As a series of study on pathogenicity of mulberry anthracnose fungi (1), an investigation was made as to whether the pathogenicity of these fungi were specific to the mulberry. Recently proposed 3 species of mulberry anthracnose fungi, Colletotrichum dematium, Glomerella cingulata and C. acutatum, were each inoculated to the detached leaves of plants belonging to 37 species of 21 families. Lesions were formed in most plants after the inoculation was performed on punctured leaves using pieces of mycelial colony of each fungus, especially G. cingulata and C. acutatum, However, the number and size of lesions were decreased when intact leaves were used. Inoculation using conidial suspension of each fungus also made lesion on various plants, but their number depended on the fungi; as to intact leaves, C. dematium made lesions only on Moraceae, Convolvulaceae and Magnoliaceae. We presume that the pieces of mycelial colony, as inoculum, were useful for the assay of pathogenicity. It was concluded that each of the 3 anthracnose fungi was pathogenic to various plants as well as to the mulberry. In addition, our previous identification of the 3 species by morphological characteristics of the conidial was supported by the present results of pathogenicity test.
