 The Argentinian species "S. nothofagi", known only from Tierra del Fuego, has been proposed for inclusion in the IUCN Red List of Threatened Species due to its highly restricted distribution and rare occurrence.The genus was circumscribed by Czech mycologists František Kotlába and Zdeněk Pouzar in 1958 with "Skeletocutis amorpha" (originally described as "Polyporus amorphus" by Elias Magnus Fries in 1815) as the type and only species.The generic name "Skeletocutis" is derived from the Ancient Greek word ("skeleto", "dried up") and the Latin word "cutis" ("skin").
