Amanita parcivolvata



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)



Amanita caesareaAmanita     Genus
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)


Amanita muscaria var. muscariaAmanita     Section
All yellow-capped Amanitas can go here
All Amanitas with concentric, toothed rings around the base of stalk definitely go here
No volva; basal bulb sometimes small, often rimmed in one way or another
Universal veil generally leaves remains on cap as small scattered patches

Amanita     SubSection
Amanita muscaria var. formosa
Base of stalk has concentric, toothed rings
Annulus usually present; usually (in my experience) jagged at the edges
Links from Look-alikes
Vaginatae     Section
Amanita V3
Cap margin distinctly striate in maturity
Either (most commonly) annulus absent and colors brown or grey, or
(rarely) annulus present and colors bright: red, orange or yellow
Volva sack-like in some species, in others clamped tightly to the stem, leaving traces in bands of color on the stalk

Amanita parcivolvata     (Peck) E. J. Gilbert

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

Comments

This is a south-eastern species, very common along the gulf coast and just north of there. It occurs occasionally as far North as New Jersey, so there's no reason not to find it now and again in the mid-West
