NEW SFECJES OF FUNGI. 23 



^oward each end, straight or slightly curved, multinucleate, at length 

 obscurely multiseptate, greenish-yellow, .0025 to .003 in. long, .00012 

 to .00016 broad. 



Decaying wood of hemlock. Adirondack mountains. August. 



This is Sphceria scopula C. & P. in the Thirty -second Report. It 

 is here referred to the genus Acanthostigma because of the shape of 

 the spores. From A. Clintonii it may be distinguished by its larger 

 perithecia and longer spores. 



Lasiosphaeria iutricata. 



Perithecia scattered or crowded, somewhat elongated, .025 to .035 

 in. long, .018 to .02 broad, generally narrowed toward the base, 

 obtuse, subfragile, tomentose-hairy, brown or blackish-brown ; subi- 

 culum very thin or none ; asci slender, elongated, .005 to .008 in. 

 long, .0004 to .0005 broad ; spores crowded, linear, curved or flexu- 

 ous, greenish-yellow, .0016 to .0025 in. long, .00016 to .0002 broad. 



Decaying wood and leaves in damp places. Sandlake. 



The species belongs to the section Leptospora. The perithecia, 

 though small, resemble in shape those of Bombardia fasciculata. 

 The minute papillate ostiolum is often concealed by the tomentum of 

 the perithecia. This is composed of intricate, matted, slender, sep- 

 tate, brown filaments, which, by their soft, tomentose character, read- 

 ily distinguish this species from the related L. strigosa, L. kzspida, 

 L. hirsuta, etc. 



Herpotrichia leucostoma. 



Perithecia small, .012 to .018 in. broad, numerous, somewhat 

 crowded, subglobose, seated upon or involved in a blackish-brown 

 tomentum, the ostiola naked, not prominent, whitish when moist, 

 grayish or sordid when dry ; asci cylindrical or subclavate, .006 to 

 .008 in. long, .0004 to .0006 broad ; spores crowded or biseriate, 

 oblong-fusiform, at first uniseptate, constricted at the septum and 

 containing two or three nuclei in each cell, then three to five-septate, 

 colorless, .0015 to .002 in. long, .0003 to .00035 in. broad. 



Dead branches of mountain maple-bush, Acer spicatum. Catskill 

 mountains. September. 



The whitish ostiola constitute a marked feature in this species. It 

 is distinguished from Herpotrichia Schiedermayeriana Fckl. by its 

 much smaller perithecia, and the more numerous septa of the spores. 

 I have observed no globose appendages at the ends of the spores in
