Leucocoprinus brunneoluteus is a species of mushroom producing fungus in the family Agaricaceae.

[1][2] L. brunneoluteus was classified by the mycologists Marina Capelari and Luciana Jandelli Gimenes in 2004.

The cap surface is otherwise bright yellow with dark brown scales that become sparser away from the umbo and towards the edges.

The surface is the same yellow hue as the cap and gills and the interior is hollow.

The specimens studied by Capelari and Gimenes were collected from a state park near São Paulo, Brazil where they were found growing on the ground under Pine trees.
