Perithecia gregarious, or crowded, sub-obovate, yz-^i mm. 

 dia., obtusely rounded and white pruinose above, except the 

 minute, papilliform, black ostiolum, black below and connected 

 by a thin, black crust. Asci (p. sp.) cylindrical, about 50X 5 ^, 

 paraphysate, 8-spored. Sporidia uniseriate, inequilaterally 

 elliptical, brown, finally opake, continuous, 8-10X4,". 



On wood, Ometepe. (C. L. S.) 



R. ? 



Old specimens without fruit. This might be a Lasiosphcs-

Melanopsamma shimekii E. & E. n. sp. 



Perithecia gregarious, superficial, ovate-conic, about ^ mm. 

 dia., brownish-black, and, except the smooth, black, conic- 

 papilliform ostiolum, muricately roughened and clothed with 

 scattered, short, pale, glandular hairs. Asci clavate-cylin- 

 drical, short stipitate, 1 50-180 x 12-15//, 8-spored, overtopped 

 l)y the abundant, fiHform paraphyses. Sporidia crowded- 

 biseriate, fusoid, uniseptate and constricted, slightly curved, 

 .48-57x10-12//, 3^ellowish-hyaline, ends at first acute, then 

 sub-obtuse. 



M. papilla (Schw.) and Af. ohtasissima (B. & C.) come 

 nearest this but both have smooth perithecia. 



On dry, hard wood, Ometepe. (B. S.) 



Melanomna subconicum E. & E. n. sp. 



Perithecia depressed-conic-hemispherical, erumpent-super- 

 ficial, covered by the blackened epidermis, scattered, about 

 I mm. dia., sub-angular; ostiolum papilliform. Asci cylin- 

 drical, lOoXiOjU (p. sp. 00-70 // long), with abundant, filiform 

 paraphyses, 8-spored. Sporidia uniseriate, oblong-elliptical, ob- 

 tusely pointed and with a small hyaline protuberance at each 

 .end, obscurely 3-4-pseudo-septate, 12-15x6-7//, olive-brown.
