Rinodina candidogrisea Hafellner, Muggia & Obermayer

Bibl. Lichenol., 108: 80, 2012.
Synonyms: Kudratovia candidogrisea (Hafellner, Muggia & Obermayer) S.Y. Kondr., Lőkös & Hur
Distribution: N - Frl (Hafellner & al. 2012), TAA (Hafellner & al. 2012), Piem (Hafellner & al. 2012).
Description: Thallus crustose, episubstratic, areolate, grey in central parts, white in peripheral parts, forming up to 3 cm wide patches, sorediate. Central areoles angular, contiguous, entirely sorediate, marginal areoles somewhat larger to thinly subsquamulose, with marginal soralia, the soredia grey, granular, 30-55 µm thick, without distinctly protruding hyphae under the dissecting microscope. Medulla white or rarely pale yellow. Apothecia very rare, lecanorine, 0.3-0.7 mm across, with a white-pruinose disc and a thick, pruinose, ecorticate thalline margin. Epithecium brown; hymenium colourless, up to 100 µm high; paraphyses sparingly branched in upper part, c. 2 µm thick at mid-level, with slightly larger apical cells surrounded by a brownish gel and oxalate crystals. Asci 8-spored, cylindrical-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, pigmented, ellipsoid, 23-28 x 10-12.5 µm, Physcia-type, with spore ontogeny of type A (apical wall thickening after septum formation). Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-, UV+ whitish (especially the marginal areoles); medulla sometimes P+ faintly yellow (when white), K+ purple (when yellowish). Chemistry: zeorin and unknown fatty acids (in all samples), sometimes variolaric acid, and an unknown yellow pigment.
Note: a recently-described, ornitocoprophilous, terricolous species growing on mosses and plant debris over calcareous substrata near and above treeline; probably more widespread in the Alps.
Growth form: Crustose
Substrata: soil, terricolous mosses, and plant debris
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
