Lactarius
Like the closely related genus "Russula", their flesh has a distinctive brittle consistency. It is a large genus with over 500 known species, mainly distributed in the Northern hemisphere. Recently, the genus "Lactifluus" has been separated from "Lactarius" based on molecular phylogenetic evidence.
what species is lactifluus volemus? It is a species of fungus in the family Russulaceae. who was the first to name and describe it? The first mention of "Lactifluus volemus" in the scientific literature was in Carl Linnaeus's 1753 "Species Plantarum", under the name "Agaricus lactifluus". can this be consumed by humans?

Like the closely related genus "Russula", their flesh has a distinctive brittle consistency. It is a large genus with over 500 known species, mainly distributed in the Northern hemisphere. Recently, the genus "Lactifluus" has been separated from "Lactarius" based on molecular phylogenetic evidence.
