When: 2014-06-16

Collection location: Big Thicket, Hardin Co., Texas, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

Found in the Turkey Creek Unit of the Big Thicket National Preserve.
Caps up to 8.2 cm across, texture very thin and soft, almost like tissue paper.
Thin annulus also fragile.
Spore print white and spores amyloid.
Spores ~ 6.9-9.1 X 5.2-6.4 microns, ellipsoid.
Q(range) = 1.30-1.56. Q(ave) = 1.39.
These were strange as they looked and felt more like a Lepiota except for the amyloid spores.

This material has been received and accessioned to Rod’s herbarium.

The delicacy of the caps…

is striking and comes through clearly in your photographs.

I would be very interested to know if this is one of the rubescent taxa that we have already seen (in a more delicate fruiting body) or something new.

Very best,


Rod, yes, I think you’re right

about the reddish coloring…no red clay in that area.
They were definitely atypical of any Amanitas I was finding in the area.

Given the sandy soil in the Big Thicket, I’m assuming…

that the felsh has bruised and the reddish colors are not from red clay or some other pigmented soil

It looks like the bottom of the partial veil and the warts on the cap are both white. This eliminates one of rubescent taxa that is sometimes white and seems to consistently have yellow in those two parts of the fruiting body.

Very best,


This could be something int he rubescent group of section Validae.

I might be able to place this in one of the groups of rubescent taxa that have segregated genetically.
