and oblong elliptical, at first pale brown and 3—4—septate with 
the ends subacute, soon 5—7—septate and darker with the ends 
obtuse, one or two of the cells divided by a longitudinal septum 
which finally runs through all but the terminal cells, more or less 
distinctly. This is very distinct from P. velata Sacc. & Roum. 
in F. Gr. 1081 in its much larger perithecia which are not flattened 
and in its mostly longer 3—7—septate sporidia. Dr. Berlese in 
his fine monograph of Pleospora figures P. Saccardiana (of which 
he gives P. velata as a syn.) with 4-septate sporidia though he 
says the normal number is three as we find them in our copy 
of F. Gr. 
Pyrenophora hyphasmatis, E. & E.—On exposed cotton cloth. 
St. Martinsville, La., July, 1888. Langlois 1433. Perithecia 
gregarious, superficial, flask-shaped, mouse-colored, 340—370micr. 
diam, clothed except the broad, truncate ostiolum with brown, 
sparingly branched and sparingly septate, short, soft, somewhat 
crisped and matted hairs. Asci clavate-cylindrical 65—70x 6-7 
including the slender base, (p. sp. 50—55 micr. long), with abundant 
paraphyses. Sporidia crowded-biseriate, brown subnavicular 
with the ends at first subacute, 3-septate with occasionally one of 
the cells longitudinally divided 12—15 x 5—7 (mostly 12x6 micr). 
This has the general appearance of a Chsetomium. 
Ophtobolus consimilis, E. & E.—On dead stems of Ochra. 
Louisiana. Langlois No. 1312. Perithecia as in 0 . porphyrogonus 
gregarious on dull-red spots but not exclusively confined to them, 
smaller than in that species (about 200—250 mm.), sunk in the 
.substance of the matrix their obtusely conic, J mm. long ostiola 
projecting, Asci cylindrical, 80—90 x 8—9, with abundant par¬ 
aphyses, Sporidia filiform, yellowish—hyaline nearly straight, 
multinucleate (becoming multiseptate) ?, 75—80 x 2—2J. Dis¬ 
tinguished from O. pophyrogonus by its shorter, broader asci and 
sporidia and smaller perithecia. 
Botryosph^eria minor E. & E.—On Sesbania, Louisiana. 
Langlois 1403 (partly) Perithecia minute (150—170 micr), white 
inside, mostly in small erumpent groups of 2—6 joined in an im¬ 
perfectly developed stroma. Asci 75 x 20 micr. Sporidia crowded 
biseriate, subelliptical (narrower at the ends), 14—16 x 6—7, 
yellowish-hyaline. Differs from the larger forms included under 
Botryosphaeria (Melogramma fuliginosum), in its smaller size. 
Physalospora Sesbania E. & E.—On Sesbania macrocarpa. 
St. Martinsville, La. June 1888. Langlois, 1403 (partly). Per¬ 
ithecia scattered, 150—200 micr. diam. of rather coarse cellular 
structure, partly erumpent, papillate. Asci clavate-cylindrical
