ABSTRACT: Two small gymnopoid fungi from the southern Appalachian Mountains and Massachusetts, Collybiopsis complicata sp. nov. and C. prolapsis sp. nov., are identified and described. A new generic nrITS-LSU phylogeny of Collybiopsis places C. complicata and C. prolapsis in a small clade together with C. minor, and an unknown taxon from Arkansas. This clade adds to the growing circumscription of Collybiopsis (= Marasmiellus).
