The present issue of Studies in Mycology focuses on plant pathogenic Dothideomycetes. The Dothideomycetes represents the largest class of Ascomycota, with more than 100 families and 19 000 species. Of interest, however, is the fact that this class also contains the most genera of plant pathogenic fungi, many of which are frequently encountered by plant health officers at various ports of entry around the world. These officers are subsequently confronted by the fact that the fungus may be expressing its sexual or asexual morph, or worse, maybe sterile mycelium. Traditionally these mycologists have had a range of books with which they could try to identify these organisms based on the phenotype. In recent years however, most of these taxa have been shown to represent species complexes, with some specific to certain regions or hosts. Integrating asexual and sexual names, dealing with species that are cryptic, and genera that are poly- and paraphyletic, and a general lack of DNA data authentic for these species, is a constant stress to which these mycologists are exposed. Identifications made by these mycologists could result in losses of millions of dollars to farmers and producers, while wrongful introductions could again destroy local industries and markets.
The present issue focuses on five main groups of fungi that plant health officers deal with on a weekly, or daily basis, namely Alternaria, Cercospora, Phoma, Pseudocercospora, and Septoria.
