I’ll keep the slime in mind. You see that’s the kind of detail that needs to be more prominently expressed. Miller says slimy but I never know HOW SLIMY is slimy. :) Course in this case it looks like I entirely overlooked slime.

If the cap was pure white at first, …

Amanita rubescens var. alba would be a possibility in this case.

Very best,

This is one of the rubescent species of Amanita…not quite slimy enough.

The surface of the cap of a Limacella is a real slime-making machine…creating special cells just to gelatinize them and turn them into goo. Then a second set of hair-like cells are created to hold the goo in place. You won’t find such things on the cap of this Amanita.

At present there are quite a few rubescent taxa in Amanita that can be separated by means of gene sequences. Some progress is being made toward finding morphological characters that separate the taxa, but it is very much a work in progress.

Very best,

Rod
