surrounded by a black line, and sometimes as much as 8 mm. diam., 

 hypopliyllous, immersed, about 100 ;i diam., thin-membranaceous, the 

 apex perforating the epidermis. Asci clavate, very short-pedicellate, 

 8-spored, 50-70 x 9-11 /j., with thick, cylindrical, septate paraphyses. 

 Sporidia biseriate (rarely uniseriate), oblong, inequilateral, attenuated 

 at each end, uniseptate, constricted at the septum, brownish, 14— 

 16x5 //.

D. serrulata, E. & M. Journ. Mycol. I, p. 99. 



Perithecia scattered or gregarious, covered by the cuticle, len- 

 ticular, |-J mm. diam. Asci cylindrical, 100-112x10-12 n, with 

 abundant, linear paraphyses. Sporidia uniseriate, hyaline at first and 

 3-nucleate, soon becoming dark brown and uniseptate, 18-20 x 5-6 /i, 

 surrounded at first with a hyaline envelope. The sporidia are much 

 like those of Anthostomella leticobasis, E. & M., only longer and uni- 

 septate, and the perithecia are larger and more pi'ominent.

Perithecia minute, punctiform, subglobose, covered by the epi- 

 dermis, which is pierced by the scarcely papillate ostiola.. Asci 

 cylindrical, 55-80x71-10 /i, with filiform paraphyses. Sporidia ob- 

 long or elliptical, uniseriate, uniseptate, not at all, or but slightly con- 

 stricted at the septum, colored, 10-15 x 5-7 fi.

Perithecia scattered, covered, but prominent, small, smooth, at 

 length collapsed and flattened. Ostiolum minute, erumpent. Asci 

 cylindrical, 75-100x7-8 /i, with branching paraphyses, 8-spored. 

 Sporidia uniseriate, rarely subbiseriate, biconic-elliptical, uniseptate, 

 constricted, colored, straight or curved, 2-nucleate, 8-11 x 6 /z. Very 

 variable, especially in the size of the sporidia. A form occurs (on 

 bramble stems) with the asci mostly tetrasporous.
