Amanita battarrae, also known as the Banded Amanita, is a medium-sized, grey-brown, fleshy agaric with a volval bag, but no ring or cap patches. It is distinguished from other ringless Amanita species (often referred to as grisettes) by the zoned colouring of its marginally grooved cap. It grows solitary or scattered on soil in broad-leaf woods (particularly oaks but also Ash and Hazel) and on heaths. It fruits during the summer and autumn.

Cap starts off egg-shaped, becoming convex, and then flattening while still keeping a shallow umbo. It has pronounced striations at the margin, often featuring a narrow dark band where the striations begin. The cap colour consists of a range of grey-brown shades, with the centre darkening as the fruit body matures. Occasionally, velar fragments may be present when the mushroom is young. Gills free from the stem or slightly attached to it, creamy white, close or crowded. There are often a few short gills, of variable length and irregularly distributed. Stem white or tinged with the cap colour, tapering only slightly (narrower near the cap). The base is enclosed in a sacklike, persistent, white volva with orange-brown spots. The volva is sometimes buried below ground level or in leaf litter. The stem has no ring. Spore print white.

Microscopic Features: Spores are spherical, smooth, and measure 11-13µm in size. They are inamyloid.

Note: A very similar species occurs in some parts of North America.
