Athallia saxifragarum (Poelt) Arup, Frödén & Søchting

in Arup & al., Nord. J. Bot., 31: 36, 2013. Basionym: Caloplaca saxifragarum Poelt - Feddes Rep., 58: 176, 1955.

Synonyms: Callopisma luteoalbum f. microcarpum (Anzi) Arnold; Caloplaca pyracea var. microcarpa (Anzi) Dalla Torre & Sarnth.; Caloplaca schoeferi Poelt; Placodium luteoalbum f. microcarpum Anzi

Description: Thallus crustose, usually thin and continuous, sometimes almost endosubstratic, pale grey to almost white, very rarely yellowish white, forming 0.5-2 cm wide patches. Cortex usually poorly developed, of an amorphous layer or indistinctly paraplectenchymatous; medulla poorly developed. Apothecia frequent, zeorine, scattered to crowded, adnate to sessile, 0.3-1 mm across, with a flat to slightly convex, bright orange to yellow-orange disc, a thick, yellow-orange (often slightly paler than disc) proper margin, and a poorly developed, greyish to yellowish grey thalline margin, which is often visible only on the underside of young apothecia. Proper exciple of irregularly radiating, thick-walled hyphae; epithecium orange, granular, K+ purple-red, C-; hymenium colourless, 70-90(-100) μm high, amyloid; paraphyses (1-)2-2.5 μm thick at mid-level, the apical cells (2-)4-6 μm wide; hypothecium colourless, sometimes inspersed with oil droplets. Asci 8-spored, cylindrical-clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid to broadly ellipsoid, (8.5-)10-14(-15) x (4.5-)6-8(-10) μm, the equatorial thickening (“septum”) (3-)4-5.5(-7.5) μm, c. 1/3-1/2 of spore length. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ purple-red, C-. Chemistry: thallus without lichen substances; apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor), corresponding with chemosyndrome A of Søchting (1997).
