description The <i>Dothideomycetes</i> are a class of cosmopolitan fungi that are present principally in terrestrial environments, but which have also been found in freshwater and marine habitats. In the present study, more than a hundred samples of plant debris were collected from various freshwater locations in Spain. Its incubation in wet chambers allowed us to detect and to isolate in pure culture numerous fungi producing asexual reproductive fruiting bodies (conidiomata). Thanks to a morphological comparison and to a phylogenetic analysis that combined the internal transcribed spacer (ITS) region of the nrDNA with fragments of the RNA polymerase II subunit 2 (<i>rpb</i>2), beta tubulin (<i>tub</i>2), and the translation elongation factor 1-alpha (<i>tef-</i>1) genes, six of those strains were identified as new species to science. Three belong to the family <i>Didymellaceae: Didymella brevipilosa, Heterophoma polypusiformis</i> and <i>Paraboeremia clausa</i>; and three belong to the family <i>Phaeosphaeriaceae:</i><i>Paraphoma aquatica, Phaeosphaeria fructigena</i> and <i>Xenophoma microspora</i>. The finding of these new taxa significantly increases the number of the coelomycetous fungi that have been described from freshwater habitats.
