Abstract
Genetic relationships in a natural Japanese population of Pleurocybella porrigens were determined based on ITS sequence data. In a UPGMA similarity tree, all sequences of 23 specimens from 13 different geographic origins were grouped into two distinct clusters (groups A and B). Sequence variation of the ITS region between groups A and B consisted of 33–40 nucleotides, corresponding to 5%–6% of their total length, and specific nucleotide variations characterizing groups A and B were found. Although these results did not show correlation with differences of substrates for fruiting and geographic origins of the specimens, it was suggested that P. porrigens distributed in Japan include at least two genetically different populations.
