Definition

Anthracnose is a plant disease caused by acervuli-forming fungi (order Melanconiales) and characterized by sunken lesions and necrosis.

Discussion

Anthracnose of tropical fruits and vegetables is common in Hawaii.  One of the primary fungal pathogens is Colletotrichum gloeosporiodes.  The fungus produces charactersitic pinkish or salmon-colored sticky spore masses within the sunken lesions.
