Amanita rubrovolvata
Amanita rubrovolvata, commonly known as the red volva amanita, is a species of fungus in the family Amanitaceae. The fungus produces small to medium-sized mushrooms, with reddish-orange caps up to 6.5 millimetres (1⁄4 inch) wide. The stems are up to 10 cm (4 in) tall, cream-coloured above the ring and cream to yellowish below it. The stem ends in a roughly spherical bulb at the base, which is covered with bright orange patches.

First described scientifically by the Japanese mycologist Sanshi Imai in 1939, the fungus is widely distributed in eastern Asia. Neither its edibility nor toxicity have been established, but it is suspected to be associated with neurological anomalies. Several molecular studies have confirmed the mushroom's classification in the subgenus Amanita of the genus Amanita, along with closely related species such as A. muscaria.
