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]
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.
