False Deathcap

Amanita citrina Pers.

2 Observations
4 weeks ago Last Observed

The False Deathcap (Amanita citrina) is one of the commonest Amanitas in British woods. Its pale yellow to whitish cap is scattered with flat patches of veil, and the free gills are white to pale yellow. The pale stem carries a hanging ring near the top and ends in a large, rounded bulb with a distinct rim. A strong smell of raw potato is the best clue.

It grows with both conifers and broadleaf trees, especially beech, from July into November, and is very common and widespread. An all-white form, var. alba, also occurs.

Despite its name, it is no safe stand-in. The deadly Deathcap (Amanita phalloides) has a greenish-olive cap and a loose, bag-like volva rather than a rimmed bulb, and the white form can be mistaken for the Destroying Angel (Amanita virosa). The False Deathcap is not one of the deadly species, but it must never be eaten.
