conic ostiola dotting the surface of the stroma. Asci cylindrical, spore- 

 bearing part 30-35 x 3 /«, with a slender, thread-like base about 20 n 

 long. Paraphyses not observed. Sporidia uniseriate, yellowish- 

 hyaline, 8 in an ascus, globose, 3 fj. diam. Outwardly, this is scarcely 

 distinguishable from D. minima, but the marked difference in the. 

 sporidia seems to entitle it to specific rank. The stroma in some of 

 the specimens is limited by a black line, as in D. minim,a, but in 

 others not.
