Description

A tiny cup-like fungus that reveals several pale lentil-shaped peridioles after opening, resembling eggs in a nest.

Identification features

Fruitbodies are about 5–10 mm tall, yellowish-brown and finely hairy outside. A membrane closes the young cup; later smooth pale peridioles are exposed.

Identification checklist

Check the small pale cup with smooth interior and several pale peridioles; the inside is not ribbed as in Cyathus striatus.

How to separate similar species

Cyathus olla is usually larger and greyer; Cyathus striatus has a distinctly longitudinally ribbed interior.

Habitat

Grows on decaying plant debris, small wood fragments, mulch and straw from spring to autumn.

Fruiting period

May, June, July, August, September, October
