| phylogenetic species delimitation in ectomycorrhizal fungi and implications for barcoding: the case of the tricholoma scalpturatum complex (basidiomycota). | population studies have revealed that the fungal ectomycorrhizal morphospecies tricholoma scalpturatum consists of at least two genetically distinct groups that occur sympatrically in several geographical areas. this discovery prompted us to examine species boundaries and relationships between members formerly assigned to t. scalpturatum and allied taxa using phylogenetic analyses. sequence data were obtained from three nuclear dna regions [internal transcribed spacer (its), gpd and tef], from 1 ... | 2010 | 21044190 |
