Type species: Acanthotubeufia filiforme (Promp. & A.N. Mill.) Y.Z. Lu & K.D. Hyde, Fungal Diversity 92: 146 (2018).
≡ Acanthostigma filiforme Promp. & A.N. Mill., Mycologia 102(3): 575 (2010).
Notes: Acanthotubeufia was introduced based on morphological and phylogenetic analyses. Its morphology is similar to Neoacanthostigma and Acanthostigma with one-celled or rarely one-septate setae covering the globose to subglobose ascomata, but differs by its longer, narrower and symmetrical filiform ascospores (Promputtha and Miller 2010, as Acanthostigma filiforme; Lu et al. 2018b).
