Observation 11718: Amanita Pers.

When: 2008-09-30

Collection location: Southeast Portland, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

Observed at Portland Adventist Hospital in SE Portland. This Amanita species has a cap less than 1.5 inches across, is about 4 inches tall including the hypogeous volva, has a very thick volva as well as annulus. A portion of the annual is firmly attached to the cap edge, covering most of the gills. There is a series of bands on the stipe which is unlike any other Amanita I’ve seen before. There were 4 specimens total at the site, in th same square foot. The oldest had a honey-brown cap, but still had the concentric cracking in the cap. Have ruled out A. volvata, but still don’t know what it actually is.

..I think that this is an amanita that has cracks and rings due to growing conditions. i have seen this in CA, too. might just remain a mystery as to species, tho…

Can’t see volval patches on cap

Maybe this isn’t an Amanita? Got to go back, take more pictures, get a spore print, and collect all of the specimens. Quite a variation in size, color, and age. All had that distinctive rings on the stipe, though. Need to check nearby trees for possible hosts, too. This is the only Amanita I’ve found in that area.

probably an unnameable environmental oddity.
