Pleurosticta koflerae (Clauzade & Poelt) Elix & Lumbsch
in Lumbsch & al., Mycotaxon, 33: 453, 1988. Basionym: Parmelia koflerae Clauzade & Poelt - Nova Hedwigia, 3: 368, 1961
Synonyms: Melanelia koflerae (Clauzade & Poelt) Essl.
Distribution:
Description: Thallus foliose, heteromerous, dorsiventral, grey-green (in shade forms), brown or brown-black (in sun-forms), rarely slightly pruinose, usually not forming rosettes, but extensive, confluent swards. Lobes 4-8 mm wide, concave to flat, usually with ascending margins, at first smooth, then undulate-verruculose, often cracked in older parts, sometimes with isidia-like, papilliform to short-cylindrical or finally flattened outgrowths. Lower surface brown-black to black, with black, mostly simple rhizines. Upper cortex paraplectenchymatous, with a pored epicortex, the cell walls containing isolichenan; medulla white; lower cortex paraplectenchymatous. Apothecia very rare, lecanorine. Ascospores not seen. Photobiont chlorococcoid. Spot tests: upper cortex K-, C-, KC-, P-; medulla K+ red to red-brown, C-, KC-, P+ bright yellow. Chemistry: medulla with salazinic acid (major), sometimes with additional norstictic acid and atranorin (traces).
Note: a species with thalli recalling those of a sterile P. acetabulum, but with a different secondary chemistry (major: salazinic acid); rather loosely attached to siliceous rocks, often with a low content in calcium, and there also overgrowing mosses and soil layers; widespread in Eurasia but rare, with two records from the Western Alps (France). To be looked for in Italy
