our plant. The threads of the subiculum are obscurely septate and 

 sometimes slightly branched. The more classical name " leucostoma " 

 is here substituted for " albidostoma." 



Zignoella liumulina. 



Perithecia small, .011 to .014 in. broad, depressed-hemispherical, 

 slightly sunk in the matrix, subglabrous, black, with a minute papil- 

 late ostiolum ; asci cylindrical, .0025 to .003 in. long, .0003 to .0004 

 in. broad ; spores uniseriate or obliquely monostichous, elliptical, 

 four-locular, appearing obscurely triseptate, colorless, .0005 to .0006 

 in. long, .00025 to .0003 in. broad. 



Dead stems of hops, Humulus lupulus. Carlisle. June. 



The spores are not distinctly triseptate, and the species apparently 

 belongs to the subgenus Zignoina. The perithecia have a dull, 

 . squalid, unpolished or subscabrous appearance. 



Acrospermum album. 



Perithecia elongated, subfusiform, somewhat compressed, pointed 

 at the apex, narrowed below into a short, terete, stem-like base, 

 white ; spores very long, filiform. 



Dead stems of spikenard, Aralia racemosa. Catskill mountains. 

 July. 



This resembles A. compressum in size, but it is at once distinguished 

 from that and other related species by its persistently white color.
