Abstract

Several hyaline-spored coelomycetes placed in Ascochyta, Phoma and Phyllosticta have been recorded from spots on leaves and pods of soybean. Comparison of herbarium material, pathogenicity tests and in vitro studies have demonstrated that Phoma sojicola comb. nov. (syn. Ascochyta sojicola) was predominantly involved as a pathogen of soybean. The diagnostic characters and history of this fungus and other hyaline-spored coelomycetes occurring on soybean are described.
