A small white Amanita by the river
A small, ringed mushroom found beneath rhododendron after heavy summer rain. Its white gills, high ring and collared bulb provide several useful identification characters.
Field observation
Photographic evidence and limitations
The photographs document the cap, free white gills, ring, textured stem, collared bulb, scale and fresh longitudinal section. The stem was discarded before a delayed staining check could be completed, so the identification remains a provisional morphological comparison.

Morphological comparison
Amanita sp., cf. A. multisquamosa
The closest morphological match is the small funnel-veil amanita. Confidence is high at genus level and low to moderate at species level.
Features that fit
- Small, pallid cap with a slightly warmer disc
- Free to remote, crowded white gills with plentiful short gills
- High skirt-like ring
- White stem, finely shaggy below the ring
- Pronounced collar around the top of the bulb
- White cut flesh with a narrow central channel
Evidence still missing
- Completed, photographed spore deposit
- Spore measurements and Melzer's reaction
- Confirmed associated tree species
- Timed cut-surface staining observation
- Complete dried voucher or DNA sequence
"Cf." means "compare with." It marks the closest morphological fit without presenting the candidate as confirmed. Pale members of subsection Pantherinae and several white lepidelloid Amanita species can overlap in photographs.

From habitat to interior
How the comparison was made
The collar matters more than the color
Amanita multisquamosa is described as a small eastern North American Amanita with a pallid cap, free crowded white gills, abundant short gills, an annulate stem and a pronounced collar of universal-veil material around the top of the basal bulb. Those characters align closely with this specimen.
The photographs do not settle the species. Amanita velatipes and other pale pantherinoid taxa can share a similar collar and ring. Pale muscarioid forms and some white lepidelloid Amanita species remain alternatives. Microscopy, particularly spore measurements and an amyloid test, would be the most useful next step.

Exercise Trail #344, Davidson River
We're publishing the exact location because there is nothing sensitive to protect here, and we want people to get outside and look closely. If you visit, tread lightly and check current Forest Service notices before heading out.
At the observation date, the Exercise Trail remained publicly accessible while Davidson River Campground was closed for renovations.
