posed and sulisiiperficial, subgloViosc, about } mm. diam., with an 

 acntely papilliform ostiolum. Asci cylindrioal, 65-70 x 6-7 fi, par- 

 aphysate. Sporidia overlapping, uniseriate, fusoid, acute, nearly hya- 

 line and uniseptate at first, becoming subobtuse, brown and 3-septate, 

 18-20 X 4-5 fi, (30 X 6 ;/, Cke.).

Perithecia gregarious, membranaceous and of rather coarse, cel- 

 lular structure, about \ mm. diam., black, smooth, subspherical, at 

 length slightly collapsing above, at first covered by the epidermis, 

 finally erumpent. Asci oblong-cylindrical, about 100 x 20 ft, subsessile, 

 with evanescent, filiform paraphyses. Spoiidia biseriate, broad oblong- 

 fusoid, 1-2-septate, inequilateral and slightly curved, pale straw-yel- 

 low, constricted at the main septum, 22-30 x 7-9 //, (exceptionally 

 30-35 X 9-12 n), mostly 22-25 x 7-8 /i.

It is possible that fresh specc. might show the sporidia to be 

 appendiculate, in which case this would be referable to Ceriospora, 

 but, as far as can be seen in the specimens examined, there are no 

 appendages on the sporidia, though while lying in the asci their ends 

 are acute. The sporidia, as a rule, are only 1-septate, the 2-septate 

 sporidia being only occasionally seen.

Mataspharia Thalictri, Sacc. SyU. II, p. 156. 



Perithecia scattered or gregarious, for a long time covered by the 

 epidermis, strongly depressed-spherical, black, with the very small, 

 papilliform ostiolum scarcely projecting. Asci fasciculate, oblong, 

 mostly broader below, sessile, 8-spored. Sporidia pyriform, 2-septate, 

 the terminal cells mostly larger than the middle one, ends rounded, 

 slightly constricted at the septa, pale yellow, 21-23x10 /^. Par- 

 aphyses filiform, articulated.

The asci in the Greenland specc. were 70-75 x 20-24 //; sporidia
