摘要

Numerous coelomycetous fungi classified in Ascochyta, Phoma and Phyllosticta, and lately established and/or re-classified genera and species, namely Boeremia and Peyronellaea have been recorded from spots on leaves and pods of soybeans. These rarely observed pathogens are cosmopolitan, ubiquitous species on diseased and dead plant materials, and define frequently as weak or opportunistic parasites. Based on the Genealogical Concordance Phylogenetic Species Recognition, the authors summarize the re-evaluation of the taxonomic status of Phoma sojicola (syn. Ascochyta sojicola) and Phyllosticta sojicola. Inspite of the former delimitation of Ph. sojicola based on small differences in morphological features, it has proved to be identical to Peyronellaea pinodella (syn. Phoma pinodella). Similarly, it was also confirmed that Ph. sojicola was identical to Boeremia exigua var. exigua (syn. Phoma exigua var. exigua). The authors and co-workers contributed to the 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.
