To resolve the polyphyletic nature of as it was originally circumscribed, we establish a new family for those genera originally placed in that have aquatic hyphomycete-like asexual morphs and/or a sexual morph with glabrous apothecia. These include , , , , , , and . is confined to the genera , and , all of which have a sexual morph having apothecia with smooth-walled hairs. This taxonomy is supported by a multi-gene analysis using up to 15 genes, with a few of the taxa placed on the basis of a separate ITS phylogeny. forms a monophyletic clade with a basal sister relationship to plus ; forms a monophyletic clade with a basal sister relationship to .
