8% (3)
Recognized by sight: cap color, thin volval patch, dissolving annulus, waxy stipe.
59% (2)
Recognized by sight: Probably one of the undescribed local Amidella.
Non-striate margin of young specimen rules out A. calyptratoides, and further evidence is provided by the very robust stipe and thick volva, the former is adorned with cracked/scaly zones. The fruiting in April is another good clue.

peering back in time …

I agree that this is probably not calyptratoides, but not for the reasons stated by Christian. Calyptratoides can indeed have non-striate caps; I have collected and documented this. They can also be found in April, so not sure what C was getting at as to timing.

However, looking a bit harder, the stipe doesn’t really look like a calyptratoides stipe, which I seen quite a few times in the past several years. This was a particularly good year for them in CA.

This volva is weird … so thick, and possibly multi-layered. There is certainly an annulus, which leaves out the grisettes. I would love to see much younger material, where an appendiculate cap margin would help to nail the possibility of this being an unnamed CA amidella.

But for now, Amanita sp. is probably our best name.

I think that greenish internal color is derived somehow … maybe the inner context is starting to liquify? More fbs over time would tell that tale.

The lime green interior was the color when I sliced it open. NO INFECTION or parasite. Also no color change, not an oxidation. The center was filled with a gel.

Remember this?

Did this specimen appear to be infected or is that an inherent color or staining reaction?
