Several unnamed forms of C. fimbriata appear to be indigenous to North and South America or Asia but have been introduced elsewhere. Different hosts are attacked in different regions, and even in regions where the fungus is common, not all potential hosts are attacked. For example, mango wilt is known only in Brazil, although Mangifera is grown in other areas where C. fimbriata is common on other plants. The Theobroma form is restricted to Central America and northern and eastern South America, while Coffea forms apparently occur only in Central America and northern South America and, perhaps, a few locations in South-East Asia (Zimmerman, 1900).
