Amanita onusta



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 cokeriLepidella     Section
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

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.

Comments

Actually, this is a fairly wretched picture of Amanita onusta: in the real thing, the partial veil is very fragile and soon disappears - - there is never an armilla as shown in the picture; and of course there is a rooting base. But it does capture the cap features very nicely, especially the pointed dark-grey universal veil fragments
