Peritliecia superficial, crowded, or sometimes scattered, ovate-glo- 

 bose, smooth, 400 n diam., black, firm but thin-walled, finally slightly 

 depi'essed around the papilliform ostiolum, at fii'st sparingly clothed 

 with conidia-bearing hairs. Asci clavate-fusoid, sessile, 8-spored, par- 

 aphysate, .60-75 (p. sp. 50-55) x 8-10 //. Sporidia biseriate, elliptical, 

 hyaline, uniseptate, 12-15x5-7 jx.

M. snbfasciculata, (Schw.) 



SphcEria snbfasciculata^ Schw. Syn. N. Am. 1565. 

 Psilosphizria subjasciculata , Cke. .Syn. 2991. 



Perithecia at first somewhat covered, but at length entirely de- 

 nuded. Allied to Bomhardia fasciculata, but more scattered and 

 longitudinally subseriate. Perithecia subfasciculate, black, rugose, 

 subindurated, sometimes shaped just like those of B. fasciculata, but 

 often less elongated, subrotuud and obtusely papillate, of smaller size 

 and subconfluent. Asci? Sporidia (sec. Cke. Grev. X\', p. 83) ellip- 

 soid, uniseptate, hyaline, 20 x 8 p..

Perithecia minute, densely crowded in patches, more scattered 

 circumferentially, mutually compressed, subspherical, 80-100 x 10-1 5 /i 

 ."-iporidia biseriate, uniseptate, subequal, 15-20x5 /./, hyaline.

M. abscondita, E. & E. (in Herb.) 



Perithecia liomispherical, obtuse, black, about J mm. diam., scat- 

 tered or crowded and subconnate, connected at base more or less dis- 

 tinctly by a thin, black crust, ostiolum papilliform, obscure. Asci 

 clavate-cylindrical, p. sp. about 75x12 p., with stout paraphyses. 

 Sporidia biseriate, oblong-fusoid, uniseptate, and strongly constricted _ 

 at the septum, slightly curved, nucleate, sometimes with two additional 

 septa, 20-22 x 5-G /a. 



Inside of old hickory nuts decaying on the ground. 



This has the outward appearance of Trernatosphoiria uvclenrki,
