General Information and Identification
This is an easy genus of gilled mushrooms to recognize because they all exude a fluid, milky or clear, called a latex, when broken. The latex may be white or colored, and the color may change as the latex dries. This greatly facilities identification.
They're quite similar to the related Russulas, which have no latex, but share all of the other characteristics:
Milky caps all have white gills (which may discolor slightly with age) that attach to the stem (there's no space between the stem and the origin of the gills Amanitas, on the other hand, have free gills). The spore print is white to cream-colored.
There's never a ring or skirt around the stem.
These mushrooms are so brittle that they crumble when handled roughly.
