in Rambold & al., Bibl. Lichenol., 53: 231, 1993. Basionym: Lichen baeomyces L. f. - Suppl. Plant.: 450, 1781 (1782).

Synonyms: Baeomyces roseus f. abortivus A. Massal.; Baeomyces roseus Pers.; Dibaeis rosea (Pers.) Clem.

Description: Primary thallus crustose, grey, white or very pale grey, thick, areolate, usually with soft, rounded, white to pinkish grey, more or less glossy, wart-like, rarely sorediate schizidia which are up to 1 mm wide in sterile thalli, 0.1-0.3 mm wide in fertile thalli. Cortex of thallus c. 50 µm thick, of thin-walled, vertically oriented hyphae; medulla very loose, paraplectenchymatous in parts; cortex of schizidia consisting of interwoven hyphae parallel to the surface; inner part of stalks with strands of thin-walled 2.5-3 µm thick hyphae, those under the hymenium up to 5 µm thick. Apothecia frequent, globose also when young, often hollow inside, pink, 1-4 mm wide, emarginate or with a narrow margin when young, brought on erect, subfruticose, smooth, ecorticate, white stipes (podetia) which are 2-5(-6) mm tall and to 3 mm wide. Proper exciple poorly developed, of radially arranged hyphae; epithecium with colourless crystals dissolving in K (present also in the hymenium); hymenium colourless, 100-120(-140) µm high, K/I+ blue (reaction ephemeral!); paraphyses simple, not anastomosing, 2-2.5 thick at mid-level, the apical cells only slightly wider; hypothecium colourless or yellowish in upper part. Asci 8-spored, thin walled, cylindrical, the walls and tip K/I+ blue, with a distinct ocular chamber in the tholus, Icmadophila-type. Ascospores 1-celled (some apparently 2-celled for the presence of a pseudo-septum), hyaline, fusiform, (10-)12-26 x 2-3 µm. Pycnidia 0.1-0.2 mm across, immersed in warts, mostly laminal, with a colourless wall (brownish near the ostiole), the conidiogenous cells catenate, barrel-shaped. Conidia pleurogenous, short-bacilliform, 3.5-5 x c. 1 µm. Photobiont chlorococcoid (Coccomyxa). Spot tests: thallus K+ yellow-orange, C-, KC+ orange, P+ yellow to orange, UV+ orange; medulla P+ yellow to orange, UV+ orange. Chemistry: baeomycesic acid, and variable amounts of squamatic and barbatic acids and atranorin.
