Anamorph: conidiomata pycnidia, 100-250 (-325) µm diam., subglobose to almost globose, immersed to erumpent from the thallus and/or ascomatal warts of the host lichen, solitary or in groups of 2-3, scattered, appearing black at the surface due to extruded spore masses. Peridium 5-10 µm thick, composed of 2-3 (-4) layers of polyhedral cells, internal cells pale brown, external cells almost hyaline. Conidiogenous cells formed from short branched conidiophores lining the internal wall of the pycnidial cavity, 3.5-10 x 2-3 µm, subcylindrical to ampulliform, annellidic, usually with 1-2 annellations, fuscous brown. Conidia arising singly from the apices of the conidiogenous cells, 3.5-6 x 2.5-3.5 µm, ellipsoidal or ovoid, with a distinctly truncate base, pale brown singly but appearing dark brown in mass, aseptate, smooth-walled, without an epispore, gelatinous sheath or appendages. Teleomorph: not known.
