Observation 117810: Amanita pantherina (DC.) Krombh.

When: 2012-11-24

Collection location: SE 76th and Division, Portland, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

When I found this rather large fruiting, I immediately became worried. Several large buttons had been cut off above ground level, suggesting someone may have harvested them for eating. Amanita pantherina is noted for causing more poisoning cases in Oregon than any other Amanita species. I hope this is not one of them.


7 golf-ball sized Amanita buttons visible here. Just to the left and out of the shot were another 15 buttons. Associated with beech.

Interior stipe flesh turning yellowish after slicing.
Large base of button is 3-4 inches wide, but no distinct volva present.
