We determined the DNA sequences of the internal transcribed spacer 1 and 2 (ITS 1 and 2), the 5.8S rRNA gene and most of the 28S rRNA gene of Poria cocos for the first time, and conducted analysis of 20 samples including cultured mycelias and crude drug materials obtained from various localities and markets. Direct sequencing of the ITS 1 and 2 regions of the samples, except for four wild samples, showed that...
