However, the

morphological resemblance has caused much confusion and isolates are often misidentified or not differentiated by taxonomists using morphological and physiological techniques (Pitt et al. 1990). Mocetinostat sixty-nine strains originating from cork and belonging to the Glabra series were grouped according to their partial β-tubulin gene sequences. A subset of these strains was selected for macro- and microscopic analysis, extrolite profiling and sequencing a part of the β-tubulin and calmodulin gene. In addition, check details ex-type strains of various related species were included in the analysis. Our polyphasic taxonomic approach shows that a group of isolates share peculiar differences with other known species, and a new species is proposed for this group of isolates. Materials and methods Fungal strains For our taxonomic study, a selection of these sixty-nine

strains isolated from cork, was made and supplemented with related (ex-type) strains (Table 1). Spore suspensions of the cultures were maintained in 20% glycerol at −80°C.
