Abstract

The phylogenetic relationships among 44 isolates representing 16 species of Stemphylium were inferred from ITS and glyceraldehyde-3-phosphate dehydrogenase (gpd) gene sequence data. The results generally agree with morphological species concepts. There was strong support for monophyly of the genus Stemphylium. Analysis of the gpd fragment in particular was useful for establishing well-supported relationships among the species and isolates of Stemphylium. Species of Stemphylium that appear to have lost the ability to produce a sexual state are scattered among the species with the ability to reproduce sexually (Pleospora spp.). Species that are pathogenic to alfalfa are resolved into two groups. Stemphylium botryosum and two isolates with morphological characters similar to S. globuliferum had identical sequences at both loci. These two loci in S. vesicarium, S. alfalfae and S. herbarum are nearly identical but differ from S. botryosum. The separation of S. vesicarium, S. herbarum and S. alfalfae into separate species by morphometric evidence was not supported by the molecular data. Morphological and developmental characters such a size and shape of conidia, conidiophores, and ascospores, and size and time of maturation of pseudothecia are useful for diagnosing species. However, other morphological characters such as septum development and small variations in conidial wall ornamentation are not as useful.
