- Abstract
Systematics of Chytridiales has been deeply influenced by analyses of molecular loci and zoospore ultrastructure. Even though the Chytridiales is the largest order within Chytridiomycota, Brazilian isolates of this clade have been poorly integrated. Here, we isolated seven species and documented their morphology, including zoospore ultrastructure for Siphonaria aurea , and phylogenetic positions for all based on analyses of nuc 18S and 28S rDNA. Phylogenetic results support the placement of these species in Chytriomycetaceae and Chytridiaceae, with two new species described, Rhizidium crepaturum and Siphonaria aurea , and Rodmanochytrium sphaericum recorded for the first time from Brazil.
