The new lichenicolous species Trichoconis hafellneri, growing on Athallia pyracea and Xanthoria parietina, is described, illustrated and compared with lichenicolous and other species hitherto assigned to Trichoconis. This is followed by a brief discussion on the current circumscription of that genus, supplemented by keys to the accepted species of Trichoconis.
