Marasmius albogriseus is distinguished by a translucent-striate, whitish-beige to greyish cap, distant, deeply adnexed, greyish-white gills, and by a stipe that is pallid cream colored at the top and yellowish beige to ocher-yellow below. Marasmius oreades is similar but it has a warmer beige-ocher cap without grayish tones and grows in grassy lawns. Marasmius calhouniae has thinner flesh, more decurrent gills, and a fragile stipe.
