Cream coloured when fresh changes to light Grey as it ages.

When young they are a beige colour, but as they age this turns to grey, then black. Stipes are white, downy at base. It is quite common in the autumn, and is not poisonous, but not worth eating.

Stem 15-40 x 1-3mm, hollow, fragile; white with a buff tinge near the base, which is covered in white down; smooth to minutely hairy. Flesh fragile. Spores ellipsoid to almond-shaped, smooth.
