Relationship among Collybia s. str. in Greenland, North America and Eurasia
Collections of Collybia s. str. from Greenland were analyzed morphologically and by DNA sequencing of the nuclear ribosomal ITS1-5.8S-ITS2 region. Results confirmed that all three species of Collybia were present and sympatric in Greenland. Collybia tuberosa ITS sequences of collections from Greenla...
