Ceratocystis fimbriata Ellis & Halst.

This fungus is widely distributed, causing wilt, cankers and other diseases on a large variety of crops. Infections are often lethal to branches or whole plants. Cankers can become infected by other, secondary pathogens. The fungus may be soil-borne or spreads by insects visiting wounds. Commonly infected crops are, for example mango, eucalypt, coffee, rubber (grey mould on the tapping panel) and root crops like sweet potatoes and taro.

Taxonomic studies have found C. fimbriata to be a species complex. Strains infecting cacao and plane trees are now classified as separate species, see:
Ceratocystis cacaofunesta and
Ceratocystis platani
