That’s why I guessed curtipes as the species name.

R.

The scale of needles and leaves in the photo points to the mushroom not being “VERY LARGE”.

I’m sorry but I don’t have sufficient evidence that could point either way. But thanks for your comments just the same.

I think I see a volva peaking up through the substrate; and, therefore, I might assume that the stipe is rather short in proportion to the width of the cap. Can you tell us if the volva was in the form of a sack? I will guess that it was saccate. The striate margin of the cap and the apparently ringless stem then suggest Amanita sect. Amidella or Amanita sect. Vaginatae. The very short stem (if normal for the species you have photographed) could suggest the former section: Amanita curtipes if the specimen is NOT very large and Amanita ponderosa if the specimen IS VERY LARGE. Both occur in Portugal.

Do you have evidence that confirms or refutes any of the above guesses?

Very best,

Rod
