'''''Amanita calyptroderma''''' also known as '''coccora''' or '''coccoli''', is a white-spored [[mushroom]] that fruits  naturally in the coastal forests of the western [[United States]] during the fall and winter.

==Description==
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 (mycology)|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''.

==Distribution and habitat==
This mushroom forms [[mycorrhizae]] with [[madrone]] (''Arbutus menziesii)'' in the southern part of its range (Central California northwards to Washington).  However, in the northern part of its range (Washington to southern Canada), its preferred host is [[Douglas fir]] ''(Pseudotsuga menziesii'').

==Edibility==
Experienced mushroom hunters regard this mushroom as a good edible species, but caution must be exercised when collecting ''A. calyptroderma'' for the table, since it can be confused with other species in the genus ''Amanita''. This genus contains some of the deadliest mushrooms in the world, most notably ''[[Death cap|A. phalloides]]'' and ''[[Amanita ocreata|A. ocreata]]''.

==Related Species==
''[[Amanita vernicoccora]]'' is a closely related taxon which was previously referred to as the "spring form" of ''Amamita calyptroderma''.
