Observation 182644: Amanita porphyria Alb. & Schwein.

When: 2014-10-11

Collection location: Mount Rainier National Park, Washington, USA [Click for map]

Who: Ron Pastorino (Ronpast)

No specimen available

These were growing on the ground in a campground @ ~ 3000 ft.
Spore print was white and spores amyloid.
Spores ~ 8.0-9.5 X 7.8-8.9 microns, globose to subglobose.
Q(range) = 1.00-1.11. Q(ave) = 1.06. n=15.
Initially these did not appear to be the typical A. porphyria that I’m used to seeing…color too dark and stature too squat. But looking at Rod’s website, they appear to be very similar to European material and spores match well.
They were left at the NAMA meeting site.

It is a bit odd that the partial veil hadn’t turned gray yet.

The spore documentation is nice, too.

Very best,
