same reasons as Alfredo – those gut feelings

it just looks like a Volvariella – the radial fibrils, the Gestalt, the volva -

the suggestions of Pluteus romellii (lutescens) or P. leoninus can be put to rest, as the first one has a dark brown cap surface that is a celluloderm (made up of upright short club-shaped or balloon-shaped cells, and yes you can see that with a handlens), and Pl. leoninus has a golden-brown cap surface, also not fibrillose as this one, but made up of long upright elements.

Other than the presence of volva there is no single macroscopic character that “screams” Volvariella rather than Pluteus or Volvopluteus.

The radially fibrillose cap immediately made me think of Volvariella, especially to what we call in Europe Volvariella tayloriibut that is just my impression from the photograph.

Again, to get an ID in Pluteus, Volvopluteus and Volvariella, microscopic data are always a must.

ignoring the volva, what do you see that looks more Volvariella-like than Pluteus/Volvopluteus?

I agree that it is not totally clear in the first photo but to me that looks like a brownish volva at the base of the stipe.
The general aspect of the basidiocarp is also reminiscent of Volvariella rather than Pluteus or Volvopluteus but without microscopy it is not possible to confirm it

yellow stipe?

was the stipe a shade of yellow?
it looks like this is a possibility from the photos.
this along with cap color and texture may suggest something along the lines of Pluteus lutescens or Pluteus leoninus.

distinct?

i wouldn’t go that far. upon third and fourth glances, what’s behind that leaf may very well be a volva, but it’s iffy.

the base is hidden in your first photograph and severed from the fruiting body in the following two. though unlikely, Volvariella and Volvopluteus are still possibilities until or unless we can see more detail from the base.
