Anamorph: conidiomata ca 150 µm diam., in small clusters, erumpent through the host thallus, globose to subglobose, ostiolate with a small opening and minutely papillate, dark brown to black. Conidiomatal wall dark brown throughout, 10–15 μm thick, composed of 3–5 layers of thick-walled angular flattened cells. Conidiophores absent. Conidiogenous cells 7-10 x 2.5-3.5 µm, narrowly conical to ampulliform, mostly proliferating percurrently with small collarettes but with a few appearing annellidic. Conidia 4.5–5.8 × 1.8–2.1 μm, ellipsoidal or fusiform-ellipsoidal, hyaline, quite thin-walled, smooth, without an perispore or appendages. Teleomorph: not known.
