Lactarius uvidus

This is a key to gilled mushrooms, that is, mushrooms having a definite cap with a fertile surface consisting of gills. The fruiting body usually also has a stem, although that may be lateral or absent (usually, then, the mushroom is growing from wood). You can use this key to identify mushrooms that you find.

Flesh without fibers, fracturing with the same sort of break as a piece of chalk
Spore and gill color limited to white, yellow, or ochre
Mycorrhizal: occuring only on the ground, and only when there are trees nearby
No ring or volva on stalk
All fleshy-stemmed mushrooms whose gills exude a latex when cut go here

Fruiting bodies (especially the gills) exuding a liquid (called a latex) when broken
Stalk (and sometimes even gills) usually concolorous with cap

Slimy Lactarius     Subgenus Cap sticky or slimy when fresh

Links from Look-alikes Peppery Lactarius     Subgenus Latex white, abundant in fresh specimens, extremely acrid Cap up to 10" across; white to buff, sometimes with tinges of other colors Gills sometimes extremely close

Lactarius uvidus     (Fries) Fries

Here are the characters that distinguish this species from the others in its group. For its more general characters, see higher up on the page.
If there's just a few words or a microscopic feature here, a more thorough description can be found above.

Diagnosis

• Cap up to 4" across; various dull, whitish shades of lilac and brown; darkening with age; turning green with KOH
  
• Latex white, becoming dingy cream, and staining broken surfaces dull lilac
