Cortinarius PSC4653, TAS3

Cortinarius is a large genus of fungi comprising more than 2000 species worldwide, most of which form ectomycorrhizal associations with trees. Cortinarius includes both mushroom-like and truffle-like (sequestrate) species. This lilac-tinted sequestrate Cortinarius, TAS3 PSC4653, was collected in Hellyer Gorge, Tasmania, amongst Eucalyptus obliqua. It is one of at least five lilac-tinted sequestrate species forming a cryptic group and DNA data from old type collections is required to see if any of three available names might be used. Comparison of the genomes of Cortinarius PSC4653 TAS3 with mushroom-like Cortinarius species is anticipated to help understand the transition toward a subterranean lifestyle, which is believed to be an adaptation to a drying climate, a trait with economic potential in future forestry. We request that researchers wishing to publish analyses of this genome prior to its publication by the consortium to please email [email protected] and JGI for permission.
