Colletotrichum higginsianum Sacc. 1917
The fungus causes anthracnose diseases of cruciferous crops. The symptoms are mainly leaf spots but stems, petioles, seed pods and even roots are also attacked. It is especially destructive in the south Atlantic and Gulf states of the U.S.A., but is also found in the Carribean and in south-east Asia.

C. higginsianum is closely related to Colletotrichum destructivum. The conidiomata have brown setae, 60-185 µm long. The conidia are hyaline, smooth-walled, aseptate, cylindrical, straight to very slightly curved, approximately 20 x 4 µm in size. One end is rounded and the other one truncate.
