Baeomyces is a genus of lichenized fungi in the family Baeomycetaceae. Members of Baeomyces are commonly called cap lichens.[1] [2] The genus was circumscribed by German mycologist Christiaan Hendrik Persoon in 1794. Although Persoon did not designate a type species in his original description of the genus, Frederick Clements and Cornelius Lott Shear assigned Baeomyces byssoides as the type in 1931.
, Species Fungorum (in the Catalogue of Life) accepts 6 species of Baeomyces.
