Hedwigia, 54: 195, 1913. Basionym: Polyblastia solvens Anzi - Comm. Soc. Critt. Ital., 2, 1: 27, 1864.
Synonyms: Staurothele meylanii B. de Lesd.; Staurothele solvens (Anzi) Zschacke
Description: Thallus crustose, thinly episubstratic, finely rimose, smooth, pale brownish grey, sometimes with a pinkish tinge. Perithecia at first completely immersed in thallus, later projecting with the black, slightly pruinose, convex apical part, forming 0.6-0.8 mm wide projections. Exciple dark throughout, c. 450 μm across; involucrellum present, thick, limited to the apical part and widely spreading from the ostiolar region; hymenial algae more or less isodiametric; hamathecium of periphyses and periphysoids, interascal filaments absent. Asci 4-spored, clavate, the wall thickened above, with an ocular chamber, after dehiscence with a delicate extruded endotunica, I-, K/I-. Ascospores muriform, at first hyaline then orange-brown, ellipsoid, 40-82 x 18-32 μm. Photobiont chlorococcoid, present in both thallus and hymenium. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
