Observation 93442: Amanita ameripanthera group
When: 2012-04-27
No herbarium specimen

Notes: This wikipedia article needs to be tweaked I think:
http://en.wikipedia.org/...

What are we calling this species in the PNW?

Additionals: Gills are closely spaced and are very white. Stems solid (no hollow center). Annulus is halfway down on stems – sometimes lower.

Microscopy was difficult to see and I assume the same for others based on the lack of elaboration within the Wikipedia article. I couldn’t capture any cystidia actually attached to the sections I made.

Pileipellis can literally be removed with ease by peeling it back. Spore print is white.

Aroma is very mild and if anything smells like a mushroom, no sarcasm injected.

I am totally guessing but I believe this species produces extra oil deposits which attributes to both the poor, layered visibility but also many tiny cells that have an oily/inside-a-spore kind of appearance. Question: What are these tiny, oil-like drops with what appears to be one or up to six extensions with additional heads?
