papilliform and perforated, black. Asci cylindrical, 100x5 p (p. sp. 

 55-60x5//), paraphysate, 8-spored. Sporidia uniseriate, subinequi- 

 laterally elliptical, brown, 6-7 x 3 p. 



On bark of dead (oak)? limbs, Michigan (Hicks). 



Has the general appearance of II cohcerens and H. turbinu- 

 latum,, but the perithecia and sporidia are smaller than in either of 

 these species. The stromata are so much contracted below as to 

 appear only centrally attached.

Sphceria grisea, Schw. Syn. N. Am. 1252. 



Oblong, effused, subconcave, innate-immersed in the wood, acu- 

 minate at each end, surrounded by a deeply penetrating, black line, 

 tolerably thick in the middle, and whitish-gray, thinner towards the 

 margin. Perithecia numerous, flattened, very small, immersed in the 

 stroma. Ostiola subumbonate, obtuse, gray, prominent. The surface 

 of the stroma cracks into frustules. 



On decorticated wood, Bethlehem, Pa. (Schw.); rather rare. The 

 stroma is often an inch in diameter. The spec, in Herb. Schw. is 

 without fruit.

Stroma erect, thick, simple or forked above, round or rarely a 

 little dilated and compressed towards the summit, glabrous, becoming 

 black, base tuberous. Fertile head sterile at the apex, sometimes 

 3-parted, mammillose from the somewhat prominent, densely crowded 

 perithecia. Asci cylindrical, pedicellate, 8-spored, pseudoparaphysate. 

 80-84 x 6-7 p (p. sp.). Sporidia obliquely uniseriate, fusiform, obtuse, 

 inequilateral, brown, 12 x4 ju. 



On the ground, Carolina and Pennsylvania (Schw.). 



The following notes are from specimens in the Schweinitzian 

 Herbarium at Philadelphia: 



1203.* Sphceria afflata, Schw. The spec, in Herb. Schw. is a 

 mere sterile crust. 



1255. Sphceria enter oxantha, Schw. Looks like Hypoxylon 

 Sassafras, but immature or sterile no fruit.
