Abstract

The cosmopolitan Phoma genus contains mainly phytopathogenic, opportunistic parasite, and saprophyte fungal species. The currently applied classification is based on morphological characters. In this study, a preliminary classification for six taxa of Phoma were constructed, viz. P. exigua var. linicola, P. pinodella, P. eupyrena, P. herbarum, P. foveata, and P. destructiva, based on DNA sequence data of translation elongation factor1 subunit (EF1 = tef1). The six Phoma species were compared to two species of the closely related Ascochyta genus, and was divided into two clades. The phylogenetic tree based on tef1 sequences does not support the traditional Phoma sections set up by morphological characters.
