patches 1-2 inches across, the branches crowded so as to entirely 

 cover the subicnlum, narrowly cleft, lips mostly closed. Asci cylin- 

 drical, 75-80x10 /i, short-stipitate, paraphysate. Sporidia 8 in an 

 ascus, overlapping-subbiseriate, fusoid, hyaline, uniseptate and con- 

 stricted at the septum, 20-22 x 5-6 /i. 



On rotten wood, northern United States and Canada, and south 

 to Carolina; probably to be met with in other parts of the country. 



The large patches of radiate perithecia are generally made up of 

 several smaller, orbicular patches, 3-4 mm. diam., confluent at their 

 adjacent margins and presenting a very neat appearance. 



G. accumu latum, Schw. Syn. N. Am. 2016. 



Subiculum scanty around the margin, coarsely fibrillose, about 

 one inch across, rising in an irregular, truncate-pyramidal shape, very 

 uneven and rough, on account of the ramose-radiate perithecia being 

 crowded and lying one above the other; half an inch thick. Color 

 the same as in the preceding species. 



On rotten wood, Bethlehem, Pa, (Schw.). 



Apparently a mere var. of G. stellatum, but regarded by Schw. 

 as distinct.

Exsicc. EH. N. A. F. 1283. 



Emergent, oblong, 1-2 mm. long, ends obtuse, lips incurved, dis- 

 tant, smooth, leaving the sooty disk more or less permanently exposed. 

 Asci clavate-cylindrical, sessile, 80-90x9-12 ju, overtopped by the 

 densely crowded paraphyses whose closely matted, dark-colored tips 

 give the sooty color to the disk. Sporidia uniseriate or partly 

 biseriate above, ovate, uniseptate, hyaline, 12-16x5-7 /a. In the 

 fresh state the swollen disk entirely hides the margin. 



On old fence rails, Washington (Suksdorf ).

Perithecia more or less crowded, sometimes longitudinally con- 

 fluent, mostly lying parallel, subimmersed in the wood which is often 

 blackened, linear, rather flat, straight or flexuous, ends obtuse, black, 

 smooth, lips slightly swollen 1-1 \ mm. long, about J mm. wide. Asci 

 clavate-cylindrical, 75-90 x 12-14 /*. Paraphyses conglutinate, their 

 tips united above and forming a dark-colored, coarsely granular stra-
