acutatum species complex, but cultures are not available, we have not seen type material, and the species was described from a different continent. Viegas described the species as having conidia that are elongate-fusiform to oblong and 10-20 x 3-5 m in size the description is reminiscent of the C. Colletotrichum eucalypti was described from Brazil by Bitancourt (1927) and noted again by Viegas (1946) from the Campinas region, causing anthracnose of Eucalyptus leaves. Notes: Eucalyptus is not a well-known disease reservoir for Colletotrichum species. Material examined: Indonesia: Sumatra, Tele, from leaf spots developing after herbicide treatment of Eucalyptus sp., 1 Jan.
