ecous, more or less roslrat*'. Asri .s-spored. Sporidia elongated 

 Iransversrly plnriseptale, <ubhyaline or rarely brownish. Paraphyses 

 distinct. 



C. inicrodoma, E. & E. Journ. Myeol. IV, p. 78. (Plate 22) 



Peritliecia barely covered by the bark, densely gregarious, minute, 

 not over 165 p. diam. Ostiola projecting, cylindrical, J nun. long, rough 

 and more or less overrun with a brown tomentuin (which, however, 

 may be only accidental). Asci oblong-cylindrical or clavate-cylin- 

 drical, 50-55 x 7-8 //. subsessile. with rather stout, filiform paraphyses. 

 Sporidia biseriate or crowded, oblong or clavate-oblong, 3-septate and 

 slightly constricted at the septa, olive-brown, ll-12x 2|-3 /2.

OPHHWERAS, Sacc. 



Syll. II, p. 358. 



Peritliecia immersed or emergent, subcarbonaceous, globose, with 

 a conic-cylindrical ostiolum more or less elongated. Asci subcylin- 

 drieal. Sporidia filiform or cylindrical, 2- or more-septate, hyaline. 



This genus differs from Ceratostoma in its elongated, hyaline, 

 septate sporidia. 



0. Ohiense, E. & E. (in Herb.) 



Peritliecia gregarious, at first immersed in the wood which is 

 slightly pustulate-elevated over them and pierced by the stout, black, 

 rough, beak-like ostiola, which are 1-2 mm. long, carbonaceous and 

 brittle, their smooth, rounded tips at first pierced in the center with a 

 small, round opening, at length broadly perforated. The perithecia 

 are finally emergent and bare, only the base remaining sunk in the 

 wood, about 1 mm. diam., with thick, carbonaceous walls, rough and 

 brownish-black outside, the upper, projecting part finally breaking or 

 falling away, leaving only the cup-shaped base sunk in the surface of 

 the wood. Asci clavate-cylindrical. gradually attenuated below, 90- 

 100x7-8 IJL, pseudo-paraphysate, 8-spored. Sporidia subfasciculate, 

 fusoid-cylindrical, hyaline, 8- 12-septate, slightly and rather abruptly 

 attenuated at the ends, which are mostly a little incurved and sub- 

 obtuse, 40-50 x3J-4 //. 



On rotten wood, Ohio (Morgan, No. 528). 



This seems to be (piite distinct from any other described species.
