Synonyms: Arthopyrenia rhyponta (Ach.) A. Massal.; Arthopyrenia rhyponta f. tiliaecola Anzi ex Garov.; Leiophloea rhyponta (Ach.) Trevis.; Pyrenula rhyponta (Ah.) Trevis.
Distribution: N - Frl (TSB 2226), Ven, TAA (Thor & Nascimbene 2007, Nascimbene & al. 2007b), Lomb, Piem (Isocrono & al. 2004). C - Abr (Nimis & Tretiach 1999), Mol (Nimis & Tretiach 1999, Caporale & al. 2008). S - Cal (Puntillo 1996).
Description: Thallus crustose, thinly episubstratic, continuous to rimose, dark grey to black due to the presence of abundant dark brown hyphae, sometimes reduced and visible only around the perithecia, probably not lichenized. Perithecia black, hemispherical, partly immersed in the substratum, 0.1-0.3 mm across. Involucrellum dimidiate, black, K-; exciple colourless; hamathecium of unbranched, not anastomosing, up to c. 3 µm thick, often slightly moniliform, soon gelatinized pseudoparaphyses. Asci 8-spored, obpyriform-clavate, thick-walled and fissitunicate, with an elongate apical channel but no well-defined ocular chamber, (37-)50-75 x 15-19 µm. Ascospores persistently 3-septate, hyaline but becoming brown when overmature, oblong-clavate, (14-)16-22(-25) x (4-)5-8(-9) µm, often breaking into part spores, with a 1.5-3 µm wide gelatinous sheath. Pycnidia black. Conidia bacilliform, 4-5 µm long. Photobiont absent. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: a probably circumpolar species found on smooth bark, especially on twigs and branches of deciduous trees, most common in upland areas (especially in Southern Italy); probably non-lichenised.
