Modern occurence: Kretzschmaria (syn. Ustulina) species are found worldwide throughout temperate and tropical regions and occur on plant debris and dead wood (Rogers and Ju, 1998). Only two distinct species, Kretzschmaria clavus and Kretzschmaria cetrarioides, seem to be distributed in tropical Africa (Dennis, 1961).
