An emendation of the genus Hyaloscypha to include Fuscoscypha (Hyaloscyphaceae, Helotiales, Ascomycotina)

The monotypic genus Fuscoscypha possesses hairs similar as in the genus Hyaloscypha but differs by grey-olivaceous-brown apothecia with short dark stipes.Molecular data proves that the pigmentation does not permit delimitation of a separate genus, as white and brown taxa do not form separate clades.Followingly, Fuscoscypha is here considered to be a synonym of Hyaloscypha.Three of the here treated four species have an olivaceous-brown excipulum.Two are saprophytes on decaying leaves and fruits of angiosperms: F. acicularum, the type species of Fuscoscypha, and Hyaloscypha fuscostipitata comb.nov.(formerly placed in Betulina).Two are biotrophic parasites on Bryophyta: Hyaloscypha hepaticola comb.nov.(formerly placed in Trichopeziza) and the hyaline-excipled Hyaloscypha albocarpa spec.nov.which is otherwise very similar to H. hepaticola.The type species of the genus Betulina, B. hirta, is found to be an earlier synonym of Urceolella salicicola (= U. graddonii).The new combination Urceolella hirta is therefore proposed, hence Betulina is considered a synonym of Urceolella.
