'''''Chytriomyces''''' is the type [genus](/source/genus) of [fungi](/source/fungi) in the [family](/source/Family_(taxonomy)) [Chytriomycetaceae](/source/Chytriomycetaceae). The genus was described by mycologist [John Sidney Karling](/source/John_Sidney_Karling) in 1945.<ref name="Karling 1945"/> The family, created by Peter Letcher in 2011, contains species with a Group I-type [zoospore](/source/zoospore), distinguishing it from [Chytridiaceae](/source/Chytridiaceae) members, which have a Group II-type zoospore.<ref name="Vélez 2011"/>

==Taxonomy==
J. S. Karling circumscribed ''Chytriomyces'' in 1945 for the species ''C. hyalinus'' and ''C. aureus''. The genus was intended to include monocentric chytrids with operculate, apophysate, epibiotic zoosporangia that exhibited vesicular zoospore discharge. Another requirement was resting spores that function as prosporangia during germination.<ref name="Karling 1945"/> With time and the addition of species, the generic concept was altered to include species lacking one or more of these features.<ref name=Sparrow1960>{{cite book |author1=Sparrow F.K. |title=Aquatic Phycomycetes |year=1060 |edition= second |publisher=The University of Michigan Press |pages= 624–627, 669–670 }}</ref><ref name=Letcher2002>{{cite journal |last1=Letcher |first1=Peter M. |last2=Powell |first2= Martha J. |date=2002 |title=A taxonomic summary of ''Chytriomyces'' (Chytridiomycota) |journal=Mycotaxon |volume= 84 |pages=447–487}}</ref> Karling was not clear as to which of his species was the type; ''C. hyalinus'' was later designated the type.<ref name=Letcher2002/> With the use of molecular phylogenetics, it has been determined that several species in this genus did not belong. For example, it was shown that ''C. poculatus'' and ''C. angularis'' were better classified in the new genus ''Lobulomyces''.<ref name=Simmons2009>{{cite journal |last1= Simmons |first1=D.
