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.

Piloderma byssinum (Basidiomycota, Atheliales, Atheliaceae) is an ectomycorrhizal fungus, primarily associating with Pinaceae. As a symbiotic fungus, P. byssinum is considered to be important for nutrient acquisition of forest trees, particularly nitrogen acquisition. The fungal mycelium emanating from the mycorrhizal roots is highly developed, consisting of prominent rhizomorphs with a range of interconnected, dense hyphal mats. It is typically encountered in boreal and temperate forests and deviates from the related P. fallax in the brightly white colour of mantles and mycelial cords. P. byssinum seems to be restricted to less disturbed, strongly nutrient limited forests, whereas P. fallax is ubiquitous in a variety of habitats, including young plantations.

The fungal strain used for genome sequencing was isolated by Anna Rosling outside Umeå (Sweden) in 1999.
