Dentocorticium sulphurellum is a species of crust fungus in the family Polyporaceae.
It is characterized by its toothed surface, its sulphur-yellow colour, and microscopically by the presence of dendrohyphidia in the hymenium.
Charles Horton Peck originally described it in 1879 as Hydnum sulphurellum;[5] it was transferred to Dentocorticium in 1974.
[6] It is found in North America and Japan.
