Bibl. Lichenol., 26: 38, 1987. Basionym: Verrucaria inductula Nyl. in Hasse - Bull. Torrey Bot. Club, 24: 448, 1897.
Synonyms: Microglaena inductula (Nyl.) Servít; Microglaena sampaiana B. de Lesd.; Polyblastia inductula (Nyl.) Zahlbr.; Thelenella sampaiana (B. de Lesd.) H. Mayrhofer & Poelt
Distribution: S - Si (Ottonello & Puntillo 1995).
Description: Thallus crustose, thinly episubstratic, rimose-areolate, ochraceous to pale reddish brown, covered with a thick epinecral layer. Perithecia brown, globose to pyriform, largely immersed in the thallus, up to 0.3 mm across, with a central, dark brown ostiole. Exciple brown in upper part, colourless in basal part, the upper part covered in an irregular, colourless, epinecral layer; paraphysoids thread-like, c. 1 μm thick, persistent, branched and anastomosing; periphyses absent; hymenial gel I-, K/I-. Asci 8-spored, broadly cylindrical to subclavate, fissitunicate, with two functional wall-layers, the inner wall thin and the outer thick, with an ocular chamber, I-. Ascospores submuriform to muriform, with 6-8 transverse septa and (1-)2-3 longitudinal septa, hyaline, elongate-ellipsoid, 24-33(-36) x 9-12 μm, the outer wall scarcely thicker than the septa. Photobiont chlorococcoid, the algal cells without a gelatinous sheath. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: a mainly Mediterranean lichen found on volcanic rocks, granite and schist, in sheltered and rather shaded, humid situations.
