We know nothing of this species. Our specc. (2361) are Doth- 

 idea concaviuscida, E. <fe E.. which agrees with this only in external 

 appearance. The specc. in Roum. F. Gall. 1835, under the name of 

 Dothidea excavata, C. & E. r are only the spermogonial stage of some 

 species unknown apparently not Dothidea.
