Humidicutis marginata is a gilled fungus of the waxcap family.

The species was first described as Hygrophorus marginatus by Charles Horton Peck in 1876.

[1] William Alphonso Murrill called it Hygrocybe marginata in 1916.

[2] It was transferred to the new genus Humidicutis by Rolf Singer in 1958,[3] who had previously placed it in Tricholoma.

[4] It is considered edible with a pleasant taste, but one guide says it is "not worthwhile".
