Observation 145627: Amanita sect. Vaginatae sensu Zhu L. Yang

The resemblance of this robust specimen to A. borealisorora makes me wonder just a bit. But the olive tones on the cap and the long striations point toward sinicoflava.

Hemlock and birch primarily.

A member of our local club got it in a spot where I have collected sinicoflava in the past. I have no way of knowing whether he left behind some of he volva. I have preserved the material.

I think we can sort this out.

I agree that it is very robust for sinicoflava. Also, an incompletely expanded sinicoflava should have at least the bottom half or so of the saccata volva still white and membranous around the base of the stem.

Very best,
