Description

Amanita calyptroderma Amanita lanei 1 Santa Cruz Nov 07 Smjpgm1346136583

This mushroom is recognized by its large, orange-brown cap partially covered by a thick patch of universal veil, its white gills and spores, its cream-colored stalk adorned with a partial veil, a partially hollow stem (filled with a stringy white pith), and by the presence of a large, sacklike volva at the base of the stalk.

The spores of this species do not change color when placed in a solution of Melzer's reagent, and thus are termed inamyloid. This characteristic in combination with the annulus and absence of a bulb at the base of the stalk place this mushroom in the Section Caesareae.
