Amanita crocea: The Ultimate Mushroom Guide
About The Amanita crocea Mushroom
This lovely mushroom is distinguished by a thick, white volva, faint zig-zag white-and-orange stem markings, and an absence of veil remnants on the cap. The cap is 3 to 13 cm in diameter; yellow-orange with an apricot tinge at the center. The gills are cream, crowded, free or sometimes adnexed.
The fungi can occur infrequently between July and October in mycorrhizal with hardwood trees, particularly birch and beech in clearings. Its odor is sweet-smelling and it has a mildly nutty sweet taste. It has also been reported from Iran.
While edible, guides advise not to eat it as many Amanitas are very poisonous.
Other names: Saffron Ringless Amanita.

Amanita crocea Taxonomy & Etymology
Described in 1898 by Lucien Quélet, who named it Amanita vaginata var. crocea, this lovely mushroom was given its currently-accepted scientific name in 1951 by the famous German-born mycologist Rolf Singer.
Synonyms of Amanita crocea include Amanita vaginata var. crocea Quél., and Amanitopsis crocea (Quél.) E.-J. Gilbert.
The specific epithet refers to the saffron coloring of this mushroom. Saffron is an orange-yellow spice derived from the flowers of the Saffron Crocus, Crocus sativa. The generic name Crocus comes directly from the Latin word crocus - hence crocea.
