Slimy Lactarius     Subgenus

Cortinarius husseyiKey to Gilled Mushrooms     Key
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.

Russula paludosaRussulales     Suborder
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

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