Diatrype Texensis, E. & E.—On bark of fallen iiinbs of (Tilia Y). 
Houston, Texas, April, 1869. H. W. Ravenel, No. 180. Stroma subcai- 
bonaceous, black, suborbicnlar, 2—4 millim. across, at length plane, oi- 
subconcave above, seated on the surface of the inner bark and bursting- 
through the epidermis which closely surrounds it; perithecia coriaceous, 
with thick walls, globose, or subangular by pressure, 6—20 in each 
stroma, i—.4 millim. in diameter; ostiola subtuberculiform, or hemis¬ 
pheric, with a rather large, though indistinct opening; asci clavate- 
cylindrical, about 75 x 12 with abundant paraphyses; sporidia partly 
biseriate, yellowish-brown and 1-septate at first, becoming dark-brown 
and 3-septate, ovate or oblong-elliptical, 15—20 x 6—7 /'-, scarcely con¬ 
stricted at the septa, the terminal cells subhyaline. Has much the same 
general appearance as D. cincta, B. & Br. The bark and the surface of 
the wood beneath the stroma is more or less blackened. This would 
come under Saccardo’s genus Thyridaria. 
Valsa (Calosph^ria) hylodes, E. & E. (Grk. hylodes, bushy.)— 
On smooth bark of a decaying log. JLouisiana, Nov., 1885. Rev. A. B. 
l.<anglois, 111. Perithecia membranaceous, globose, 4—f millim. in di¬ 
ameter, in clusters of 4—6, buried in the scarcely altered, librous sub¬ 
stance of the inner bark, their stout, cylindrical, roughish, black ostiole, 
i millim. long, pierced with a small aperture at the smooth, rounded 
apex, bursting through the epidermis (which is not split or torn) in little 
fascicles, with numerous light-brown, coarse, tow-like hairs as long or a 
little longer than the ostiole, and causing the surface of the bark to ap¬ 
pear as if covered with clumps of miniature bushes. The ostiola are of 
a carbonaceous character, as they readily break square olf, so as to appear 
truncate. The clusters of perithecia lie in parallel series, or lines, ex¬ 
tending for three or more centimeters, and the epidermis, which remains 
closely attached, is scarcely elevated by the subjacent perithecia. Asci 
clavate, with a slender, thread-like base, spore-bearing part 18—22 x 5 y, 
with the upper part broader and obtuse. Sporidia cylindrical, hyaline, 
or with a faint yellow tint, rather strongly curved, about 5—1 y, with a 
faint nucleus near each end. 
Lophiostoma Floridanum, E. & E.—Parasitic on old Diatiype 
stigma. Florida, Jan., 1886. VV. W. Calkins, Nos. 128, 147. Perithecia 
gregarious, or scattered, hemispherical, black and rough, about i millim. 
in diameter; ostiolum linear, extending quite across the apex of the per- 
ithecium, but scarcely prominent. Asci clavate, cylindrical, 80 x 8 y, with 
an elongated, slender base and surrounded with abundant tiliforrn para¬ 
physes. Sporidia biseriate, fusiform, slightly curved, olivaceous, 4-nu- 
cleate, uniseptate, constricted at the septum, just above which they are 
slightly swollen, 18—20 x 4—44 !’-■ The matrix is overrun with a hypho- 
mycetous growth, which also embraces the base of the perithecia, but 
vve can not say whether this is accidental. This is quite distinct from 
Oothidea episplneria. Pk., and Splneria nigerrima. Blox.
