Russula is a genus of mushrooms, with around 750 worldwide species. They are typically common, fairly large, and brightly colored - making them one of the most recognizable genera among mycologists and mushroom collectors. Their distinguishing characteristics include a white to dark yellow spore print, brittle free white gills, and an absence of partial veil or volva tissue on the stem. The term migrant means it is migratory, referring to Funguars' mobility.
