Within the framework of the JGI Mycorrhizal Genomics Initiative and the 1000 Fungal Genomes project, we are sequencing a phylogenetically and ecologically diverse suite of mycorrhizal fungi (Basidiomycota, Ascomycota and Glomeromycotina). This comparative genomics resource provides a much-needed boost for the research community to understand the evolution of mycorrhizal symbioses.
Russula emetica (Schaeff.) Pers. – Sickener
Russula emetica, commonly known as the sickener, emetic russula, or vomiting russula, is an ectomycorrhizal basidiomycete mushroom, and the type species of the genus Russula. It has a red, convex to flat cap up to 8.5 cm in diameter, with a cuticle that can be peeled off almost to the centre. The gills are white to pale cream, and closely spaced. A smooth white stem measures up to 10.5 cm long and 2.4 cm thick. The mushroom has a wide distribution in the Northern Hemisphere, where it grows on the ground in damp woodlands in an ectomycorrhizal symbiosis with conifers, especially pines. This strain has been sampled in Duke forest in the U.S.A. by Dr. Brian Looney. Another strain of R. emetica sampled in a mountainous coniferous forest in the Bohemian Forest, Central Europe, has already been sequenced by JGI (https://mycocosm.jgi.doe.gov/Ruseme1/).
