Tricholomopsis sulfureoides is a species of gilled mushroom found in the United States.

Its fruit bodies have pale yellow caps with differently colored zones of paler yellow and light yellow streaks.

Young mushrooms have a thin partial veil.

The mushroom is found growing singly or in groups on rotting conifer logs.

[2] The fungus was originally described as Clitocybe sulphurea by Charles Horton Peck in 1888;[3] Rolf Singer transferred it to Tricholomopsis in 1969.
