abstract = {Species concepts are a notoriously difficult taxonomic problem in plant-parasitic fungal-like organisms such as downy mildews (Peronosporomycetes, Peronosporales). This is particularly evident in the largest downy mildew genus, Peronospora, which contains a number of economically important pathogens. Here, we investigate relationships of Peronospora species infecting Fabaceae (angiosperms, Rosidae) originating from various collections from different species of host plants and from different European locations by molecular phylogenetic analysis of internal transcribed spacer (ITS) sequences. Molecular trees were inferred with maximum likelihood (ML), maximum parsimony (MP) and Bayesian methods and rooted with Pseudoperonospora. As in other downy mildew groups, molecular data mainly support the use of narrow species delimitations and host range as a taxonomic marker. Fabaceae parasites appear to be subdivided into a number of lineages displaying a considerable degree of host specialization with respect to both host genera as well as host subgenera or species. The number of repeats of a repetitive part of the ITS1 is, within limits, characteristic of subgroups within the cluster of Trifolium parasites. We reveal new hosts for Peronospora found on the Iberian Peninsula.}
