This is a key to the species of two similar but unrelated genera which potentially occur in Italy (5 species, see Nimis 2016, Nimis & al. 2018):
Dibaeis – A mainly tropical genus of c. 13 species, segregated from Baeomyces on the basis of molecular data and of such characters as apothecial colour, amyloidy of the hymenium, ascus type and secondary chemistry. The genus is more closely related to Icmadophila than to Baeomyces and is presently included in the Icmadophilaceae (Stenroos & al. 2002b). A single species is known from Europe.
Baeomyces – A subcosmopolitan genus of the Baeomycetaceae, with c. 9 species, superficially similar to Dibaeis, but differing in having brown apothecia, a non-amyloid hymenium, a different ascus-type, and a different chemistry.
