In the “1KFG: Deep Sequencing of Ecologically-relevant Dikarya” project (CSP1974), we aim to sequence additional sampling of genomic diversity within keystone lineages of plant-interacting fungi and saprophytic fungi that are of special ecological importance for understanding terrestrial ecosystems. In addition, comparative genome analysis with saprotrophic, mycorrhizal and pathogenic fungi will provide new insights into the specific and conserved adaptations associated with each fungal lifestyle.

Tricholoma populinum J.E. Lange – Poplar tricholoma

Tricholoma populinum J.E. Lange is considered a widespread species, occurring across the Holarctic, and has a strict host preference for ectomycorrhizal members of Salicaceae. The species is characterized by viscid, pinkish brown to reddish brown cap, whitish gills that stain reddish prown, and a strong farinaceous odor and taste. Phylogenetic evidence shows that North American collections of this species are genetically divergent and may constitute a separate species. The genome isolate was derived from a tissue culture derived of sporocarps found fruiting under Populus trichocarpa on Oct 25, 2016 in a planted grove of Populus trichocarpa, Corvallis, Oregon. Tricholoma populinum is a core member of the Populus trichocarpa ectomycorrhizal community and will be an important tool for understanding community assembly and function of the Populus root microbiome.
