Leptosphaeria Corallorhizae, n. sp. 



Plate 2, figs. 20-23. 



Perithecia numerous, minute, .004 to .005 in. broad, erumpent, black, 

 with a minute ostiolum ; asci cylindrical, sessile, .002 to .003 in. long, 

 .0003 to .00035 broad ; spores crowded or biseriate, subfusiform, trisep- 

 tate, slightly constricted at the middle septum, yellowish-brown, .0008 

 to .001 in. long, .00016 to .0002 broad. 



Dead stems of Corallorhiza multifiora. Caroga. July. 



Leptosphaeria eutypoides, n. sp. 



Perithecia numerous, closely gregarious, .01 to .011 in. broad, hemi- 

 spherical or depressed, at first covered by the epidermis, then naked, 

 black, ostiola papilliform ; asci clavate or subcylindrical, .004 to .0045 in. 

 long, .0005 to .00065 broad ; spores ovate or oblong, straight or slightly 

 curved, triseptate, usually constricted at the septa, yellowish-brown, 

 .0008 to .0009 in. long, .0003 to .0004 broad, paraphyses filiform. 



Dead stems of large herbs, as Chenopodium album. Albany. . May. 



The matrix becomes blackened, which, with the nearly uniform dis- 

 tribution of the numerous perithecia, is suggestive of the appearance 

 of some species of Eutypa. 



Leptosphaeria lycopodiicola, n. sp. 



Plate 2, figs. 16-19. 



Perithecia small, .005 to .006 in. broad, sphseroid or elliptical, erum- 

 pent, black ; asci subcylindrical, nearly sessile, .0025 to .003 in. long, 

 .0003 to .0004 broad ; spores oblong or subfusiform, slightly colored, 

 three to five-septate, .0008 to .001 in. long, .00016 to .0002 broad. 



Dead peduncles of Lycopodium clavatum. Adirondack mountains. 

 June. 



The perithecia are associated with a minutely tufted, blackish Clados- 

 porium. Some of them are laterally compressed. The covering epi- 

 dermis generally ruptures longitudinally. The spores are much more 

 narrow in this than in L. Crepini and L. Marcyensis, both of which in- 

 habit species of Lycopodium. 



Metasphaeria Myricae, n. sp. 



Plate 2, figs. 24-27. 



Perithecia numerous, broadly conical, .016 to .021 in broad, covered by 

 the thin closely-adhering, epidermis, black, white within, ostiola pertuse ; 

 asci clavate, obtuse, .004 to .005 in. long, .0006 to .0008 broad ; spores 

 crowded or biseriate, oblong or subfusiform, straight or slightly curved, at 

 first uniseptate, quadrinucleate, strongly constricted at the middle sep- 

 tum, finally triseptate, colorless, .0012 to .0016 in, long, .0004 to .0005 

 broad ; the paraphyses numerous, conglutinate. 



Dead branches of Myrica Gale lying partly in water. Caroga. July. 



The epidermis is so closely adherent that the perithecia appear as if 

 superficial or merely innate at the base. The nuclei of the spores are 

 large. Spores with three septa are rare, but this may be due to the 

 immature condition of the specimens.
