Willdenowia, 5: 375, 1969. Basionym: Lecidea scabra Taylor in Mackay - Fl. Hibern., 2: 121, 1836.
Synonyms: Lecidea continuior var. subviridans Nyl.; Lecidea elaeochroma var. pulverulenta Th. Fr.; Lecidea enterochlora Taylor; Lecidea prasinula (Wedd.) B. de Lesd.; Lecidea protrusa Fr.; Lecidella prasinula (Wedd.) Hertel nomen sed non planta; Lithographa larbalestieri Leight.
Description: Thallus crustose, episubstratic, rimose to areolate, 0.1-0.3(-0.4) mm thick, greenish grey to grey-yellowish green, sorediate, the soredia granular, 20-30(-40) µm in diam., arranged in initially discrete and up to 1.2 mm wide, then often confluent, greenish to yellowish white soralia which appear grey-green when abraded. Cortex filled with crystals, patchily overlain by a 10-20 μm thick epinecral layer; medulla white, with crystals, I-. Apothecia rather rare, lecideine, dull black, slightly constricted at base, 0.7-1.6 mm across, with a flat to weakly convex disc and a thin proper margin. Proper exciple greenish black to dark brown in outer part, brown to reddish brown within, sometimes with crystals; epithecium bright green to blackish green, 10-20 μm high, K-, N-; hymenium colourless, 50-80 µm high, not inspersed with oil droplets; paraphyses easily made free in K, simple, rarely anastomosing or branched in upper part, 1-2 μm thick at mid-level, the apical cells 2-3 μm wide; hypothecium yellowish brown to brown. Asci 8-spored, clavate, with an intensely K/I+ blue tholus penetrated by a faintly amyloid, broadly cylindrical axial mass, and a poorly developed ocular chamber, the wall K/I-, surrounded by a K/I+ blue outer layer, approaching the Lecanora-type. Ascospores 1-celled, hyaline, broadly ellipsoid to ovoid, thick-walled, 10-15(-18) x 6-8(-10) µm. Photobiont chlorococcoid. Spot tests: thallus K+ yellow (rarely K-), C+ orange-yellow, KC+ orange, P+ yellow to rarely P-, UV+ orange. Chemistry: atranorin, chloroatranorin, 4,5-dichloro-3-O-methylnorlichexanthone, 4,5-dichloronorlichexanthone, arthothelin, asemone, thiophanic acid and thuringione.
Growth form: Crustose
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
