Description : Flora (1985: 212–213 – as Lecanora blanda; 219 – as Lecanora subglaucodea). See also Dickhäuser et al. (1995: 308), and Lumbsch & Elix (2004: 31–32).

Chemistry : Thallus K+ yellow. Major compounds: atranorin, ±norstictic and ±protocetraric acids; minor compounds: chloroatranorin, connorstictic, ±norstictic, ±protocetraric and salazinic acids (Dickhäuser et al. 1995).

N: Wellington. S: Marlborough (Mt Stokes, Ship Cove), Canterbury (Cass, Arthur's Pass, Lake Taylor, Lees Valley, Mt Palm, Lowry Peaks Ra., Torlesse Ra., Banks Peninsula, Mt Peel, Black Forest Road Lake Benmore, Hakataramea Valley), Otago (Timaru Creek, Lake Hawea, Damper Bay, Lake Wanaka, Queenstown, Pisa Ra., Dunstan Mts, Old Man Ra., Butcher's Dam near Alexandra, Poolburn Reservoir, Kyeburn, Horse Ra., Lamb Hill, Mt Watkin, Maungatua, Lee Stream, Mt Cargill, Abbott's Hill). On subalpine to alpine rocks in both full sun and in semi-shade – often the most common "white-paint" lichen found on rocks in subalpine and alpine grassland, making rocks appear at a distance to be spattered with white paint. Also in Australia, North and South America, East and South Africa (Imshaug & Brodo 1966; Dickhäuser et al. 1995; Becker 2002; Lumbsch & Elix 2004; Ryan et al. 2004b: 217).

Lecanora farinacea (a member of the Lecanora subcarnea -group) is characterised by: the saxicolous habit; the whitish to grey-white thallus, the presence of the norstictic acid chemosyndrome in addition to protocetraric acid, and by the relatively large spores. In addition, it can be distinguished from most similar species by the presence of an amphithecial cortex where the cortical crystals do not dissolve in K. Slightly pruinose morphodemes of L. farinacea may be similar to the neotropical taxon L. glaucodea Nyl. (Feige et al. 2000: 100), but are distinguished by the presence of depsidones (norstictic and protocetraric acids), small crystals in the amphithecium, and broader ascospores.
