Abstract


Background:A previously identified sample XC02, which was collected from a pine forest (Pinus kesiyaRoyle ex Gordon), in Xuan Tho Commune, Da Lat, Lam Dong Province, Vietnam, was identified asCantharellus minorbased on morphology andnrLSUphylogeny analysis. Sequence analysis ofmultiple genesare becoming more and more common for phylogenetic analysis of mushrooms.

Method:Total DNA was isolated from sample XC02. The primer NS1, NS4 were applied to amplify the target genethe nuclear ribosomal small subunitDNA(nrSSU). For phylogenetic analysis, individual and concatenateddatasets (nrSSUandnrLSU-nrSSU) were constructed. Phylogenetic tree was constructed with MEGA 6.0 with a 1000 replicate bootstrap based on the neighbor joining, maximum likelihood, maximum parsimony method.

Results:A concatenateddataset containing a total of 14 sequences fromCantharellus,Craterellus (Cantharellaceae,Canthraellales)andHydnum(Hydnaceae,Cantharellales) were constructed. For the specimen XC02, the phylogenies based on the first, second, and third datasets (nrLSU,nrSSU, andnrLSU-nrSSU) and the morphological analysis, reported in our previous study, strongly confirmed the identity of XC02 asCantharellus minor.

Conclusion:The combination between the morphological analysis and phylogenetic analysis is confirmed as the best approach for the identification ofCantharellusand other mushroom species that we collected in the Central Highlands, Vietnam.
