abstract = {The Blastocladiomycota is a recently described phylum of ecologically diverse zoosporic
fungi whose species have not been thoroughly sampled and placed within a molecular phylogeny. In
this study, we investigated the phylogeny of the Blastocladiomycota based on ribosomal DNA
sequences from strains identified by traditional morphological and ultrastructural characters. Our
results support the monophyly of the Coelomomycetaceae and Physodermataceae but the
Blastocladiaceae and Catenariaceae are paraphyletic or polyphyletic. The data support two clades
within Allomyces with strains identified as A. arbusculus in both clades, suggesting that species
concepts in Allomyces are in need of revision. A clade of Catenaria species isolated from midge larvae
group separately from other Catenaria species, suggesting that this genus may need revision. In the
Physodermataceae, Urophlyctis species cluster with a clade of Physoderma species. The algal parasite
Paraphysoderma sedebokerensis nom. prov. clusters sister to other taxa in the Physodermataceae.
Catenomyces persicinus, which has been classified in the Catenariaceae, groups with the
Chytridiomycota rather than Blastocladiomycota. The rDNA operon seems to be suitable for
classification within the Blastocladiomycota and distinguishes among genera; however, this region
alone is not suitable to determine the position of the Blastocladiomycota among other basal fungal
phyla with statistical support. A focused effort to find and isolate, or directly amplify DNA from
additional taxa will be necessary to evaluate diversity in this phylum. We provide this rDNA phylogeny
as a preliminary framework to guide further taxon and gene sampling and to facilitate future
ecological, morphological, and systematic studies.}
