Russulaceae is a family of fungi commonly known as the russulas and lactarias. This family includes a variety of mushroom species, many of which are found in forests and woodlands. They are characterized by their gilled caps and can be either edible or toxic, making identification important for foragers. Members of the Russulaceae family typically have a firm, brittle texture and come in various colors. The two main genera within this family are Russula and Lactarius. While Russula mushrooms often have a smooth cap, Lactarius species are known for their milky latex, which can ooze from cuts in the flesh.
