roughened by tlie blackish, rather large and prominent ostiola, 1—2 
inillim. in diam ; asci 90—110 x 12 !J- ; sporidia fusiform, slightly curved, 
3-septate, brown, 38—45 x 3—4i P-. Bioirype lateritia, Ell., Bull. Torr. Bot. 
('lub., IX, p. 19, and Hypoxylon myricmgioides^ B. & C.(?) N. A. E., 474, 
are tlie same as this. The same thing is also to be found in Roume- 
guere’s Eungi Gallici, No. 1174, on bark of Corylus, collected at Lyons, 
Erance. The young stroma, as already noted, is of a pale brick color, 
and is sometimes nearly plane above and at length more or less rugose 
and pitted from the collapsing of the upper part of the perithecia. 
Whether the Hypoxylon myriangioides, B. & 0., is really the same as this, 
we are still unable to say, but the description of that species in Grevillea 
renders such a supposition not improbable. 
52. Hypocrea citlortna, Cke. Grev. VII, p.49. Tiav. E. Am., 342. 
Elattened, discoid, elliptical or elongated, I—2 millim. in diam., clay 
colored (bright yellow within); perithecia immersed, brown, ostiola 
blackish, punctiform ; asci clavate, spore-bearing part about 75 x 15 y, 
suriounded with abundant tiliform paraphyses ; sporidia biseriate, nar¬ 
row-elliptical, endochrome three times divided, yellowish ( becoming 
brown ?), 20—25 x 8—9 !>■. On bark of hickory. Darien, Ga. The 
stroma is of about the same color as the bark. Hatter than in the preced¬ 
ing species, but of about the same color.

Stroma pulvinate, hemispheric, base constricted and orange-col¬ 
ored ; perithecia peripheric, erect, ovate and, with the punctiform 
ostiola, bright purple, sunk in the upper part of the stroma, which is of 
the same color; asci linear with the apex cap-shaped or obtusely conic; 
sporidia linear, curved, finally breaking up into segments 10—18 x 2 y. 
Oil living leaves of Cantarea Cayenne.'''' We have included this species, 
which will not irapiobably yet be found in Southern Florida or Mexico.

‘‘ Convex nr pulvinate. subconfluent, blackish externally, white 
within; seated on a whitish or gray subiculum ; ostiola prominent; asci 
very long and linear; spores elongated, filiform, multinucleate, color¬ 
less.” According to Farlow, in Bull. Bussey Inst., this is not distinct 
from Botliidea rorax, f>. &C.,of which B atramentaria, B. &C. (N. A. 
E., ()vS3), is only a variety, aiid we now suspect that Hphelis borealis, E. & E., 
.lourn. Mycol. I, p. 80, is only the stylosporous stage of the same thing. 
There is some uncertainty as to whether Peck or Berkeley has priority of 
publication, also as to the ti ne place of species in the systematic arrange-
