 paraphysate, 8-spored. Sporidia bi-seriate, acutely elliptical^ 

 hyaline, 2-nucleate, 6-8x2 3^//. 



Tr. fidchriseta (Pk.)i has about the same sporidia but the 

 perithecia are more scattered and much smaller. T?'. ^ilosa 

 (Pers.) has also much smaller perithecia and the sporidia (see 

 Winter's fig.) are different. 



On bark, Omet^pe. (B. S.) 



Herpotrichia diffusa {^Sdnv.') E. & E. 

 On decaying bark, Castillo Viejo. (C. L. S.) 



H. nicaraguensis E. & E. n. sp. 



Perithecia superficial, densely gregarious, ovate, }4-^X 

 }i-}4 mm., rough, pruinose-pilose at first, soon bald. Ostio- 

 lum broad-papilliform, soon broadly perforated. The asci, in 

 the specimens seen, had disappeared. Sporidia oblong-ellip- 

 tical, uniseptate, not constricted, hyaline at first, then olive-

 slightly prominent ostiolum. Asci cylindrical, 78x6-8// (p. 

 sp.), stipe 30-40 ,« long. Sporidia 8, monostichous, ellipsoidal, 

 soon inequilateral, 2-guttulate, fuscous, 10-12x5-6//. Para-
