Description: Thallus crustose, thinly episubstratic, grey-green to yellowish, granular-verruculose, composed of 14-40 µm wide, unpigmented goniocysts. Perithecia frequent, black, but often with a greyish tinge when young (due to a thin, unpigmented surface layer), globose to broadly ovoid, 0.3-0.7 mm across, immersed. Involucrellum absent; exciple dark-pigmented throughout, the pigment brown to reddish brown, K + dark greyish brown; hamathecium of periphyses and periphysoids, interascal filaments absent, the periphysoids branched; hymenial gel hemiamyloid, I+ red (I+ blue at very low concentrations of I), K/I+ blue. Asci 8-spored, broadly clavate, bitunicate-fissitunicate, thick-walled above when young, with a small ocular chamber, Verrucaria-type. Ascospores 1-celled (overmature spores sometimes 2-3-septate), hyaline, narrowly ellipsoid, (15-)19.5-25(-29) x (5-)6-7(-8) µm, often truncate at the ends and with gelatinous appendages measuring 2-3.5 x c. 1 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
