Fusicladium Alopecuri, E. & E.—On leaves of Alopecurus genicu- 
latus , Columbia, Mo., May, 1887. B. T. Galloway, No. 2G7. Tufts com¬ 
pact, grayish, thickly scattered over the partly dead tips of the leaves ; 
hyphse smoky-hyaline, continuous, subtruncate and more or less shoul¬ 
dered and toothed above but otherwise nearly straight; conidia clavate- 
oblong, olivaceous, granular, continuous or with faint indications of a 
medial septum, 20—85 x 7—10 p. Closely allied to F.fasciculatum, C. & E., 
but tufts more compact, hvphse thicker and straighter and conidia larger; 
except the habitat, however, there is no serious objection to considering 
this a mere variety of that species. 
Fusicladium ascyrinum, E. & E.—On dower bracts and pedicels of 
Ascyrum crux Andrew , Natchitoches, La., September, 1880. Langlois, 
No. 705. Hyphse mostly at the base of the bracts, appearing like patches 
of black pubescence, which consists of closely crowded fascicles of erect, 
septate threads about 75 x 4 p, nearly opaque below, subhyaline above 
and bearing at their tips the subhyaline, ovate-oblOng, 2—3-nucleate, 
16—20 x 4—6 p conidia, either singly or 2—8 standing on the tip of the 
same thread or often attached to little tooth-like lateral projections near 
the tip of the thread. Sometimes the conidia are briefly catenulate. 
Mystrosporium erectum, E & E.—On decaying stalks of Zea 
Mays , Pointe ’a la Ilache, La., December, 1886. Rev. A. B. Langlois, 
No. 862. Forms a thin, continuous, sooty black, granular-looking coat on 
the matrix and is made up of straight, erect, septate, fuscous, (subhya¬ 
line above), fertile hyphse, 35—40 p long and 3—4 p thick, each bearing an 
erect, terminal, obovate-elliptical conidium, 22—25 x 12—16 P , nearly 
opaque and indistinctly cellular. More like the conidia of a Sporidesmium 
in which this might be placed only for the distinct, well developed fertile 
hyphse. 
SPORIDES3HUM fumosum, E. & E—On dead twigs of Quercus alba, 
Newfield, N. J., November, 1887. Forming'a thin, smoky-black coating 
on the matrix which is overrun with brown branching toruloid threads 
whose free ends support the brown, cellular, subglobose, subcatenulate 
conidia 10—16 p in diameter, often at first sarcinuliform,L e. divided into 
four cells by two septa at right angles to each other. 
Cercospora leucosticta, E. & E —On leaves of Melia Azedarach, 
St. Martinsville, La., November, 1887. Rev. A. B. Langlois, 792. Spots 
small (1—2 mm.), white, scattered ; hypliee amphigenous, tufted on a 
tubercular base, yellowish-brown, continuous or faintly 1—3-septate, 
40—50 x 4—5 P , subundulate and shouldered above, with the obtuse tips 
often marked with 2 or 3 scars marking the points of attachment of the 
hyaline, obclavate, 5—10-septate, 60—80 x 3i—4i P conidia. Many of the 
spots are sterile, and on others oidy a few tufts of hyplne are seen, but 
on the fertile spots (mostly the larger ones) the tufts are thickly scat¬ 
tered over the spots, except a narrow strip around the margin. This is 
readily distinguished from the other species on Melia by the small white 
spots.
