About this fungus

Powdery Brittlegill is a fungus in the Russulaceae family. Its habitat and field characteristics are summarised below.

A grey to blue-grey or grey-green brittlegill with a dry frosted bloom on the cap when fresh.

What to check

Look for the fine powdery cap coating, brittle pale gills and flesh, a white stem that may develop small rusty marks, and a cream spore print. The bloom can disappear in rain or through handling. There is no ring or volva.

Variation

Caps vary from grey and blue-grey to grey-green, brownish or faintly purple. Old or rain-washed caps may lose the feature that gives the species its common name.

Lookalikes

Russula cyanoxantha has unusually flexible, greasy-feeling gills rather than brittle ones. Russula azurea is more strongly associated with spruce and has a whiter print. Grey-green Russulas remain difficult and microscopy may be needed.

Habitat and range

Mycorrhizal with broadleaf and conifer trees. European accounts often emphasize oak, beech and pine, but host patterns and similar species vary by region.

Food safety

Edible.

Higher or lower ground?

Records tended to come from lower 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.
