Observation 187862: Amanita muscaria subsp. flavivolvata Singer

When: 2014-11-09

Collection location: Rooster Rock State Park, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

One of the more colorful Amanitas I have found. Under Lodgepole pine. Several specimens in various degrees of maturity, many over-mature. Similar to Amanita muscaria.


In situ.
White the edges of the cap have been notched (due to age?) the cap is not striate. Volval patches extend to edges of the cap. Cap color varies from an orange-yellow color to deep red. Stipe is white to off-white in this stage.
This nice button has had most of the volval patches washed off, but remains un-opened. It is 5 inches tall (12.7 cm). Volva is not collar-like and not scaly. But I’d say more scaley than otherwise. The stipe itself is clean, white, and does not (or will not) have scale patches on it.
Detail of volva, with volval rings sluffing off.
Unopened cap. Just these 2 volval patches remain from heavy rains yesterday PM and this AM.
