Amanita fulva, commonly called the tawny grisette or the orange-brown ringless amanita, is a basidiomycete mushroom of the genus Amanita. It is found frequently in deciduous and coniferous forests of Europe and possibly North America.
Taxonomy
Amanita fulva was first described by Jacob Christian Schäffer in 1774. It is up to in diameter, convex to plane or umbonate, and orange-brown to reddish-tan. It is viscid when moist.
The spores are white, 9 × 12 μm or (9.0-) 10.0–12.5 (-19.3) x (8.2-) 9.3–12.0 (-15.5) μm in size, globose; nonamyloid.
Similar species
A. vaginata is very similar, but is not as fulvous in color. It grows in acidic soils and fruits from summer to late autumn (May to November in the United Kingdom). It is a common to scarce fungus and is very common in Britain.
Amanita fulva is considered to be widely distributed in North America in deciduous and coniferous forests, although collections could possibly be of a different, yet undescribed species. Additionally, the name A. fulva has previously been misapplied to other North American taxa, such as A. amerifulva and others.
Edibility
Although this Amanita fulva is considered edible, it must be identified with care as some other members of the genus Amanita are poisonous and a few can be deadly. For this reason, consuming A. fulva can be dangerous and is not recommended. It is potentially toxic when raw and suitable for consumption only after cooking.
