Syncesia myrticola (Fée) Tehler

Fl. Neotrop. Monogr., 75: 18, 1997. Basionym: Chiodecton myrticola Fée - Essai Cryptog. Ecorc. Offic., 1: 63, 1824.
Synonyms: Chiodecton albidum (Taylor) Leight.; Chiodecton petraeum Delise; Enterographa sorediata Coppins & P.James; Syncesia albida Taylor
Distribution: N - Lig. C - Tosc, Sar (Sundin & Tehler 1998). S - Si (Nimis & al. 1994, Ottonello & Romano 1997, Ottonello & al. 2011).
Description: Thallus crustose, episubstratic, continuous and smooth to folded-nodulose, chalky white to pale grey, water-repellent, usually esorediate, rarely sterile and with orbicular, c. 0.5 mm wide, finally sometimes confluent, grey-white soralia bearing farinose soredia (never observed in Italian material), sometimes delimited by a dark prothallus. Apothecia 0.1-0.2 mm wide, brown to black, but often white-pruinose, punctiform, circular, lirelliform or star-shaped, often confluent, immersed in raised, basally constricted, rounded to oval, 1-4 mm wide stromata with 5-15 apothecia. Exciple level with disc, of richly branched, interwoven, hyaline hyphae, with crystals dissolving in K; epithecium dark brown; hymenium colourless, 70-90 μm high, I+ blue; pseudoparaphyses sparingly branched, coherent in water but easily separable in K; hypothecium carbonaceous, K+ olive-black. Asci 8-spored, clavate, fissitunicate, thickened at apex, with an internal K/I+ blue ring. Ascospores 3-septate, hyaline, narrowly fusiform, straight or curved, 35-44 x 4-5 μm. Pycnidia brown to black. Conidia filiform, straight to curved. Photobiont trentepohlioid. Spot tests: thallus K-, C-, KC-, P+ rust-red, UV+ cream-coloured. Chemistry: protocetraric and roccellic acids.
Note: a humid subtropical to Mediterranean-Atlantic lichen found on bark and base-rich siliceous rocks in the most humid parts of Tyrrhenian Italy, usually in the Mediterranean belt and not far from the sea, sometimes lichenicolous on Dirina-species. Sterile, sorediate, often epiphytic forms corresponding with Enterographa sorediata were never found in Italy but should be looked for in the most humid parts of Tyrrhenian Italy.
