image 16382 & 16386

Images 16382 and 16286, which are of buttons, appear to have a membranous white layer resting above the pileus. It would give the impression that A. roseitincta has a universal veil (UV) conformed not only by the powdery layer and wart layer but also an outer membranous layer. A membranous UV is not reported in any descriptions by Murrill or Jenkins & Vinopal.

It is possible that what these images show is a consequence of various factors already observed before in A. roseitincta:

1) a membranous partial veil (PV) found, at times, resting at the bottom of the stipe just above the bulb
or
2) tearing irregularly while remaining attached (in parts) to the pileus margin, and later may completely fall off
and
3) solitary or gregarious habit

Considering these last two characteristics I believe that what the images (18382, 16386) are showing is a PV of another fruiting body which has fallen off and landed on the button.

Although nothing has been mentioned here in regards to the membrane in these images, I would like to add my interpretation of what I am observing.

Sandy soil

The earth around these is full of sand its strange, youll be walking along and notice huge patches of sand here and there. I find many mushroom species that love sandy soil in the area.

Deb, you might have needed a lower altitude…

The big collections of this I’ve seen came from sandy pine-oak woods in the coastal plain(s) or pine forest in the Piedmont or inner coastal plain. Anybody have other experience?

yes it was orangish/pink the color in the pictures doesnt do them justice. Ive never seen an Amanita with colors like this, so beautiful. The veil was pinkish/peach colored.

true colors…

Was the cap’s powdery (lower) layer of volva really so olivaceous? When the pigment is as intense as it appears in these pictures it is usually in the orange to pinkish range.
