 B. propiillans, (Schw). 



Sphceria propullans, Schw. Syn. N. Am. 1447. 

 Botryospharia propullans, Cke. Syn. 1434. 



Black, seated in the inner bark, and erumpent through the epi- 

 dermis, by which it is closely surrounded, subrotund, base contracted, 

 subturbinate, seated on a scanty stroma. Perithecia rather large, 

 prominent, subdepressed, crowned with a papilliform, central ostiolum. 

 Tufts of perithecia numerous, appearing punctate-rugose above. 



On much decayed stems of Celastrtis, Bethlehem, Pa. (Schw.). 



The diagnosis (taken from Schw. Syn.) is obscure, and the species 

 doubtful. There is no spec, in Herb. Schw.

Syll. I, p. 6oo> 



Perithecia botryose-aggregated, erumpent-superficial, glabrous, 

 white inside, seated on a depressed-pulvinate, rather soft stroma also 

 whitish within. Asci cylindrical, paraphysate, 8-spored. Sporidia 

 ovoid-oblong, uniseptate, hyaline. 



M. endoleiicum, Sacc. Mich. II, p. 138. 



Acervuli gregarious, subsuperficial, depressed-pulvinate, J-J mm. 

 diam., very black outside, but the nuclei of the perithecia and the 

 inside of the stroma white. Perithecia slightly sunk in the stroma, 

 subglobose, obtuse, tuberculose-prominent, texture parenchymatic, dark 

 brown. Asci cylindrical, very short-stipitate, rounded at the apex, 

 90x5-6 fi, paraphyses grumose-deliquescent. Sporidia uniseriate, 

 ovoicloblong, 10-13x5-6 /*, 2-nucleate, uniseptate, not constricted, 

 hyaline.

" Spots bursting out transversely, but generally orbicular, very 

 rough with the conical, rugose, pulverulent ostiola. Asci clavate. 

 Sporidia hyaline, in one or sometimes two rows, oblong, sometimes 

 narrower below, obtuse, 25 p. long. Looks at first sight like a 

 Dichcena."
