In previous molecular phylogenies strain JEL 186, putatively A. sarcoptoides, consistently placed as basal in family Chytriomycetaceae. Recent sampling for chytrids from aquatic habitats resulted in isolation of five additional strains (WJD 209, MP 058, JEL 524, JEL 857, and JEL 885) molecularly related to strain JEL 186. Our morphological evaluations reveal that strains JEL 186 and WJD 209 are members of Asterophlyctis. Strain WJD 209 is considered to be representative of the type, A. sarcoptoides, and strain JEL 186 a new species, A. michiganensis. The four strains MP 058, JEL 524, JEL 857, and JEL 885 are morphologically distinct from Asterophlyctis, and we consider them as members of a new genus, Wheelerophlyctis, composed of two species, W. interior and W. interiexterior. Asterophlyctis and Wheelerophlyctis are sister taxa in our molecular phylogeny, and we demarcate that lineage as Asterophlyctaceae. The two genera also have similar zoospore ultrastructure, which is unique among strains in Chytridiales. In consideration of their molecular phylogenetic position and zoospore ultrastructural features, we hypothesize that Asterophlyctis and Wheelerophlyctis represent a bridge between the two families Chytriomycetaceae and Chytridiaceae. This research expands our concepts of systematics and zoospore ultrastructural variation in Chytridiales. } }
