Description: Thallus inapparent, not lichenized, developing on the thalli of Bagliettoa- and Verrucaria-species. Apothecia at first isodiametric and resembling perithecia, then more or less elongate, black, epruinose, 0.2-1 x 0.2-0.3 mm, raised, often gathered in small clusters, with a slit-like disc and a black margin. Proper exciple black, carbonaceous, usually not extending below the hymenium, K- or K+ red-brown; epithecium brown, K-; hymenium colourless, K/I+ blue, the upper part brownish and I+ blue, the lower part I+ reddish; hypothecium colourless to yellowish brown. Asci 8-spored, broadly clavate, Opegrapha-type. Ascospores 3-septate, hyaline (finally often brownish and with a verruculose surface), 13-23(-25) x (4-)5-7(-8) μm, with a distinct perispore. Pycnidia more or less immersed, black. Conidia 3-5 x 0.5-1.2 µm. Photobiont: absent. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: an ecologically wide-ranging lichenicolous fungus found both in natural habitats (especially shaded niches of calcareous rocks in woodlands), and in moderately disturbed situations (such as on north-facing walls), growing on crustose lichens (especially Bagliettoa and Verrucaria-species).
