Agaricus silvicola



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


Arvenses     Section
Cap up to 7" across
Flesh stains or ages yellow, and stays yellow (on its own, or with KOH)
Partial veil usually has two distinct layers.
Mature fruiting body usually quite tall (stem 5-10" long), and often quite wide as well
Odor sweet, usually almondy, sometimes of anise, but different people will sometimes perceive it differently
The gills are greyish at first, not pink


Gracile Arvenses     SubSection
Cap up to 6" across, sometimes slightly silky
Stalk long and gracile in proportion to the cap
Yellowing reaction and scent usually discreet
Usually in troops in the woods

Comments

A tall, gracile mushroom, all white; the first time I saw it, I thought it was a deadly destroying angel, and I was scared to death, because there were half a dozen of them
The yellowing reaction, in my experience, is primarily seen in the nicks and dents the mushroom gets coming up through the soil.
It often grows in troops, sometimes quite thickly (bonanza time for dinner!)
