Description

A brownish milkcap with very acrid white latex that rapidly turns pink in air.

Identification features

The cap is dirty- to grey-brown, velvety when dry and slightly greasy when wet. Gills are ochre; white latex quickly turns pink after damage.

Identification checklist

The key feature is the rapid pink colour change of white latex. Also check the brown velvety cap and beech habitat; FungiTrail does not recommend tasting.

How to separate similar species

Several brown milkcaps look similar; compare latex changes, tree association, and cap surface together. One feature alone is insufficient.

Habitat

Occurs mainly in beech woodland, often on calcareous soils, in summer and autumn.

Fruiting period

August, September, October
