drical, thick, stout, obtuse, with an irregular opening ; asci broad- 

 lanceolate, sessile, .oo3'x.ooo6'; sporidia biseriate, oblong-elliptical, 

 hyaline, uniseptate and slightly constricted at the septum, .0005'x 

 ,0003', with two large transparent nuclei, at length separating in the 



middle- 



The bark of the limb finally decays and falls away, leaving the 

 tuberculiform stroma adherent to the surface of the wood. 



On dead limbs of Amelanchier Canadensis. April. 



LOPHIOSTOMA TiNGENs. — Perithecia buried in the wood, mostly 

 compressed, thick and leathery and of medium size; ostiolum barely 

 visible on the surface, not projecting and only slightly compressed; 

 asci cylindrical, .oo35'x.ooo4'; paraphyses linear; sporidia uniseriate, 

 oblong, obtuse, brownish, 3-septate, with a longitudinal septum more 



or less distinct, often slightly curved, variable in length, mostly about 

 ,0007'x. 000275'. 



On dry, decorticated maple limbs. February. 



Sphaerta FUNicoLA. — Scattered, minute, ovate-globose, seated 

 among the fibres of cotton; ostiolum not prominent; asci turgid-cyl- 

 indrical, .oo25'x.ooo7'; paraphyses connate and brown above; spo- 

 ridia biseriate, oblong-elliptic, hyaline, 3-septate, slightly curved, 

 .00075' — .ooo8'x.ooo3'. 



On old cotton twine, exposed on a grape trellis. lona, N. J. 

 January, Rev. Isaac Leonard. 



Sphaerta latebrosa. — Perithecia minute, gregarious, sub-glo- 

 bose, covered by the epidermis, which is elevated and blackened above 

 and soon pierced by the subconic ostiola; asci clavate-cylindric, 

 about .0035' long; paraphyses filiform, abundant, interwoven, longer 



than the asci; sporidia biseriate, fusiform, slightly curved, 4-6-nucle- 

 ate, about .00 1' long. 



On basal sheaths of old Andropogon. September. 



Sphaeria (Diaporthe) gallophila, — Densely gregarious, peri- 

 thecia sub-cuticular, depressed-hemispheric, .0009' — .001' diameter, 

 rugose; ostiola cylindric, obtuse, minutely roughened, .0006' — .oox' 

 long; sporidia biseriate, oblong-fusiform, hyaline, 2-4-nucleate, and 

 mostly constricted, when young faintly appendiculate at each end, 

 slightly curved, variable in length, .0005' — .0007' long. 



The part of the matrix occupied by the fungus appears to the 

 naked eye as if covered with a black pubescence, so thickly is it dot- 

 ted with the hair-like ostiola. 



On dead canes of Rubiis villosus, September. 



Sphaeria (Leptos.) defodiens. — Perithecia depressed-globose, 

 .0085' — .01' diameter, covered with- fragments of the ruptured epi- 

 dermis, at length deciduous; ostiolum subglobose, large, prominent ; 

 asci broad, clavate-cylindric; paraphyses abundant; sporidia biseriate, 

 fusiform-oblong, hyaline, 3-5-septate and at length constricted at 

 the septa, .0008' — .oot2'x.ooo2' — ^.0003', with an apical bristle-like 

 appendage when young. 



On /uncus. lona, N. J. September, 



Sphaeria (Leptos.) Mertensiae.— Subcuticular; ostiola papilli- 

 form ; asci_ clavate-cylindric, .003' — .oo4'x.ooo6' — .0007'; sporidia 

 crowded, linear-lanceolate, yellowish, nucleate, uniseptate at first,
