Fruit body production was used to obtain spore prints,monosporic cultures and to evaluate the fructification potential of compatiblecrossings. Protoplast isolation, purification and regeneration were used toattempt obtaining monokaryotic isolates from 2-spored specimens. Mating testsevidenced interfertility of Asian, American and European strains and theintersterility of the Argentinean strain WT-54. These results, in addition tomitochondrial small subunit variable domains phylogeny and morphologicaldata, lead us to consider this strain as a novel species, A. wrightii. TheEuropean, Asian and the rest of the American strains belong to A. cylindracea.The concept of A. cylindracea sensu lato includes at least two different species:A. cylindracea and A. wrightii.
