in Baruffo & al., Nova Hedwigia, 83: 390, 2006. Basionym: Crocynia alpina B. de Lesd. - Bull. Soc. Bot. France, 61: 85, 1914.
Synonyms: Crocynia antarctica Hue; Crocynia caerulescens Hue; Crocynia candidissima Hue; Crocynia minima Hue; Lepraria angardiana Øvstedal; Lepraria cacuminum (A. Massal.) Loht.; Leproloma angardianum (Øvstedal) J.R. Laundon; Leproloma cacuminum (A. Massal.) J.R. Laundon
Description: Thallus crustose to subleprose, whitish to whitish grey, up to 0.7 mm thick, entirely consisting in a mass of granules, usually well-delimited, sometimes indistinctly sublobate at margin, forming up to 10 cm wide patches (usually less). The thallus starts developing as isolated, dispersed granules that form piles or aggregations (best visible along the margins, where the dispersion of the young granules is most readily observed), which eventually overlap and become confluent, giving the false appearance of a continuous thallus in older areas. Granules rather firmly attached, coarse, 80-150 μm in diam., sometimes gathered into 200-300 μm wide aggregates, with a well-developed pseudocortex, the surface appearing compact, rarely with very short projecting hyphae; Medulla white and cottony, rather thin (0.3-0.5 mm), often partially exposed. Photobiont chlorococcoid. Spot tests: K- or K+ yellow, C-, KC-, P- or P+ faintly yellow, UV-. Chemistry: atranorin, porphyrilic acid and a fatty acid (roccellic/angardianic or rarely rangiformic acid); very rarely fatty acids and/or atranorin can be absent.
