TL;DR: Three haplotypes of E velutipes were identified with geographical distributions chief- ly in Asia, Europe and North America and recent trans- fer of haplotypes among geographical areas seems plausible based on the observed haplotype distribu- tion.
Abstract: Representative collections of Flammulina were examined by restriction digests of the ribosomal RNA internally transcribed spacer region (ITS1-5.8S- ITS2). Digestion with the restriction enzymes, HaeIII and Bst F51 distinguished among the major North- ern Hemisphere species of Flammulina. Digestion of E velutipes collections with two additional restriction enzymes, Bgl I and Bst UI, gave variable restriction fragment patterns and revealed biogeographically identifiable patterns. Three haplotypes of E velutipes were identified with geographical distributions chief- ly in Asia, Europe and North America. Recent trans- fer of haplotypes among geographical areas seems plausible based on the observed haplotype distribu- tion.
