Type species: Tubeufia javanica Penz. & Sacc.
Notes: Tubeufia is the type genus of Tubeufiaceae, established by Penzig and Saccardo (1897) based on the type species T. javanica. Boonmee et al. (2014) designated the epitype of T. javanica with phylogenetic analyses. Lu et al. (2018) reappraised the taxonomy of Tubeufia and introduced 18 species and six combinations in this genus based on phylogeny and morphology.
