What specific type of fungus inhabits the tundra?

Please include both the common and scientific names. I know that they exist in the tundra because they partially form lichens.. but I need the specific species of fungus so that I can include them as decomposers in the tundra food web I need to write.What specific type of fungus inhabits the tundra?
The Mycobiont: The fungal mutualist may belong to one of over 500 genera and over 13,500 species of lichen-forming fungi ---about 20% of known fungal species Although a few are Basidiomycota (about 20 species) or deuteromycetes, most are Ascomycota, coming from 16 orders, 5 of which are entirely composed of lichen-forming fungi. Lichenized and non-lichenized fungi may occur in the same order. Taxonomically, the lichenized fungi are widely distributed in the Ascomycota. It is not known whether the fungal partners have an extensive independent existence in nature.
