Russula vinacea (actual genome source) by Brian P. Looney

This genome was sequenced as part of the JGI CSP "1KFG - Deep Sequencing of Ecologically-relevant Dikarya" and more specifically as a part of the Russulaceae Sequencing Project, which seeks to densely sample members of a diverse lineage of ectomycorrhizal (ECM) fungi to examine functional diversity of ECM fungi with a shared evolutionary history.

Russula vinacea Burl. -- The Blackish-Red Russula

Russula vinacea is a widespread and common species occurring in temperate forests of eastern North America. It is characterized by a vinaceous red to purple cap, usually with a darker disc, white to pale cream spore print, acrid taste, and a stem that turns greyish in age. The species was previously considered as a synonym of Russula bresadolae Schulzer (commonly misnamed as Russula atropurpurea (Krombh.) Britz. nom. illeg and Russula krombholzii Shaffer), a European species mycorrhizal with oak and beech trees, however sequence data supports the validity of R. vinacea as a distinct North American species of Russula subgenus Russula (Looney 2015). Russula bresadolae has been analyzed for its ability to sequester heavy metals, particularly zinc which is stoichiometrically bound by metallothionein-like binding peptides (Leonhardt et al. 2014). Morrison et al. (2016) highlights R. vinacea as a nitrophilic species that became the dominant fungal species with long-term nitrogen addition in an eastern North American experimental hardwood forest. The sporocarps for this genome were collected on July 17, 2015 in a mixed forest with mainly Tsuga canadensis, Carpinus caroliniana, Liriodendron tulipifera, and multiple species of Quercus and Carya in the Elkmont/Sugarlands area of the Great Smoky Mountains National Park. This species is a representative of the type subgenus of Russula and will be important for understanding the evolution of functional diversity of Russulaceae.
