Coelomycetous fungi classified in Ascochyta, Phoma, and Phyllosticta have been recorded from spots on leaves and pods of soybeans. Based on the Genealogical Concordance Phylogenetic Species Concept, the authors suggest the re-evaluation of the taxonomic status of Phoma sojicola (syn. = Ascochyta sojicola) and Phyllosticta sojicola. In spite of the former delimitation of Phoma sojicola based on small differences in morphological features, it has proved to be identical to Phoma pinodella. Similarly, it was also confirmed that Phyllosticta sojicola was identical to Phoma exigua var. exigua. The authors supply tools for identification of Phoma-like fungi by combined conventional and molecular methods. Protein-encoding genes (tef1 and beta-tubulin) were successfully applied within the Phoma genus to infer phylogenetic relationships. (C) 2008 The British Mycological Society.
