Type species – Diademosa californiana (M.E. Barr) Shoemaker & C.E. Babc., Can. J. Bot. 70(8): 1641 (1992).

≡ Graphyllium californianum M.E. Barr, Mem. N. Y. bot. Gdn 62: 40 (1990).

Notes – Diademosa is easily identified based on its ascomatal opening through a circular lid and ascospores often circular in end view. Diademosa differs from Comoclathris in having cylindrical ascospores, often round in section, but constricting to one end of the spore, compared to the flattened ascospores of Comoclathris. Diademosa was placed in Pleosporaceae by Ariyawansa et al. (2014a) based on morphological similarities to other genera in the family. The asexual morph is unknown (morphology see Ariyawansa et al. 2014a).
