Gomphillus calycioides (Duby) Nyl.

Mém. Soc. Sc. Nat. Cherbourg, 2: 15, 1853. Basionym: Baeomyces calycioides Delise ex Duby - Bot. Gallic., 2: 636, 1830.
Synonyms: Berengeria calicioides (Duby) A. Massal.; Mycetodium calicioides (Duby) A. Massal.
Distribution: N - Ven (Nascimbene & Marini 2010), Lomb, Piem.
Description: Thallus crustose, thin, membranous, pale grey to greenish, often poorly evident, the hyphae penetrating the cells of moss and liverwort leaflets. Apothecia borne on short-stalks which are black in upper part, paler in lower part, solitary or clustered, 0.2-0.7 mm across, with a convex, dark brown to black disc. Exciple well-developed, extending below into the stalk, pale brown in upper and outer part, almost colourless within; epithecium reddish brown; hymenium colourless; paraphyses thin, anastomosing, the apices not swollen. Asci 8-spored, narrowly cylindrical, with a non-amyloid apical tholus. Ascospores many-septate (with up to 100 septa), with almost square cells, hyaline, thread-like, 160-200 x 1.5 2(-3) µm, with rounded apices. Pycnidia black in upper part, pale below. Conidia ellipsoid, 2-4 x 0.5-0.7 µm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K-, C-, KC-, P-. Chemistry: without lichen substances.
Note: a mild-temperate to tropical species found on bryophytes, mostly on basal parts of old trunks in mature warm-humid forests at low elevations. The regions from which it was reported, mostly in the Insubrian district of Italy, are presently affected by air pollution, so that the species was included as “Regionally Exctinct” in the Italian red list of epiphytic lichens (Nascimbene & al. 2013c).
