Abstract
The basidiomycete Craterellus tubaeformis (Fries) Quélet is an important widespread ectomycorrhizal basidiomycete found in the Northern Hemisphere. In this study, 12 samples of C. tubaeformis from North America and Europe were analyzed using internal transcribed spacer (ITS) sequences to reveal the correlation between ITS genotypes and geographic locations and to provide molecular evidence for the identification of C. tubaeformis from different habitats in North America and Europe. The analyses identified abundant sequence variations within C. tubaeformis. The length of the ITS region varied from 571 to 640 bp. The proportion of variable sites was 17.6%, and the proportion of parsimony information sites was 16.7%. Phylogenetic analysis showed some correlations between the ITS genotypes and geographic locations of C. tubaeformis; however, some discrepancies between geographical location and affinity were also found. The results indicated that C. tubaeformis from different habitats in North America and Europe underwent genetic drifting and evolved into 2 different species. nrDNA ITS could be a good markers for distinguishing among C. tubaeformis from different habitats, but rational affinity should be determined by associating the available ITS data with other information sources.
