Amanita longipes

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)

Fruiting body having a combination of some of the following characteristics:
Stalk growing out of a cup of cottony tissue called a volva (all white-spored mushrooms with a volva go here)
Cap with scattered patches or flakes of the same sort of tissue as the volva (see second picture), easily peeled off
Annulus (skirt-like ring on stalk)

Annulus present
Volva absent; base of stalk swollen and rooting
Universal veil material often very powdery, or leaving very pointy remnants on the cap
Cap usually white or grey

Amanita longipes     Bas

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.

Diagnosis

• Entire fruiting body white
  
• Universal veil material very powdery, covering entire stem with tiny flakes that come off on your hands whenever you handle the mushroom
  
• Basal bulb only a slight, smooth swelling

Microscropic Characters

• Spores 8-18 (!) x 4-7 µm
