Mém. Soc. Imp. Sc. Nat. Cherbourg, 5: 334, 1858.
Synonyms: Calicium microscopicum (Anzi) Jatta; Phacotiella microcephala (Sm.) Vain.; Sphinctrina microscopica Anzi; Sphinctrina pinicola Körb.
Description: Thallus not evident, not lichenized. Apothecia short-stalked, 0.2-0.45 mm high, black or rarely dark brown. Stalk of periclinally arranged hyphae with strongly gelatinized walls, pale in inner part, dark brown to reddish brown in outermost part, which consists of a layer of isodiametric, sclerotized cells. Capitulum spherical to irregular, 0.1-0.2(-0.3) mm across, shiny black; mazaedium well-developed, black. Exciple well-developed, dull brown, the upper part of more or less isodiametric, periclinally arranged hyphae, the lower part of sclerotized cells; hypothecium colourless to pale brown, 40-50 µm high. Asci 8-spored, cylindrical, formed singly from ascogenous hyphae with croziers, with a single, functional wall layer, K/I-, disintegrating at a rather late stage, with uniseriately arranged spores. Ascospores 1-celled, subglobose, dark brown, 7-10 x 7-9(-10) µm, with a minutely dotted wall. Photobiont absent. Spot tests: all parts of ascomata K-, C-, KC-, P-. Chemistry: without lichen substances.
