Sphagnurus paluster is a species of fungus in the family Lyophyllaceae which parasitizes Sphagnum moss. It was first described by Charles Horton Peck in 1872. It is commonly called the Sphagnum Greyling due to it being found in peat bogs and to its cap turning grey as it ages and dries.
Sphagnurus paluster can be white pruinose when young and does not stain or bruise when crushed. Its flesh is thin, soft, and watery. The cap is 1 to 3 centimetres (0.39 to 1.2 in) in diameter, starting as conical or bell shape when young, expanding flat with a distinct umbo when older. It is smooth, striate, and hygrophanous; usually an olive-brown when moist, drying to a pale grey color. The white to grey gills are adnate or with a slight tooth. Subgills are often present creating a close to subdistant spacing. The stem is 2 to 10 centimetres (0.79 to 3.9 in) long and 1 to 5 mm (0.039 to 0.20 in) in diameter, equal and hollow. The coloring is usually lighter than the cap, being grey-brown or grey. The white to cream colored spores are 5.5 to 8.5 µm x 4 to 4.5 µm, elliptical, and smooth.
