Melaspilea bagliettoana Zahlbr.

Ann. naturhist. Hofmus. Wien, 19: 413, 1904.

Synonyms: Melaspilea opegraphoides Bagl. non Nyl.

Distribution: C - Tosc, Sar. S - Si (Grillo & al. 2002, Grillo & Caniglia 2004)

Description: Thallus inapparent, doubtfully lichenised. Apothecia ellipsoid, black, epruinose, unbranched, 0.2-0.5 x 0.1-0.2 mm, with an initially slit-like, but soon slightly expanded disc, and a thin proper margin. Proper exciple prosoplectenchymatous, dark brown, 30-36 μm wide, not extending below the hymenium; epithecium brown, K-; hymenium colourless, I+ blue; paraphyses thread-like, simple or sparingly branched and anastomosing in upper part; hypothecium pale brown. Asci 8-spored, elongate-clavate, thickened at apex and with an internal apical beak, K/I-. Ascospores 1-septate, with subequal cells, hyaline to brownish, 12-14(-18) x 4.8-6(-8) μm, when young with flagelliform appendages at both ends. Pycnidia black, semi-immersed. Conidia bacilliform, 8-10 x c. 1 μm. Photobiont trentepohlioid or absent. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a mild-temperate lichen found on smooth bark of trees and shrubs such as Fraxinus ornus and Nerium; mostly Tyrrhenian, very much overlooked. The species might belong to Melaspileella (Ertz & Diederich 2015). It is included in the Italian red list of epiphytic lichens as “Data Deficient” (Nascimbene & al. 2013c).
