Euopsis pulvinata (Schaer.) Vain.
Meddeland. Soc. Fauna Fl. Fenn., 6: 85, 1881. Basionym: Lecidea pulvinata Schaer. - Naturwiss. Anz., 2: 11, 1818.
Synonyms: Blennothallia haemalea (Sommerf.) Trevis.; Collema haemaleum Sommerf.; Pannaria haemalea (Sommerf.) A. Massal.; Pyrenopsis haemalea (Sommerf.) Norrl.; Pyrenopsis macrocarpa E. Dahl; Pyrenopsis pulvinata (Schaer.) Hellb.
Description: Thallus subcrustose to small-squamulose, homoiomerous, subgelatinous when wet, ecorticate, uniformly dark reddish brown, to 0.3(-0.5) mm thick, forming up to 2 cm wide patches. Thallus anatomy paraplectenchymatous, the hyphae forming a large-celled network around the cyanobacteria. Apothecia formed in a tangle of generative hyphae, to 1 mm across, adnate, with a flat to convex, red-brown, often glossy disc, and a crenulate-squamulose thalline margin containing cyanobacteria. Thalline exciple c. 150 μm thick; proper exciple thin, 10-25 μm wide, of parallel hyphae; epithecium brownish; hymenium colourless, 100-150 μm high, I-, K/I-; paraphyses slender, sparingly branched, septate, gelatinized, not swollen at tips; hypothecium brownish, 70-90 μm high. Asci 8-spored, cylindrical, unitunicate, the wall composed of an outer, non-expansible and an inner, expansible layer surrounding the protoplast as an amyloid collar, which expands during spore release into a long, tapering rostrum, the outer wall layer strongly amyloid, its upper part separated from the expanded amyloid rostrum by a non-amyloid zone. Ascospores 1-celled, hyaline, ellipsoid, 9-15(-17) x (4-)5-8 μm. Pycnidia rare, immersed in warts. Conidia bacilliform, 4-5 x c. 1 μm. Photobiont cyanobacterial, chroococcoid (Gloeocapsa), surrounded by a reddish (in outer parts) to colourless (in inner parts) gelatinous sheath. Spot tests: thallus K-, C-, KC-, P-. Chemistry: without lichen substances.
