Observation 83836: Amanita phalloides var. alba Costantin & L.M. Dufour
When: 2011-11-29
Herbarium specimen reported

Notes: I’ve been finding a small group of the “white phalloides” in the same area at Tomales Bay State Park foe several years. They are growing somewhat alone although A. phalloides grow almost everywhere among the oaks at this park.
I don’t know if they are really a separate species but they do seem to have their own karma. Since, MO does recognize this “form”, I might as well add to the controversy.
I did check them for KOH reaction and indeed they did not yellow.
Included is a photo comparing the look and KOH reactions on the Whites and a couple of Standard phalloides.
Spores were typical, ~ 8.0-9.0 X 7.0-8.0 microns.
