And I have since thought a lot about this and agree that its not likely they are A. calyptroderma.

tastes vary…

many amanita sp. smell fishy, including velosa, calyptroderma and even sometimes muscaria!

both velosa and calyptroderma have hollow stipes stuffed with pith or gel.

the cap color depicted here is classic velosa; spring coccora/calyptroderma does NOT show warm, pink or orange tones: it is white or a cool, pale yellow.

even an exannulate velosa can show a ring of material around the stipe where the cap broke off during development; some of us call this a pseudo-skirt
(see the BAMS velosa page here for more examples: http://bayareamushrooms.org/... )

there are always a few genetic anomalies (Arora’s single velosa that showed a membranous annulus), but they certainly are NOT the norm. The preponderance of evidence shown here sez what you have is a velosa.

You all have more experience then me. Though I still find the taste difference a bit questionable. For fresh fruit bodies to take on qualities completely unlike the norm and so reminiscent to another similar looking species certainly made me reconsider my initial id.

As for the veil, Arora claims (Mushrooms Demystified, in the velosa description) to have found A. velosa with a full membranous partial-veil that covered the gills and broke into an annulus, so I wouldn’t think it’d be that unlikely for A. calyptroderma to be lacking an annulus.

Those others are definitely the “spring form” of A. calyptroderma – notice the different color, robust stature, and the fact that there is an obvious partial veil at the top of the stipe, which is mostly smooth.

A. velosa has a shaggy stipe without a strong partial veil (usually entirely absent), like what you have depicted in this observation.

This is pretty classic A. velosa.

Also note the hollow/stuffed stipe here:


A. velosa usually lacks this…

In my experience, every Amanita has its own unique taste, ones I have tasted being A. velosa, A. calyptroderma, A. novinupta, A. constricta, and A. ocreata (Which I spat out after a few seconds of course). The taste for these specimens was consistently fishy like A. calyptroderma (The only one of the bunch that tastes like this) and not like the rich nutty flavor of A. velosa. As for color and season, here is another A. calyptroderma from a little over an month ago and nearby to this spot with the similar colors – http://mushroomobserver.org/63733?q=3zys
And another more recent one – http://mushroomobserver.org/63994?q=3zys
Though both species grow near that spot and both have been seen under shade and out in the open.

is not diagnostic. All Amanita get fishy.
Habitat, season, color, stature, all point to A. velosa.

Was not nutty, I have tasted both species before and they definitely taste different. The volva is also thicker and slightly different then the A. velosa volva in observation 64890.
