The non-type isolate of Acremonium berkeleyanum CBS 501.81 from Stereum hirsutum was studied under a light microscope and by analysis of three molecular markers (ITS rDNA region, and parts of the LSU rDNA region and elongation factor 1-alpha gene). Phylogenetic analyses placed the strain within Cosmospora lavitskae sensu stricto, where it clustered with the ex-type culture of the species, supporting its identification as C. lavitskae. Based on Cosmospora ITS rDNA sequences collected from GenBank, the substrate range of C. lavitskae is characterised, where strain CBS 501.81 represents the first record of C. lavitskae from Stereum. Teleomorphic and anamorphic characters of C. lavitskae are compared with Sphaerostilbella berkeleyana and its presumed anamorph.
