Armillaria luteo-virens is a ectomycorrhizal fungus symbiotic with some species of Kobresia in Tibet Plateau, China. A strain was recently isolated from fruitbody tissue of the fungus. To determine whether the strain is the pure culture of the fungus, the internal transcribed spacer region and the first intergenic spacer region (IGS-1) of the nuclear ribosomal DNA of fruiting body and the isolated strain were sequenced and compared. Further, the 5.8S/ITS and IGS-1 sequences of the species were BLAST matched with GenBank database on homology and a phylogenetic tree was constructed based on 5.8S/ITS sequence and two phylogenetic trees were constructed separately based on two IGS-1 sequences.
