Observation 161335: Amanita sect. Vaginatae sensu Zhu L. Yang
When: 2014-03-13

Notes: Single fruit-body growing in mixed woods, mostly firs and tanoak.
Cap 4.5 cm wide and total height of 12.2 cm.
Cap fairly viscid with thin striations up to 15 mm long.
Spore print thin but appeared sl colored(orangy) and not amyloid.
Gills also appeared to be v. sl orangy.
Spores ~ 10.0-12.2 X 9.0-11.9 microns. Q(range) = 1.0-1.11 Q(ave) = 1.05.
I guess it could be a whitish form of one of our Grisettes.

Rod, I was a little impatient

so I just cut a section of the cap as pictured.
Over night I did get a fair number of spores, just not as thick as one might like.
I think it was reasonably mature but not well-aged like us.
I’ll send it to you.
It’s only the second “white” Grisette I’ve ever found.

Did you let it expand a little before it dropped spores?

My guess is that you did. Did you keep the base moist during the cap expansion?

We could try DNA sequencing…

Very best,

Rod
