Pleopsidium chlorophanum (Wahlenb.) Zopf

Ann. Chem., 284: 117, 1895. Basionym: Parmelia chlorophana Wahlenb. in Ach. - Meth. Lich. Suppl.: 44, 1803.

Synonyms: Acarospora chlorophana (Wahlenb.) A. Massal.; Acarospora flava var. chlorophana (Wahlenb.) Stein; Gussonea chlorophana (Wahlenb.) Tornab.

Description: Thallus crustose-placodioid, bright yellow, epruinose, areolate to rimose-areolate in central parts, forming more or less orbicular, 1-2 cm wide rosettes, several thalli often merging to cover large surfaces. Central areoles mostly angular, flat to convex, 0.4-2(-4) nm wide, 0.4-1 mm thick; marginal lobes poorly developed, 1-3 x 0.3-1.5 mm, contiguous, smooth, with expanded, blunt apices. Cortex prosoplectenchymatous, of small-celled hyphae, pale yellow throughout, inspersed with crystals, 30-60 µm thick, yellow in upper part, colourless in lower part; algal layer continuous or irregularly interrupted; medulla white, intricately prosoplectenchymatous. Apothecia (0.6-)1(-2) mm across, crowded, covering the central parts of thallus, with a yellowish, sometimes slightly darkened, convex disc and a soon excluded thalline margin, appearing biatorine at maturity. Proper exciple colourless, 50-80 µm wide; epithecium greenish or brownish yellow, inspersed with yellowish crystals, 15-20 µm high; hymenium colourless, 50-60(-70) µm high, I+ blue; paraphyses mostly simple, separating easily, 1.5-2 µm thick at base, the apical cells slightly expanded, 2-3 µm wide; hypothecium colourless, I+ brown-yellow or pale blue. Asci 100-200-spored, clavate, with a distinct apical dome reacting I+ deep blue only in the lower outer part, a broad ocular chamber, and an amyloid outer gelatinous sheath, Pleopsidium-type. Ascospores 1-celled, hyaline, ellipsoid, 3-4 x 1.5-2 µm. Pycnidia immersed, poorly evident, the jelly I+ blue. Conidia broadly ellipsoid, often narrower at one end, (3-)3.5-4.5 x 1.5-2 µm. Pycnidia yellow, immersed, poorly evident. Conidia ellipsoid, 3-3.8 x 1.5-1.8 µm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K-, C-, KC-, P-, UV+ orange. Chemistry: rhizocarpic acid plus fatty acids (acaranoic, acarenoic acids).
