Stapfia, 23: 134, 1990. Basionym: Dermatocarpon sbarbaronis Servít - Ann. Mus. Civ. St. Nat. Genova, 64: 55, 1950.
Synonyms: Catapyrenium sbarbaronis (Servít) Breuss
Distribution: N - Lig.
Description: Thallus squamulose to subcrustose, beige to pale brown, epruinose, thin, closely adpressed, sometimes delimited by a pale prothallus. Squamules 0.4-1 mm broad, rounded to crenate, flattened to slightly convex, smooth, contiguous, mostly forming a subcrustose thallus. Lower surface attached by c. 4 µm thick, pale rhizohyphae. Upper cortex paraplectenchymatous; lower cortex absent. Perithecia black, 0.3-0.35 mm wide, developing from the hypothallus and located among the squamules, at first globose, then pyriform, projecting, with an involucrellum extending all around the perithecium. Exciple dark throughout; paraphyses absent, substituted by periphyses. Asci 8-spored, narrowly clavate, the wall I-. Ascospores 1-celled, hyaline, narrowly ellipsoid, thin-walled, 15-20(-22) x 6-8 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P- UV-. Chemistry: without lichen substances.
Note: only known from the type collection, this terricolous species deserves further study. Indicator values are tentative.
