Abstract Recently published taxonomic circumscriptions for taxa withinFlammulina encouraged mating studies to confirm or reject these names or taxa. Three categories of pairing experiments were performed: 1) self-crosses of monokaryon isolates of examplars of various putative taxa; 2) inter-exemplar pairings among exemplar strains; and 3) pairings between examplars and 87 unidentified strains which were grouped on this basis. Mating experiments could distin-guishF. velutipes from other taxa, but not among infraspecific taxa ofF. velutipes (vars.velutipes, lactea, andlupinicola) and monokaryons of all these taxa were partially compatible with those ofF. ononidis. Likewise, isolates ofF. rossica andF. elastica were partially compatible with one another but incompatible with those of other taxa. All other taxa (F. mexicana, F. stratosa, F. populicola, F. fennae) appeared to be genetically isolated. Low levels of interspecific hybridization betweenF. velutipes andF. populicola, and betweenF. velutipes andF. rossica/elastica were also noted.
