How to tell Orange grisette from Jewelled amanita

The cap is 5 to 12 cm across, egg-shaped as it breaks out of the sac, then bell-shaped and convex, finally flat with a low, darker central bump.

It's yellow-orange to orange-brown with an apricot tinge in the centre, paler towards the edge. The surface is smooth and shiny, slightly sticky when wet, and almost never carries patches of veil. The edge is grooved like a comb.

The cap is 4 to 10 cm across, occasionally up to 12 cm. It starts convex, almost bell-shaped, then opens out flat, sometimes with a slight dip in the middle.

The colour runs from pale straw to bright egg-yolk yellow, usually darker and more ochre in the centre, and older caps fade to cream. The surface is slightly sticky in wet weather. Flat white flakes, the remains of the universal veil, sit on top, thickest in the centre. They come off easily and rain washes them away, so a cap can be completely smooth. The margin of a mature cap is grooved, with short lines like the teeth of a comb.

The gills are free, crowded, white to cream, with shorter gills of varying length in between.

The spore print is white.

The gills are free or only just touch the stem, crowded, soft and white, and may turn slightly yellowish in old specimens.

The spore print is white. The spores are smooth and broadly ellipsoid, roughly 8–11 × 6.5–8.5 µm, but that only shows under a microscope.

The stem is 10 to 15 cm tall, up to 20 cm, and 1 to 2 cm thick, tapering upwards, hollow and brittle with age, pale to deep orange with a white-and-orange zig-zag pattern of soft scales, like snakeskin. There's no ring and no bulb.

At the base is a large, thick, loose white sac (volva), often lobed and hidden in the soil.

The stem is slender, 5 to 12 cm long and 0.5 to 1.5 cm thick, white or pale yellowish, smooth or finely downy, and fragile.

The ring is thin and membranous, like a little skirt, and sits halfway down the stem or lower. It doesn't last: often all that's left is a faint mark, and old specimens may have no ring at all. So a missing ring doesn't mean it isn't an amanita.

At the bottom the stem has a small rounded bulb. The volva hugs it tightly and ends in a narrow free collar at the top, sometimes broken into one or two rings or flakes. It isn't a tall sack as in the grisettes, nor a large, abruptly cut-off bulb as in the false death cap. The bulb is often sunk in the soil, so the mushroom needs to be dug up.

The flesh is thin, white, soft and fragile, and doesn't change colour when cut.

The flesh is white, sometimes slightly yellowish in the stem, thin, and doesn't change colour when cut.

The smell is faint: some sources call it sweet and mushroomy, others indistinct.

The smell is faint, hardly noticeable. Some authors mention a slight radish note, but most field guides say there's no distinctive smell. The only lookalike you can tell by smell is the false death cap, which smells of raw potato.
