Verrucaria alpicola Zschacke
Hedwigia, 67: 75, 1931.
Synonyms:
Description: Thallus crustose, episubstratic, 15-50 μm thick, subgelatinous when wet, usually cracked at least around the perithecia, smooth, pale to usually dark grey-brown to almost black. Cortex paraplectenchymatous, with a yellowish to black-brown pigment, the upper layer darker; medulla white, rarely with a thin black basal layer. Perithecia black, covered with a thalline layer, forming distinct, 0.4-0.8 mm wide projections. Involucrellum 17-38 μm thick, reaching to base-level and laterally spreading; exciple 0.24-0.34 mm across, the wall brown throughout; hamathecium of (15-)25-35(-43) μm long periphysoids, interascal filaments absent; hymenial gel hemiamyloid, I+ red (I+ blue at very low concentrations of I), K/I+ blue. Asci 8-spored, clavate, I-, fissitunicate, the wall thickened above, with an ocular chamber, dehiscent by extrusion of an endotunica to form a delicate rostrum, Verrucaria-type. Ascospores 1-celled, hyaline, ellipsoid to narrowly ellipsoid, (20-)23-35(-43) x (9-)12-16(-19) μm, (1.5-)1.7-2.3(-3.6) times as long as wide, without a gelatinous perispore. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
