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

Boletus coccyginus Thiers – Sumac-colored bolete

BoletusHortiboletuscoccyginus is considered a rare species known from California and Oregon in mixed forests under Douglas-fir, Tanoak, and Coast Live Oak. The species is characterized by small size (2-8 cm cap width), red cap, yellow pores that discolors bluish-green with age, red hue on stipe, and variable spore size and shape. Phylogenetically, this species is closely related to members of the genus Hortiboletus in the Boletaceae. The genome isolate was derived from sporocarps found fruiting under Populus trichocarpa on October 26, 2016 in Sandy Creek Delta Park, Troutdale, Oregon. Boletus coccyginus 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.
