 Note: The sporangiola up to 35 μm long mentioned by Cutter (1964) and Baijal & Mehrotra (1980) are not found in the two strains studied. The paired suspensors of C. blakesleeana sometimes unequal, while other species did not have such phenomenon. So it can be distinguished from other species by this characteristic. The species is newly reported from Taiwan.
