Cat. Lich. Univ., 7: 518, 1931. Basionym: Lecanora ficta Stizenb. - Ber. Tät. St Gall. naturw. Ges.: 210, 1890.

Synonyms: Rinodina boleana Giralt & H. Mayrhofer

Distribution: N - Frl (Giralt & Mayrhofer 1995), VA (Ongaro & al. 2022). S - Si (Nimis & al. 1994, Giralt & Mayrhofer 1995).

Description: Thallus crustose, episubstratic, thin or evanescent, minutely granulose, pale to dark grey, grey-brown to greenish grey, without a distinct prothallus. Apothecia lecanorine, sessile, 0.2-0.4 mm across, with a flat to slightly convex, dark brown to rarely black disc and a thin, entire, usually persistent thalline margin. Thalline exciple 30-50(-60) µm thick, indistinctly corticate, the cortex up to 15 µm thick; proper exciple colourless, 5(-10) µm thick laterally; epithecium dark brown, without epipsamma; hymenium colourless, 45-70 µm high; paraphyses mostly simple, lax, 1.5-1.8 µm thick at mid-level, the apical cells 3-6 µm thick; hypothecium colourless to very pale brown. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-septate, brown, ellipsoid, straight or curved, (10-)13-16 x (4.5-)5-8 µm, Pachysporaria-type, with a usually poorly developed torus and ontogeny of type B (apical thickenings visible before the insertion of the septum). Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: on evergreen broad-leaved trees in parklands, waysides, and in open maquis or woodlands; also known from South Africa, New Zealand, North America, the Iberian Peninsula, Greece and Croatia, this species is probably more widespread in Mediterranean Italy. It was included in the Italian red list of epiphytic lichens as “Data Deficient” (Nascimbene & al. 2013c). For nomenclatural matters see Mayrhofer & al. (2014).
