Amanita fulva: The Ultimate Mushroom Guide
About The Amanita fulva Mushroom
Amanita fulva is a basidiomycete mushroom of the genus Amanita. It is found frequently in deciduous and coniferous forests of Europe, and possibly North America.
This medium-sized agaric has a distinctive tawny cap and white gills, no ring, and usually without cap patches but with volval bag. It grows solitary or scattered on soil in mixed woodlands, favoring birch.
Amanita fulva is one of the few edible species in the genus Amanita. Though this particular species is considered edible, it must be identified with care as other members of the genus Amanita are poisonous and some are deadly. For this reason, collection for the consumption of A. fulva can be dangerous and is not recommended.
Some authors indicate Amanita fulva as is potentially toxic when raw, and is suitable for consumption only when cooked.
Other names: Tawny Grisette.

Amanita fulva Similar Species
Amanita caesarea (Caesar's Mushroom)
Is rarely if ever found except in southern Europe; its cap is a brilliant orange with a striated margin, and the stipe is orange-yellow.
Has a yellowish-orange cap with an apricot tinge at the centre. It has cream rather than white gills and a more brittle stipe that is often hollow in mature fruit bodies, and it has a sweet smell and a nutty taste.
Is similar but has a greyish cap. (For many years Amanita fulva was considered to be merely a color form of Amanita vaginata.)
Amanita fulva Taxonomy & Etymology
When Jacob Christian Schaeffer first described this species in 1774, he named it Agaricus fulvus. (Most of the gilled mushrooms were included initially in the genus Agaricus!). This was subsequently transferred to the genus Amanita by the great Swedish mycologist Elias Magnus Fries in 1815, when it was renamed Amanita fulva.
Synonyms of Amanita fulva include Agaricus fulvus Schaeff., Amanitopsis vaginata var. fulva (Schaeff.) Sacc., Amanitopsis fulva (Schaeff.) Fayod, and Amanita ochraceomaculata Neville & Poumarat.
The specific epithnet fulva means reddish brown (tawny!).
