abstract = {Many chytrid phylogenies contain lineages representing a lone taxon or a few organisms. One such lineage in recent molecular phylogenies of Rhizophydiales contained two marine chytrids, Rhizophydium littoreum and Rhizophydium aestuarii. To understand the relationship better between these organisms, we increased sampling such that the R. littoreum/R. aestuarii lineage included ten strains of interest. To place this lineage in Rhizophydiales, we constructed a molecular phylogeny from partial nuc 28S rDNA D1?D3 domains (28S) of these and 80 additional strains in Rhizophydiales, and examined thallus morphology and zoospore ultrastructure of our strains of interest. We also analyzed sequences of the nuc rDNA region encompassing the internal transcribed spacers 1 and 2, along with the 5.8S rDNA (ITS) of our ten strains of interest to assess sequence similarity and phylogenetic placement. The ten strains grouped together in three well supported clades: (1) Rhizophydium littoreum + Phlyctochytrium mangrovei, (2) three strains of Rhizophydium aestuarii, and (3) five previously unidentified strains. Light microscopic observations revealed four distinct thallus morphologies, and zoospore ultrastructural analyses revealed four distinct constellations of ultrastructural features. On the bases of morphological, ultrastructural, and molecular evidence, we place these strains in the new family Halomycetaceae and four new genera (Halomyces, Paludomyces, Ulkenomyces, and Paranamyces) in Rhizophydiales. }
