Studia Geobot.: 64, 2001. Basionym: Calicium mildeanum Hepp in Rabenhorst - Lich. Eur. 718, 1864.
Synonyms: Mycocalicium mildeanum (Hepp) Nádv.; Mycocalicium ornicola (J. Steiner) Nádv.; Stenocybe mildeana (Hepp) Jatta
Distribution: N - TAA (Nascimbene & al. 2007b, Puntillo & Puntillo 2009). C - Marc (Nimis & Tretiach 1999, Puntillo & Puntillo 2009), Umb (Genovesi & al. 2001, Ravera & al. 2006, Puntillo & Puntillo 2009).
Description: Thallus not evident, not lichenized. Apothecia stalked, dark grey to black, up to 0.5 mm high. Stalk brown, reddish in section at least in the outer part, consisting of thick-walled, periclinally arranged hyphae. Capitulum black, epruinose, subglobose, 0.1-0.3 mm across. Exciple of several layers of brown, periclinally arranged, sclerotized hyphae, the inner ones often with an aeruginose tinge; epithecium thin, dark brown; mazaedium absent. Asci 8-spored, narrowly cylindrical, with a strongly thickened apex, formed singly from hooked ascogenous hyphae, with uniseriately arranged ascospores, persisting until the ascospores are mature. Ascospores indistinctly 1(-3)-septate, medium brown, ellipsoid, 13-29 x 7-9 μm. Photobiont absent. Spot tests: not known. Chemistry: probably without lichen substances.
Note: on base-rich bark, mostly of Fraxinus, certainly declining: the record from Marche is the first one from Italy in this century.
