The scattered or clustered small black pycnidia are subglobose to broadly ovoid, immersed or erumpent. Brown to dark-brown conidia are (2.5-)3-4.5(-5.5) µm diameter, subglobose to broadly ellipsoidal, +/- truncate at base and slightly verruculose. Micrographs below Most frequent on Lecanora species but commensalistic to parasitic on the thalli and apothecia of a wide range of foliose and crustose lichens, mainly from the Lecanoraceae and Parmeliaceae. Often found with Lichenoconium erodens Similar: Lichenoconium usneae, conidia not truncate at base. Often with other lichenicolous fungi on foliose and fruticose lichens
