Amauroderma subsessile is a polypore fungus in the family Ganodermataceae. It was described as a new species in 2015 by mycologists Allyne Christina Gomes-Silva, Leif Ryvarden, and Tatiana Gibertoni. The specific epithet subsessile (from the Latin words sub "somewhat" and sessilis = "without a stipe") refers to "the basidiomata not completely sessile, with a short to long stipe". A. subsessile is found in the states of Rondônia and Pará in the Brazilian Amazon, as well as Costa Rica and Panama.
