 aliont the same in size and shape as in the preceding species. Sac- 

 cardo in S\ lloirc savs i)eiitlioeia polvstichons, l)ut wo have never found 

 them so, though a vertical section through one side of the stroma shows 

 them apparently in more than one layer; lait this is only apparent, as 

 may 1)0 seen in a vertical section through the center of the sti'oma. 

 We find the asci ami sporidia altout as in the preceding species, though 

 in the Sylloge they are said to lie longer and narrower. This is dis- 

 tinguished from I), concentriv.a by its shiniug-hlack stroma, and the 

 looser texture of the radiate-fihrous inner substance which is cut hy 

 S-12 dark colored, memlu-anaceous horizontal layers or ])lates. These 

 are very noticeal)le in a vertical section even in the young i)lant, while 

 it is still covered with the eonidial layer and before the terminal, suli- 

 <f|ol)ose, ascigerous stroma has begun to appear. In the mature state, 

 the lil)rous inner substance and the horizontal mcndtranes disappear 

 to a greater or less extent, and leave the stroma more or loss hollow, 

 <o that it may be easily crushed with the fingers, but in D. convent rica 

 the inner substance remains firm and is also of a darker color.
