Lichenoconium erodens  

Anamorph: conidiomata pycnidia, minute, (20-) 30-50 (-60) µm diam., scattered, immersed but becoming erumpent at the apices or ± superficial, subglobose, black, opening by an irregular pore. Conidiomatal wall composed of 1-3 layers of polyhedral to rounded cells, mainly 3- 5 µm diam., dark brown and thick-walled. Conidiogenous cells lining the internal wall of the pycnidial cavity, (3.5-) 4-5 (-6) x (2-) 3-3.5 (-4) µm, shortly ± cylindrical to ampulliform, proliferating percurrently or with a single annellation. Conidia 2-3.5 (-4) µm, subglobose to somewhat polyhedral, not markedly truncated at the base, brown, ± smooth to verruculose.
Teleomorph: not known.
