This genome was sequenced as part of the JGI CSP "1000 Fungal Genomes – Deep Sequencing of Ecologically-relevant Dikarya" project. Within the framework of this project, we are sequencing keystone lineages of saprophytic, mycorrhizal, and endophytic fungi that are of special ecological importance. Dozens of sequenced species were harvested from Long Term Observatories to serve as the foundation for a reference database for metagenomics of fungi and for a comprehensive survey of the soil fungal metatranscriptome.

Ceriporia viridans

Ceriporia viridans is a common white-rot polypore of deciduous trees in temperate and boreal Europe. It is found typically on wood in advanced stage of decay in ground contact. Most Ceriporia species produce effused, rather thin, short-lived fruiting bodies, and C. viridans is no exception. For a polypore its fruiting bodies show a remarkable array of colors ranging from white to green, from yellow to purple.

Ceriporia viridans is the type species of the species-rich genus Ceriporia, and belongs to the family Irpicaceae of the order Polyporales (Justo et al. 2017). Within Irpicaceae, it is the first species for which a genome is sequenced in the Ceriporia clade. All Ceriporia species are considered white-rotters, but their close relatives in the small genus Leptoporus (also in the Ceriporia clade) are considered brown-rotters (Ryvarden & Gilbertson 1993). Ceriporia viridans was chosen for sequencing as a representative white-rot fungus and point of comparison with Leptoporus.

The genome strain was collected from a deciduous fallen tree (Betula or Sorbus) in central Finland.
