Description: Thallus not evident, not lichenized. Apothecia short-stalked, 0.15-0.36 mm high, or subsessile and partially immersed in the host thallus. Stalk black or dark brown, of irregularly interwoven hyphae, pale in inner part, dark brown to reddish in outermost part (section). Capitulum subglobose to obovoid, 0.14-0.26 mm across, shining black or dark brown; mazaedium well-developed, black. Exciple well-developed, with an inner layer of poorly sclerotized, dark to reddish brown, periclinally arranged hyphae and outer layer of anticlinally arranged hyphae; hypothecium colourless. 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, subfusiform, with pointed ends, dark brown, (9-)10-15(-19) x (4.5-)6.5-8(-9) µm, with an ornamentation of longitudinally arranged, coarse ridges. Photobiont absent. Spot tests: all parts of the ascomata K-, C-, KC-, P-. Chemistry: without lichen substances.
Note: a parasite on the thalli of crustose lichens, mostly Pertusaria leioplaca. Widespread throughout the country, but not common.
Growth form: Lichenicolous fungus
Substrata: bark
Reproductive strategy: mainly sexual
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
