Lookalikes to rule out

A small brown lawn and mulch mushroom with rusty-brown spores and amatoxins.

Other Stropharia

caution

Related species are smaller or have a different cap color and ring.

Identification

Young caps are wine-red to burgundy, fading to tan. Gills start grayish lilac and darken to purple-black. The thick white stem carries a ring whose upper surface is split into ridges like a cogwheel, and white cords spread at the base. Spores are dark purple-brown.

Uses and ecology

Wine caps are a popular garden mushroom, grown in wood-chip beds, and they help build soil. Wild patches appear in landscaping mulch. Pick young caps.

Memorable fact

Gardeners grow wine caps between vegetable rows, where the mycelium breaks down wood chips into compost.
