ITALIC 8.0

Arthopyrenia cinerescens A. Massal.

Symmicta Lich.: 108, 1855.

Synonyms:

Distribution: N - Ven (Lazzarin 2000b), TAA.

Description: Thallus crustose, endosubstratic or thinly episubstratic, greenish grey to lead-grey, sometimes delimited by a dark prothalline line, doubtfuly lichenized. Perithecia black, numerous, hemispherically projecting with a widened base, often clustered. Involucrellum dimidiate; exciple black; paraphysoids persistent but scarce, branched and anastomosing. Asci 6-8-spored, subcylindrical, fissitunicate. Ascospores 3-septate, clavate, hyaline, 15-28 x 4-6 μm. Pycnidia immersed in c. 0.2 mm wide, hemispherical, black warts, with branched conidiophous hyphae. Conidia bacilliform, straight, c. 6 x 2 μm, often arranged in short chains. Photobiont absent or trentepohlioid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: an early coloniser of base-rich bark, also known from Slovenia. The type material was growing on Fraxinus; this is the type species of the monotypic genus Arthopyreniella Stein., based on differences in pycnidial apparatus. According to Harris (1973) material distributed by Massalongo in Lich. Exs. Ital. 43 is Mycoglaena meridionalis (Zahlbr.) Szatala.
