Protoblastenia cyclospora (Körb.) Poelt
Mitt. bot. Staatss. München, 12: 5, 1975. Basionym: Biatora cyclospora Hepp ex Körb. - Parerga Lichenol.: 152, 1860.
Synonyms: Biatora rubidula (Nyl.) Walt. Watson; Lecidea cyclospora (Körb.) Müll. Arg.; Lecidea rubidula Nyl.; Protoblastenia globulificans (Nyl.) Zahlbr.
Description: Thallus crustose, endosubstratic or more rarely thinly episubstratic, continuous or rarely finely cracked, pale grey to grey-white, most often inconspicuous. Apothecia biatorine,(0.35-)0.45-0.8 mm across, sessile, slightly to strongly constricted at base, not immersed in pits, with a strongly convex, dark orange-red disc and an indistinct proper margin. Proper exciple poorly developed, of colourless, branched hyphae; epithecium orange-red, 15-25 µm high, with granular crystals reacting K+ red, N-; hymenium colourless or more often with reddish stripes in upper part, 80-100 µm high; paraphyses coherent, sparingly branched and anastomosing, 2-3.5 µm thick at mid-level, the apical cells slightly swollen, 3-4 µm wide; hypothecium yellow-orange to pale orange-red, patchily pigmented. Asci 8-spored, clavate, with a well-developed, amyloid tholus containing a more intensely amyloid, indistinct tube structure, without an ocular chamber, approximating the Porpidia- or Psora-types. Ascospores 1-celled, hyaline, globose or subglobose, (5-)7-9 x 5-7.5 µm, without a distinct perispore. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ purple-red. Chemistry: apothecia with anthraquinones, mainly parietin.
