Agrocybe arvalis, commonly known as the digitate fieldcap[1] or tuberous fieldcap, is a species of mushroom. It grows in garden beds and on woodchips.[2]

Description

Agrocybe arvalis has a brown, hygrophanous cap and brown spore print.[3] It does not have an annulus. The cap is 1-3 centimeters in diameter. The gills start out yellowish buff in color, and darken in age. The stipe is 5-10 centimeters long and 2-4 millimeters wide.[2]

This species fruits from a sclerotium.[2]

Spores are elliptical and smooth, ranging from 9–10.5 × 5.2–6 µm.[2] Pleurocystidia can have 3–5 apical, finger-like projections.
