Centrai. American Pyrenomycetes. 401 



On decaying wood, Castillo Viejo. (C. L. S.) In one case, 

 the substratum of the wood was very darkly colored and in 

 another scarcely colored at all. 



R. GIGASPORA E. d- E. n. sp. 



Gregarious, superficial, conic-hemispherical, i-i}4 mm. dia., 

 sessile, with a broad, flattened base, surrounded apparently at 

 first by a thin, brown, hairy subiculum spreading over the 

 surface of the wood and clothing the lower part of the peri- 

 thecia. Ostiolum globose -papilliform, black and smooth. 

 Sporidia broad-fusoid, brown, 55-62 x 10-12 ,«. The speci- 

 mens were past their prime and the asci had disappeared. 



On dead cane (?) stalk, Castillo Viejo. (C. L. S.) 



R. GiGAXTEA E. ct- E. n. sp. 



Perithecia gregarious, globose, sessile, 21^^-3^ mm. dia., 

 covered with a granulose-pruinose coat at first, except the 

 black, conical ostiolum, at length bare and reddish-brown, 

 often marked around the base of the ostiolum with short, sub- 

 radiate furrows; wall double, outer carbonaceous, firm, ^ mm. 

 thick, inner membranaceous. The perithecia are surrounded 

 by a growth of dark-brown, bristle-like fascicles of closely 

 compacted, reddish-brown, rather distantly septate hyphse 

 about 2 mm. high, arising from a sub-crustose subiculum; 

 oblong-elhptical, hyaline, 5-6x2-3// conidia were associated 

 with the bristle-like fascicles of hyphce, but the mode of at- 

 tachment was not seen. Asci cylindrical, p. sp. 2 50-270 x 8, m, 

 paraphysate, 8-spored. Sporidia overlapping uniseriate, fus- 

 oid, slightly curved, acute, with two large oil globules, oliva- 

 ceous at first, then opake, 40-62 x 6-8 ,«. 



E. dcsmazierii (B. & Br.j has smaller perithecia and spor- 

 idia, and R. bunodes (B. & Br.) has the perithecia rather 

 smaller, the sporidia more attenuated at the ends, and conidia 

 moniliform.
