Observation 119555: Amanita velosa (Peck) Lloyd

When: 2012-11-27

Collection location: Bolinas Ridge, Marin Co., California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

These were growing near mixed woods of Madrone, Doug fir and live Oak.
Caps were up to 7.8 cm across.
White spores were not amyloid.
Spores were ~ 9.0-12.1 X 8.0-10.0 microns. Q(ave) = 1.23
Q ranged from 1.10 – 1.36.
Initially I thought these were somewhat abnormal A. calyptrodermas that had lost their annulus. However, they were growing undisturbed under cover of some low branches.
The spores are much fatter than the average A. calyptroderma whose average Q value is closer to 1.60.

Didn’t notice any color inside the volva

but also didn’t look super close. Funny how my mind just didn’t think about A. velosa in this particular place or time. It’s not a pure Live Oak habitat but there are scattered small Oaks. Pretty obvious now and while the color isn’t quite normal, I think the ID is right.

was the inner volva stained the cap color?

those stipes look awfully smooth for velosas.

we have seen them (velosas) before this early in the season. in fact, they seem to be appearing earlier and earlier each year.

The spores are almost a perfect match for Amanita velosa. It’s a little early, right?

Nevertheless, I’ve seen them this color in the past.
