Phylogenetic overview of the tribe Chromosereae inferred from ITS data using ML method. Two Hygrocybe conica sequences were rooted as outgroups. Bootstrap values (≥50%) are shown around the branches. GenBank accession numbers of downloaded sequences were added after the species name and the collection locations were added at the ends. NA, EA and EU referred to North America, East Asia and Europe, respectively. The newly generated sequences are shown in bold.
