it looks like photos 1 and 3 have skirt-like annulus and represent an Amanita.

Photos 2 and 4 have a collar-like annulus, and much less crowded gills. But also represnet an Amanita species.

I added “mixed collection” based upon these features: color of stalk, one individual appears cream while one appears white, the veils are different and one individual is much more robust than the other, cap color is also distinctly different.

I have been finding some small coccoras this season in santa cruz.
Happy hunting!!!

Position and size of the partial veils seem different in the two fruiting bodies.

Seems that the stem bases and the types of volvas on the stem bases are needed for ID.


There are only two mushrooms shown (top and bottom of each)

Neither were as big as local coccoras get, but they could still be so.
