Preliminary phylogenetic analysis targeting internal transcribed spacer (ITS) sequences of the major ribosomal gene of mycorrhizal fungi from mycorrhizal birch root tips revealed three main phylogenetic groups: two Basidiomycetes (Hebeloma and Cortinarius) and one Ascomycetes group, of these Hebeloma and Ascomycetes were more common.
Fyrstu niðurstöður DNA greiningar á ITS svæði svepprótarsveppa sýndu þrjá mismunandi hópa, tvo hópa basíðusveppa, ættkvíslirnar Hebeloma og Cortinarius og einn hóp asksveppa.
