The species is one of the basic units of biological classification. Both species concepts and recognition are essential topics in taxonomic studies and other biological research. In the first part of this review, we briefly discuss the taxonomic history of the class Dothideomycetes. In the second part of the paper, we review four commonly used species concepts, focusing on morphological, ecological, biological and phylogenetic criteria and their applicability in the taxonomy of Dothideomycetes. The application and utility of the four criteria is discussed with examples in the genera Ascochyta, Cercospora and Neofusicoccum. Some problems and challenges of studying Dothideomycetes are analyzed and basic guidelines for classifying species under the above criteria are provided.
