Fibrillose Minores     SubSection



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.



TricholomaAgaricales     Order
Fruiting body containing fibers (usually in the stalk)


Agaricus campestrisAgaricus     Genus
Gills free
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


Minores     Section
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

Diagnosis

Comments

The fibrils sometimes clump together into tufts that some authors call scales
It's unclear to me whether the two species in this section are truly distinct

Narrow down your identification:


Agaricus diminutivus
Cap up to 1 3/4" across
Fibrils pinkish, purplish, "amethyst-gray" or reddish brown; sometimes only on the disk
Odor faint, like anise, or absent
Growing in woods

Agaricus micromegethus
Cap up to 2 3/4" across, white to buff; sometimes bruising like the stalk
Fibrils yellowish brown or pinkish at first, but soon aging greyish brown
Odor strong, anise-like
Growing in lawns
