Russulaceae
Russulaceae is a family of fungi in the order Russulales. Its species have typically friable, chalk-like stalks, that break with a distinct crack, like a carrot but with porous flesh.
The family is dominated by just two well-known genera:
* The genus Russula
* The genus Lactarius, or Milk-caps -
Genus Russula
Russula is a large genus of chalky-brittle ectomycorrhizal mushrooms. Principle characteristics include:
* Spore deposit white, cream, yellowish, to ochre
* Lamellae attached, white to yellowish

* Flesh with clusters of sphaerocysts
* Spores with an amyloid ornamentation of warts, ridges, or reticulations -

Genus Lactarius
Lactarius is a large genus of mycorrhizal mushrooms that exude a "latex," or milk, when injured. In some species the milk is copious, and it almost seems to pour out of the mushroom when you slice it or damage the gills. In other species the milk can be scanty to almost nonexistent in older specimens that have grown in dry weather.
