A common mushroom in Spring and early Summer but can be found later in the year. Although edible, the Spring Fieldcap is a little bitter and can be hard to identify to species among other Agrocybes. Agrocybe praecox is a complex of four different species that are almost identical visually and only divisible with a microscope and scientific analyses.

Scientific Name – Agrocybe praecox


Spring Fieldcap cap

6-8 cm. Dark grey/brown and greasy when young becoming dryer, off white tan to ochre until drying to near white with age. Convex opening out to almost flat usually remaining smooth and cracking in dry conditions. Can have remains of the veil on the edges.

Spring Fieldcap gills

Spring Fieldcap cortina

The young mushroom has a veil covering the gills, this soon detaches and can become the delicate and short lasting skirt.

Spring Fieldcap flesh

Off white, fibrous.

Spring Fieldcap habitat

Saprotrophic, grows on woodchip or soil in parks, gardens and paths.

Spring Fieldcap possible confusion

There are various Agrocybe and Cyclocybe species that look similar, some should be avoided so we don’t eat this one. The Poplar fieldcap (Cyclocybe cylindracea) is shown.


Bitter when raw, less so after cooking.
