DNA fingerprints of four wild strains of Auricularia were analyzed by RAPD technique. These four wild strains were grouped into Auricularia polytricha based on the result of RAPD cluster analysis with ten random primers. But they were four distinct strains because there were certain genetic differences among them. The result revealed the phylogenetic relationship and the DNA homogeneity among these four wild strains of Auricularia. And it also provided more important scientific basis for delimiting their t...
