Abrothallaceae Lichenoconium lichenicola # Growth type lichenicolous. Identified by Valeriy Darmostuk Photographs on Physcia tenella Commensal or parasitic in the thallus or apothecia of Physcia species. Conidiomata are 100-200 µm diameter and the elongate-ellipsoid to subglobose conidia are simple, light-brown, 8-13 x 2-3.5 µm and +/- slightly warted. Micrographs below. It is possible that forms of Lichenoconium lichenicola on Physcia aipolia may be a different species (with more coarsely verrucose spores). Similar: Lichenodiplis fallaciosa also has simple, light-brown conidia but occurs on Orcularia insperata (Rinodina biloculata)
