Who: Thea Chesney (thea)

Specimen available

I’ve never seen a Volvariella with veil remnants on the cap or with such an indistinct-to-nonexistent volva, so I am confused by this mushroom! I think Pluteus is also a possibility, but as far as I know, they have no universal veil at all.
This was growing in a pile of this year’s wood chips, solitary and beginning to dry up. At first glance, Amanita came to mind because of the veil patch and the nearby oak, but the gills and spores are dark pinkish and the volva, if there is one, is so insignificant (see close-ups of stipe base). It was also on top of a pile of woodchips several inches deep, which made me think Pluteus.
The stipe really looks like that of a Pluteus, with tan fibrils. The odor is mild or slightly fruity, but not raphanoid. The cap is shiny, so was probably viscid when fresh.
I’m drying it out for further inspection…
