SPHiEKELLA GRANULATA, E. & E.—Oil dead steins of Baptisia 
tmctoria^ with Sphcerella bapUsicecola, Ck., iSTewfleld, N. J., April, 1886. 
Densely gregarious, occupying a delinitely-limited area of the stem ; per- 
ithecia minute (one sixth millim.), covered by the epidermis, which is rais¬ 
ed and fissured over them, but not blackened, though the black perithecia 
are visible through it; ostiolum papilliform, only slightly prominent; 
ascigerous nucleus, white ; asci nearly cylindrical, about 70 x 7 p subses- 
sile, without paraphyses, and containing eight biseriate, fusiform, 
slightly curved, hyaline, granulate at first, then uniseptate, sporidia 
20—23 X 3—3i l^. The specimens found grow around the base of the stem, 
extending up for about 2 inches, where it was abruptly succeeded by 
Sphcerella haptisicecola, Ck., iu which the perithecia are more scattered 
and the sporidia shorter (12—16 /^-), broader (4— 5 !-•■) and continuous. The 
specimens of this latter species, in Kav. F. Am., are not well developed 
and have the spores narrower (3—3i P) and more acute, as described by 
Cooke. 
Dimerosporium xylogenum, E. & E,—On decaying wood of Salix. 
Louisiana. Langlois,No. 371. Perithecia superficial,scattered, depress¬ 
ed-hemispheric, rough, one sixth to one fourth millim., with an obscure, 
papilliform ostiolum ; asci obovate, contracted below into a short stipe, 
35—40 X 20—24 /^, without paraphyses, and containing 8 oblong-elliptical, 
1- septate, granular, subhyaline, 15—16 x 8 p- sporidia. Differs from the 
usual type of Asterina and Dimerosponum in its habitat and the absence 
of any definite mycelium. 
Dimerosporium Spartina^, E. & E.—On dead lower sheaths of 
Spartina polystachya, Plaquemines Co., La., May. Langlois, No. 428. 
The mycelium forms small (2—4 millim. long), oblong or elliptical, black 
patches, consisting of a thick growth of erect, simple, septate, subnodu- 
lose, sterile hyphse, nearly hyaline at first, but soon opaque, 130—175 x 
6—8 P, and pale, yellowish, prostrate hyphse, producing fusoid-cylindric 
or subfalcate, nucleate conidia, 40—60 x 3 p. Nestling among the sterile 
hyplue are black, membranaceous, subovate perithecia, i—i millim. in 
diam., with a very large (opening above ; asci clavate-cylindrical, 75 x 15 
p, with imperfectly-developed paraphyses ; sporidia 8 in an ascus, oblong- 
cylindrical, yellowish (nearly hyaline), slightly curved, 3—4-nucleate, 
becoming uniseptate, 18—20 x 4—5 P. Some sporidia were seen im¬ 
perfectly 3-septate, but one septum seems to be the normal state. This 
is remarkable for the large apical opening, more like a half-grown Cenan- 
gium than like an ostiolum. 
Didy^mosph^ria pardalina, E. & E.—On dead stems of Sjoartina 
polystachya. May. Langhus, No. 429. Perithecia gregarious in groups of 
4—0, whose position is indicated by suborbicular or elliptical, black spots, 
2— 4 millim. in diam., or by confluence more entirely sunk in the substance 
of the stem, ratlier large {i millim.), with thick, coriaceous walls and mi¬ 
nute punctiform ostiolum, not elevating the epidermis ; asci cylindrical, 
150—200 X 12—15 P ; sporidia uniseriate, oblong-cylindrical, olive-brown, 
l-septate and constricted, slightly curved, ends obtuse, 22—30 x 8—10 /^.
