Description: Thallus not evident, not lichenized. Apothecia sessile, globose or vertically compressed, shiny black or rarely dark brown, (0.2-)0.3-0.4 mm across, 0.1-0.4 mm high, usually with a colourless excipular rim caused by loosely interwoven, hyaline hyphae protruding beyond the coloured tissues; mazaedium well-developed, black. Exciple with an outer scleroplectenchymatous layer consisting of isodiametric to ovoid cells with thick gelatinous walls, reddish brown to pale brown, almost hyaline inside, the inner layer prosoplectenchymatous, of periclinally arranged hyphae; hypothecium medium to pale brown, of thin-walled cells. 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, dark brown, subglobose to broadly ellipsoid, (8-)9-12(-14) x (6.5-)7.5-9.5(-10) µm, with an indistinct gelatinous coat, and a poorly evident ornamentation. Photobiont absent. Spot tests: K-, C-, KC-, P-, except the reddish brown parts of the ascomata, which react K+ intensifying red-brown. Chemistry: without lichen substances.
Note: a non-lichenized lichenicolous fungus growing on the thalli of Pertusaria paramerae, known from the Iberian and Balkan Peninsulas, Morocco, Libya, and Turkey. To be looked for in Italy.
