The new genus Reichlingia is described for a lichenicolous dematiateous hyphomycete with non-stromatic conidiophores forming sporodochia or becoming confluent, and dark brown, septate, branched, verrucose conidia. The single species, R. leopoldii, appears to be common in Central Europe, where it always grows on an unidentified, perhaps even undescribed, sorediate lichen species with Trentepohlia as a photobiont, which develops on bark or on sandstone rocks.
