Aspiciliella cupreoglauca (B. de Lesd.) Zakeri, Divakar & Otte

Herzogia, 30, 1: 172, 2017. Basionym: Aspicilia cupreoglauca B. de Lesd. - Bull. Soc. Bot. France, 57: 32, 1910.
Synonyms: Aspicilia cinerea var. rubicunda Bagl.
Distribution: C - Tosc, Laz, Sar (Monte 1993, Nöske 2000, Rizzi & al. 2011). S - Si (Grillo & Caniglia 2004).
Description: Thallus crustose, episubstratic, areolate, 0.3-0.6 mm thick, grey to pale brown depending on the amount of pruina (the epruinose parts pale brown and somehow glossy, the pruinose parts pale grey and matt), forming well-delimited, several cm wide, orbicular patches. Areoles angular 0.3-1 mm, wide, slightly concave to flat, with a white-pruinose margin. Cortex paraplectenchymatous, 40-50 µm thick, overlain by a 10-16 µm thick epinecral layer, the upper part brown (Subdepressa-brown pigment), K-, disappearing in N); algal layer of irregular thickness; medulla white, I-. Apothecia lecanorine-aspicilioid, round to irregular-angular in outline, immersed in the areoles, 0.2-0.5 mm across, with a concave to flat, black, epruinose disc and a thin, persistent, slightly raised thalline margin. Epithecium green to olive-green or greenish brown, N+ brighter green; hymenium colourless, 145-170 µm high; paraphyses coherent, moniliform in upper part; hypothecium colourless, not subtended by an algal layer. Asci 6-8-spored, clavate, the thin outer coat K/I+ blue, the wall and apical dome K/I-. Ascospores 1-celled, hyaline, ellipsoid, 20-32 x 12-16(-20) µm, thin-walled, 1-2-seriate in the asci. Pycnidia immersed, with a black, punctiform ostiole. Conidia bacilliform, straight, 6-8 x c. 1 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K+ yellow turning red (needle-like crystals), C-, KC-, P+ yellow-orange. Chemistry: norstictic, connorstictic and constictic acids.
Note: a mild-temperate to Mediterranean lichen found on base-rich siliceous rocks wetted by rain, mostly on horizontal surfaces; mainly Tyrrhenian in Italy.
