Protoblastenia incrustans var. coniasis (A. Massal.) Nimis

The Lichens of Italy: 573, 1993. Basionym: Biatora coniasis A. Massal. - Atti I. R. Ist. Ven. Sc. Lett. Arti, 6, 2, ser. 3: 365, 1856.

Synonyms: Lecidea coniasis (A. Massal.) Lettau; Protoblastenia incrustans f. coniasis (A. Massal.) Zahlbr.

Distribution: N - TAA, Lomb, Emil (Tretiach & al. 2008). C - Tosc.

Description: Thallus crustose, endosubstratic, pale ochraceous brown, clearly differing in colour from the rock. Apothecia orange to orange-yellow, 0.2-0.5 mm across, slightly to strongly constricted at base, totally immersed in pits or slightly protruding from the rock, soon moderately convex and immarginate, the disc smooth. Proper exciple poorly developed, of colourless branched hyphae; epithecium orange-brown, with granular crystals reacting K+ red; hymenium colourless, hemiamyloid; paraphyses coherent, sparingly branched and anastomosing, the apical cells hardly swollen; hypothecium colourless to pale yellow. Asci 8-spored, elongate-clavate, with a thin, outer amyloid layer and a thickened tholus penetrated by a tube, the sides of which stain I/KI+ deep blue, Porpidia-type. Ascospores 1-celled, hyaline, ellipsoid to ovoid, 9-15 x 4-6 µm, without a distinct perispore. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ red. Chemistry: apothecia with anthraquinones, mainly parietin

Note: on steeply inclined surfaces of more or less calciferous rocks near and above treeline; certainly more widespread throughout the Alps, but not common, this taxon is well worthy of further study.
