【 摘 要 】

Colletotrichum karstii is reported, for the first time, causing anthracnose on the native Brazilian orchid Cattleya walkeriana. Identification was confirmed through a combination of morphological and molecular (phylogenetic analysis of the ITS, GAPDH and TUB2 regions) data. Koch’s postulates were fulfilled through the inoculation of C. karstii on C. walkeriana.
