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.

Intextomyces contiguus

Intextomyces contiguus is a corticioid fungus with white, effused fruiting bodies. Although it has been reported from various tree species, it is typically found on bark of living or recently dead, old willow trees in old-growth forests (Eriksson & Ryvarden 1976). The species has a northern distribution in Europe, and is widely distributed in boreal Eurasia and North America. Due to habitat loss it has been classified as Near Threatened (NT) in the national Red Lists of Finland and Norway.

Intextomyces contiguus is the type species of the genus Intextomyces. The genus belongs to the class Agaricomycetes, but which order within that class is unclear, since it has no close relatives. The genome will help to classify it properly and to resolve phylogenetic relationships within the Agaricomycetes more broadly. The genome will also help to answer if this species is a wood decomposer - it evidently has saprotrophic ability, but it is unclear if it degrades wood or just bark or if it is parasitic.

The genome was produced from a polysporic culture originating in Kainuu, Central Finland, where the fungus grew on living goat willow (Salix caprea) in an old-growth forest.
