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.

Cap slimy, deliquescing in maturity; striate, at least in maturity
Cap fragile, hollow

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 2 3/4" across; some shade of yellow at first, fading to grey or brown in age, striate in age
Stalk sometimes yellow, often becoming deeper in color in age; often scurfy
- In my experience the cap often splits in age, but doesn't become plicate
