It looks as though there is a margin on a basal bulb in the first image.

This makes me think of the bulbosa-porphyria-lavendula group in the Validae.

A couple of years ago, I saw Schweinitz’s original watercolor of A. porphyria. It was entirely gray (although it was “stylized”). In North America and northern Europe, the material of A. porphyria (despite very minimal variation in nrITS and nrLSU genes) has considerable variation in cap color, including caps with radial “hairs” (fine streaks) of color in the cap. I’m wondering whether this might be another color variant of porphyria.

Very best,

Rod

Amanita vaginata…

should have no ring on the stipe. Also, the margin of the cap seen here appears to lack radial srtiations (grooves). The margin seen here appears to possibly be “innately streaked” which is different from striate. Innate streaks are not ridges/depressions.
