Abstract
The base composition of DNA (GC content) of 25 strains, morphologically referred to the genusHumicola Traaen, is studied. The range of GC% variation is about 23 % (from 28,5 % to 51,6). Two prominent groups of strains with similar GC content may be distinguished: one ranging from 28 % to 37 % and the other ranging from 40 % to 49 %. The aleuriospore size is not related to the DNA base composition, but a group of strains with prevalently coloured hyphae, with aleuriospores of similar size and with high GC content is recognized. Several previous literature reports on the taxonomy ofHumicola are discussed.
