Striation is not a reliable feature.

It does look like excelsa indeed but the grey scales are missing. Never an excelsa (spissa) without grey scales.

My heart is more with spissa now, after careful reading of field guides. Pantherina should be striped on cap and more bulbous.

Cap size

And maybe this important detail: cap size +- 5cm.

Scales / color

Color is fairly accurate on the photos.
In reality, scales are a bit whiter and the cap is a bit more brown.

I am not content with pantherina too,

but A. excelsa ALWAYS has grey cap scales. Maybe the light in the photos is a bit unnatural. I cannot say with certainty that they are white but I believe so. Amanita echinocephala/solitaria has erect scales. Maybe A. gemmata if the cap color is not that brown?
I cannot think of any other species besides those mentioned.

The rings on the upper bulb…

and the pointed base of the bulb are what made me feel that pantherina was problematic.

Is it well known that the volva of excelsa is gray even in very immature material? I simply lack the experience of the fresh material.

and an oddly shaped stembase (for pantherina)..
Is Amanita solitaria out of the question?

Probably not excelsa

Stipe should be striate above ring for A. excelsa and grey patches on cap more extended and more grey.

Perhaps, one might consider excelsa.
