Colletotrichum gloeosporioides and Phoma musae isolated from necrotic spots in leaves of Indian coral tree (Erythrina variegata var. orientalis) caused characteristic light brown to tan lesions when inoculated to healthy leaves. C. gloeosporioides caused spots with diffuse margins, whereas P. musae caused spots with distinct dark brown to purple-brown borders. This report represents an extension of the range of C. gloeosporioides on Erythrina and a new host record for P. musae.
