B. byssoides B. carneus B. heteromorphus B. lotiformis B. placophyllus B. rufus Baeomyces is a genus of lichenized fungi in the family Baeomycetaceae.

[2] Members of Baeomyces are commonly called cap lichens.

[3][4] The genus was circumscribed by German mycologist Christiaan Hendrik Persoon in 1794.

[5] 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.

[6] As of October 2022[update], Species Fungorum (in the Catalogue of Life) accepts 6 species of Baeomyces.
