Type speciesHalobyssothecium obiones (P. Crouan & H. Crouan) Dayar., E.B.G. Jones & K.D. Hyde, Mycol. Progr. 17 (10): 1165 (2018).

Pleospora obiones P. Crouan & H. Crouan, Florule Finistère (Paris): 22 (1867).

Notes – Dayarathne et al. (2018) introduced Halobyssothecium to accommodate Byssothecium obiones (= H. obiones) from salt marsh halophytes. It differs in morphology from the other members in Lentitheciaceae in having versicolored ascospores with brown central cells and hyaline end cells, which resemble Byssothecium.
