 M. graopsis, (Ell. 



SphcsHa graopsis, EU. Bull. Torr. Bot. Club. IX, p. 73. 

 Melanopsamma graopsis, Sacc. Syll. 6066. 

 Exsicc. EU. N. A. F. 780. 



Perithecia scattered, erumpent, submembranaceous, globose or 

 subelongated, partially collapsing above, 250-370 (x diam., rough and 

 more or less covered with the bleached fibres of the wood. Ostiolum 

 ]'apilliform, slightly prominent, surrounded by a slight depression. 

 Asci oblong, mostly bulging on one side, sessile, 50-58 x 20-25 //, with- 

 out paraphyses?, 8-spored. Sporidia irregularly crowded, oblong-ellip- 

 tical, or oblong-navicular, hyaline at first, becoming pale yellowish- 

 brown, uniseptate, 20-25 x 8 //.

M. Eckf^ldtii, (Ell.) 



Sphisria Eckfeldtii. Ell. Bull. Torr. Bot. Club VIII, p. gi. 

 Melanomma Eckfeldtii, Sacc. Syll. 3247. 

 Exsicc. Ell. N. A. F. 593. 



Perithecia scattered, erumpent, minute (200-250 // diam.), carbon- 

 aceo-coriaceous, glabrous, subglobose, with a minute, papilliform osti- 

 olum. Asci oblong or obovate, sessile (paraphysate) ? 70-80x25-30//. 

 Sporidia inordinate, oblong or oblong-fusiform, yellowish-hyaline, uni- 

 septate, sometimes a little curved, 25-30 x 6-9 ^i. 



On bleached wood of chestnut, near Philadelphia, Pa. (Eckfeldt). 



A more careful examination of the original specimens shows that 

 the sporidia do not become 3-septate and brown, as was at first stated. 

 Three-septate, brown, free sporidia were seen, and it was too hastily 

 (•oncluded that these were the mature sporidia, when, in fact, their 

 presence was only accidental.

Perithecia scattered, black, opake, symmetrically rounded, hemi- 

 spheric-conical, innate, large (1 mm. diam.). Ostiolum papilliform. 

 Asci cylindrical, p. sp. 200-230 x 15-20 //, with a short, abrupt stipe 

 about 25 fi long, and abundant filiform paraphyses. Sporidia uni- 

 seriate, oblong-elliptical, hyaline, 30-50 x 15-18 n, slightly constricted, 

 2-nucleate. 



On rotten maple wood and bark, Carolina, on outer bark of living
