Protoblastenia szaferi J. Nowak

Fragm. Flor. Geobot. (Kraków), 20, 4: 529, 1974.
Synonyms:
Distribution: N - Frl (Nascimbene & al. 2021).
Description: Thallus crustose, endosubstratic, forming 1-2(2.5) cm wide, sometimes confluent, well-delimited white patches, without a distinct prothallus. Apothecia bright orange, 0.4-0.8 mm across, immersed in shallow pits in the rock and separated from the rock by a marked cleft, later slightly projecting, with a persistently flat disc and a paler marginal rim. Proper exciple poorly developed, near the hymenium consisting of subparallel hyphae, the intercellular spaces filled with a mixture of anthraquinone and oxalate crystals, the outer rim composed of interwoven hyphae inspersed with oxalate crystals; epithecium orange, with granular crystals reacting K+ red; hymenium colourless but appearing pale orange due to scattered anthraquinone crystals, c. 60-70 μm high, hemiamyloid; paraphyses shortly septate, sparingly branched and anastomosing, 2.5-3 μm thick, the apical cells hardly swollen; hypothecium colourless, of interwoven hyphae, with scattered clusters of oxalate crystals. 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, ellipsoid to subglobose, (9-)10.5-12(-15) x 5-7 μm, without a distinct perispore. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ red. Chemistry: thallus without lichen substances; apothecia with anthraquinones.
Note: on north-exposed, steep rock faces, from the treeline ecotone to the alpine belt; known from the Tatra mountains, Scandinavia and the Alps, and there so far only recorded from the Eastern Alps (Austria, Germany, Italy), but likely to have been overlooked elsewhere.
