About this fungus

Grey-veiled Amanita is a fungus in the Amanitaceae family. Its habitat and field characteristics are summarised below.

A slender woodland Amanita with a smooth grey-brown to purplish-brown cap, usually carrying a few grey veil patches. It has free white gills, a thin upper ring and a broad basal bulb edged by a close-fitting rim.

What to check

Expose and inspect the entire stem base. The bulb is broad and normally has a distinct rim or margin rather than a loose sack. Check the free white gills, white spore print, thin greyish ring and grey veil patches together. The ring may collapse and cap patches can wash away, so neither is reliable alone.

Variation

The cap ranges from pale grey-brown to dark purplish-brown and can look shinier when moist. Veil remnants vary from several grey patches to almost none after rain. The ring is often fragile, while the bulb may remain hidden in soil unless the whole base is examined.

Lookalikes

False Death-cap, Amanita citrina, is usually paler and often has a raw-potato smell, but it shares a margined bulb. Panthercap, Amanita pantherina, often has whiter cap patches and a differently ridged bulb, yet weathered specimens can overlap. Other grey-brown Amanita species may require microscopy or specialist regional knowledge.

Habitat and range

Ectomycorrhizal on acidic woodland soil with conifers and broad-leaved trees, including spruce, pine, birch and beech. It is best documented across Europe and northern temperate regions and fruits mainly from summer into autumn.

Food safety

Inedible.

Weather response

A repeatable weather association was found in the records, alongside the usual seasonal pattern.

Higher or lower ground?

Records tended to come from higher ground relative to other fungal records in the study.

These are patterns in recorded observations, not rules, forecasts or identification evidence. Local conditions and recording patterns can affect the findings.
