Phyllopsora rosei Coppins & P. James

Lichenologist, 11: 166, 1979.
Synonyms:
Distribution: S - Cal (Puntillo 1996).
Description: Thallus crustose to minutely squamulose, esorediate, glaucous grey when dry, emerald green when wet, consisting of small granules in central parts, of minute squamules in peripheral parts, the whole forming an up to 5(-7) cm wide crust. Squamules at first granulose and 50-150 μm wide, then, especially in marginal parts, flattened, crenate to finger-like, 0.15-0.3 mm wide, weakly corticated, finely tomentose; prothallus whitish, cottony, sometimes obscured. Apothecia rather rare, biatorine, 0.3-1.5 mm across, often clustered, with a flat to convex or often tuberculate, pale orange- to deep red-brown, epruinose disc and a very thin and inconspicuous, concolorous or paler proper margin. Proper exciple colourless or red-brown, of radially oriented, thick-walled, gelatinized hyphae; epithecium poorly differentiated, colourless or brownish; hymenium colourless, 20–30 μm high; paraphyses mostly simple, 2–3 μm thick at mid-level, the apical cell not swollen; hypothecium thick, 200–230 μm high, colourless or red-brown in parts. Asci 8-spored, clavate, surrounded by a gelatinous I+ blue coat, with a well-developed I+ blue tholus with a I+ darker blue tube and a well-developed ocular chamber, Bacidia-type. Ascospores simple or thinly 1(-3)-septate, hyaline, narrowly ellipsoid to short-fusiform, (7-)10-13(-15) x 2-3(-4) μm. Photobiont chlorococcoid. Spot tests: thallus K- or K+ faintly yellow, C-, KC-, P+ orange-red. Chemistry: thallus with argopsin.
Note: a rare western European epiphytic species with humid subtropical affinities; the single Italian collection is from the acid bark of Pinus leucodermis. It is included as “Critically Endangered” in the Italian red list of epiphytic lichens (Nascimbene & al. 2013c).
