NATURAL HISTORY BULLETIN. 



brown, oblong-ellipitical cells not very readily separating, con- 

 stricted between the cells, 7-9x3,". Occasionally the cells- 

 are subcubical. Contents of the mature perithecia black. 

 This differs from the Iowa specimens in the presence of a 

 subiculum, smaller, flatter stromata, and rather larger sporidia, 

 but can hardly be distinct. The Iowa specimens were not 

 fully matured. 



9. SCHIZOSTOMA STUPEUM E. & E. 



Perithecia gregarious, ovate-conical, $£ mm. high, y 2 mm. 

 thick, erumpent-superficial, brown, attached to the matrix by 

 radiating, straight, tow-colored hairs; ostiolum thick, stout, 

 short-cylindrical, obtuse, scarcely compressed, or with a short, 

 narrow, erumpent, compressed beak, the black tip rising from 

 the subtruncate apex; asci cylindrical, 75-85x4^, paraphysate, 

 8-spored; sporidia uniseriate, oblong, brown, uniseptate and 

 slightly constricted, straight or very slightly curved, 9-1 2 x 



3-3 }^- 



On rotten wood, Black Water River, Nicaragua; March, 

 1896. (C. L. Smith, No. 6.) 



10. Nectria ch^tostroma Ell. & Macb. 



Perithecia cespitose, globose, y$ mm. in diam., glabrous, 

 dull red, becoming reddish brown, collapsing above, surrounded 

 by a subiculum of brown, septate, crooked hairs 100-200" 

 long and about 3« thick; ostiolum distinctly papilliform; asci 

 clavate-cylindrical, 50-60x8-10", subsessile, paraphysate, 

 8-spored; sporidia biseriate, oblong, slightly curved, 2-nu- 

 cleate, constricted-uniseptate, pale brown, obtuse, 13-16x5- 

 51^/". The first appearance is a tuft of dark brown hairs, 

 which are finally hidden and almost obliterated by the densely 

 crowded perithecia 10-40 in number in a compact group 1-4 

 mm. across. 



On bark of some undetermined shrub or tree, Ometepec, 

 Nicaragua.
