hyaline to pale brown, spherical to ellipsoid, occasionally lacrymoid, 5.6-11.4 × 5.2-8.8 μm in diameter, average 7.8 × 7.0 μm, smooth to echinulate with very short spines; chlamydospores subglobose to broadly ellipsoidal, average 21.86 × 18.83 μm in diameter; Heterothallic.
worldwide distribution, mainly Mediterranean and subtropical zones.

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.
