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.
Fruiting body containing fibers (usually in the stalk)
Spore print chocolate brown
Annulus almost always present, usually membranous
The gills are usually pink or silvery-grey at first, but are colored chocolate brown at maturity from the developing spores
The cap and stalk are usually some sort of white or greyish brown, but may have fibrils or scales that are darker (like the portobello)
Growing on the ground, wood chips, or other organic debris
Cap up to 2" across
Flesh stains or ages yellow, and stays yellow (on its own, and with KOH)
Partial veil has only one layer; typically it forms a very fragile ring, often disappearing in age
Odor sweet, sometimes faint
Fibrillose Minores SubSection
Stalk staining yellow, orange or rusty orange below the ring
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 1 3/4" across
Fibrils pinkish, purplish, "amethyst-gray" or reddish brown; sometimes only on the disk
