Lichenothelia scopularia (Nyl.) D. Hawksw.

Lichenologist, 13: 147, 1981. Basionym: Verrucaria scopularia Nyl. - Not. Sällsk. Fauna. Fl. Fenn. Förh., 6: 282, 1861.

Synonyms: Anzia aterrima (Anzi) Garov.; Buellia anthracina Anzi; Microthelia anthracina (Anzi) Arnold; Microthelia aterrima (Anzi) Zahlbr.; Microthelia scopularia (Nyl.) Blomb. & Forssell; Rinodina aterrima Kremp. ex Anzi

Distribution: N - TAA, Lomb, Piem.

Description: Thallus crustose, black, not lichenized, episubstratic, continuous to areolate, entirely paraplectenchymatous, the cells with a dark brown wall, often destroying the thalli of crustose lichens. Perithecia black, 0.1-0.3 mm across, c. 2/3 immersed in the thallus, without involucrellum, with a finally largely gaping ostiole, so that at maturity they resemble lecideine apothecia with a thick proper magin. Perithecial wall dark reddish brown; paraphysoids branched and anastomosing, 2.5-4 µm thick. Asci 8-spored, clavate tu subcylindrical, bitunicate, thick-walled, apically thickened and with an internal apical beak when young, the wall I-. Ascospores 1-3 tranversely septate or submuriform, at first hyaline, then brown, ellipsoid to soleiform, 12-21 x 5-11 µm, with more or less unequal cells, constricted at the level of the primary septum, with a distinct, 1-2 µm thick gelatinous sheath. Pycnidia deeply immersed in the thallus. Conidia 1-celled, hyaline, 3.5-6 x 0.5-1 µm. Photobiont absent. Spot tests: all negative. Chemistry: without lichen substances.

Note: on metamorphic rocks, sometimes, but only in northern Europe, on rocks inundated by the sea; the Italian distribution seems to be restricted to the Alps.
