Type species: Trichodelitschia bisporula (P. Crouan & H. Crouan) Munk, Dansk bot. Ark. 15(no. 2): 109 (1953).
≡ Hormospora bisporula P. Crouan & H. Crouan, Florule Finistère (Paris): 21 (1867).
Notes: Trichodelitschia was erected by Munk (1953) to accommodate Trichodelitschia bisporula, which was previously known as Hormospora bisporula. Initially, Trichodelitschia was placed in Sporormiaceae by Munk (1957), but later Lundqvist (1964) suggested it be transferred to Phaeotrichaceae. Trichodelitschia species are characterized by having dark thick-walled spiny appendages, dark two-celled ascospores with hyaline to subhyaline tenninal apophyses and circular germ pores at the spore apices (Ebersohn and Eicker 1992). Five Trichodelitschia species are accepted in Species Fungorum (2020), i.e. T. adelphica, T. bisporula, T. lundqvistii, T. microspora, and T. munkii.
