 form, brown, 18-20 x 10 ft.

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

 idea concaviuscula, E. & E.. which agrees with this only in external 

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

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

 species unknown — apparently not Dothidea.

 Sporidia suboblong, 3-5-septate, yellowish.
