Thelenella justii (Servít) H. Mayrhofer & Poelt

Herzogia, 7: 61, 1985. Basionym: Microglaena justii Servít in Zschacke - Rabenh. Krypt.-Flora, 9, 1: 665, 1934.

Synonyms:

Distribution: C - Laz.

Description: Thallus crustose, endosubstratic or very thinly episubstratic, film-like, dirty white. Perithecia globose, up to 0.5 mm across, pale, with a centrally located, pale reddish brown ostiole, scattered, immersed. Exciple colourless; paraphysoids thread-like, c. 0.5 μm thick, sparingly branched and anastomosing; hymenial gel I-, K/I-. Asci 8-spored, broadly cylindrical, fissitunicate, with two functional wall-layers, the inner wall thin and the outer thick, with an ocular chamber, I-. Ascospores submuriform to muriform, with 11-15 transverse septa and 1-2 longitudinal septa, hyaline, elongate-ellipsoid to fusiform, with pointed ends, 35-50 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 mild-temperate lichen described from Greece (on the bark of AbIes cephalonica), also found on the bark broad-leaved trees and shrubs in sheltered situations, with optimum in the montane belt, descending to the submediterranean belt in particularly humid areas of Tyrrhenian Italy. It was included in the Italian red list of epiphytic lichens as “Data Deficient” (Nascimbene & al. 2013c).
