Key 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.
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
Dull-colored Lactarius Section
Cap brown to light brown or greyish, sometimes with lilac tinges or spotted; often fading to buff; not scrobiculate, often umbonate
Fragrant Lactarius SubSection
Fruiting body with a smell, either a so-called maple syrup-fenugreek smell, or one resembling the smell of drying latex paint
Latex clear or white, often scanty
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.
- Cap up to 4 1/2" across; purplish brown when very young, fading to reddish and then pinkish brown; staining pale olive in KOH
Taste slowly and mildly acrid
Spore print pinkish buff
Without microscope work, this point in the key represents a species complex:
In Lactarius quietus the pileipellis is an oedotrichodermium. The very similar L. frustratus has an ixocutis with free hyphal ends projecting above the slime layer
