Around pine trees, annulus fell off, had a brownish red/orange color on the stipe that stains the fingers when held.

The striate cap margin suggests this species might be in section Amanita.

This is consistent with rusty colored pulverulence on the stem. There is a somewhat similar species in eastern Asia—Amanita rufoferruginea. Your specimen may be larger than the size of that species reported from Japan, China, etc.

Very best,


The stem seem to have been floccose before handling.

The floccose material remains on the upper and lower stem. It would be good to collect further evidence that the species is in Amanita. It is certainly unusual for the genus. Do the gills have typical Amanita edge tissue (at least in young material)? Does the stem have typical Amanita stipe cells? Is the gill trama bilateral and divergent? The stem tissue is critical and relatively easy to see if the tissue is spread with dissecting needles and stained with something like Congo Red.

Very best,
