Lecidea rapax Hertel
Herzogia, 1: 426, 1970.
Synonyms:
Description: Thallus crustose, episubstratic, 0.5-2 mm thick, areolate, of flat to convex, up to 3 mm wide, yellow-brown, copper-brown or dark reddish brown areoles with a whitish to grey edge (without the production of thallospores), constantly growing on the thalli of Bellemerea alpina or B. cinereorufescens; prothallus absent or usually conspicuous, dark, but sometimes absent. Algal layer strongly discontinuous; medulla white, I+ intensely blue-violet. Apothecia lecideine, black, 0.5-1.1(-1.5) mm across, often clustered, constricted base, with a flat to convex, rarely bluish-pruinose disc and a persistent, raised, often slightly wavy proper margin. Proper exciple of parallel-radiating, 3-7 µm thick hyphae, blue- to green-black in outer part, colourless or very pale brown within, C-; epithecium olive-green; hymenium colourless to very pale greenish in upper part, 40-55 µm high, I+ blue; paraphyses coherent, usually simple, rarely anastomosing, 2-2.5 µm thick at mid-level, the apical cells clavate, to 4 µm wide; hypothecium brown, I+ blue. Ąsci 8-spored, clavate, Lecidea-type. Ascospores 1-celled, hyaline, ellipsoid-oblong, with rounded ends, 7-10 x 3.5-4.5(-5) µm. Pycnidia dark, immersed. Conidia 5-10 µm long. Photobiont chlorococcoid. Spot tests medulla K+ yellow turning red (needle-like crystals), C-, KC-, P+ yellow. Chemistry: norstictic acid syndrome.
