Description

A grey to nearly black saddle fungus with an irregular saddle-shaped head and a characteristically deeply fluted hollow stem.

Identification features

Head about 3–5 cm wide and 4–7 cm high, irregularly lobed and wrinkled, light grey to almost black. Stem 3–8 cm tall, whitish-grey to grey-brown, hollow and strongly deeply fluted or ribbed.

Identification checklist

Key features are the grey to black lobed head and the strongly longitudinally fluted, hollow, paler stem.

How to separate similar species

Similar Helvella species may have dark lobes but usually lack such a strongly pitted, fluted stem. Atypical specimens require caution.

Habitat

Grows in deciduous and coniferous woodland, often on sandy ground beside paths and wood-storage areas, in summer and autumn.

Fruiting period

July, August, September, October
