North American collections previously referred to the genus Gongylia Körb. are re-assessed. The collection previously referred to G. muscorum Zschacke is shown to be an undescribed species of Protothelenella Räsänen, for which the name P. pluriseptata Fryday is proposed, and the collection previously referred to G. nadvornikii Servit is shown to be referable to Segestria mammillosa Th. Fr., which is reported for the first time from Alaska and the North American Arctic. As a result, Gongylia muscorum and Sagediopsis barbara (Th. Fr.) R. Sant. & Triebel, which is the correct name for G. nadvornikii, should be removed from the North American flora.
