Arrhenia epichysium is a species of agaric fungus in the family Hygrophoraceae.

The fruit body has small brown to dark gray caps measuring 1–3 cm (1⁄2–1+1⁄4 in) in diameter. The cap color changes to light gray to tan when it is dry. The gills are narrow and thin, placed together closely, and decurrently attached to the stipe,[1] which can be up to 5 cm (2 in) long. The flesh is grayish and watery.[2] The spores are smooth and ellipsoid, measuring 6–7.5 μm.[1] The spore print is white.[2]

Outside of its genus, it can resemble the slightly larger Pseudoclitocybe cyathiformis.[2]

It can be found on dead wood in North America (except for the Gulf Coast), lasting through May on the West Coast.[2]
