Notes: Amanita cf. vaginata, a new one for me.
First photo is of the mature mushroom, taken on the 17th.
Next three photos are of its picturesque little button when I first found it on the fifteenth.
Next five are various shots taken two days later after the cap had opened out.
This one seems to have two veil layers that break up over the cap surface, a volva, and no ring.
