Notes: The typification of the genus Anthostomella is long confused as Saccardo never designated any type material for Anthostomella. Eriksson (1966) designated Anthostomella limitata Sacc. as the lectotype material, the only one with the original three species with non-appendiculate ascospores. Francis (1975) disagreed to this typification because A. limitata has no true clypeus, which is the Taxonomic rearrangement of Anthostomella 521 key taxonomic feature of the genus and ascospores have diagonal or spiral germ slit that is not common to many Anthostomella species. Hence Francis (1975) selected Anthostomella tomicoides Sacc. as the type of the genus but she was unable to locate the material and selected Anthostomella italica subsp. affinis Sacc. as the neotype. Lu and Hyde (2000) located the original material of A. tomicoides and lectotypified it. Since no living culture of A. tomicoides is available for now, we used A. formosa, which is morphologically similar to the type for stabilization of Anthostomella sensu stricto. Anthostomella formosa is similar to A. tomicoides by having darkened, coriaceous ascomata immersed beneath the clypeus, with central, periphysate ostiolar canal and appendage bearing ascospores with thin mucilaginous sheaths and straight germ slits (Lu and Hyde 2000).
