.Diatrype pustulans, E. & E.—On dead stems of Arundinaria. 
St. Martinsville, La. Langlois 1215 (partly). Stromata flattened, 
formed of the scarcely altered substance of the matrix, covered 
by the cuticle which is blackened and raised in a pustuliform 
manner and finally pierced by the slightly projecting papilliform 
ostiola. The separate stromata are \—| cm. across but are more 
or less confluent with each other for 2—4 cm. or more in extent, 
the surface of the culm being continuously blackened and the 
entire area bounded by a black circumscribing line. Perithecia 
membranaceo-coriaceous, subglobose or a little flattened, of me¬ 
dium size, 8—12 in a stroma. Asci slender, 75 — 85 x 6—7, sub- 
sessile, with distinct filiform paraphyses. Sporidia 1-seriate, 
oblong, 1-septate and constricted, slightly narrowed at the ends, 
straight, brown, 10—12 x 3. This is preceded or accompanied 
by a Coiriothyrium with numerous small, immersed-perithecia 
and small (2 micr.) brown sporules which ooze out and stain the 
surface of the matrix with an olivaceous, pulverulent coat. 
*Diatrypella decipiens, E. & E.—On bark of Umbellularia 
Californiea. Sent from Coos Co., Oregon, in Feb. 1884, by our 
esteemed friend, the late Wm. S. Carpenter. .Stroma ernmpent, 
black (lighter colored at first), orbicular, or oblong, 2—6 mm. 
Across, pulvinate, convex or, in the larger specimens, almost plane, 
whitish inside, with a black circumscribing line around the base. 
Ostiola slightly prominent, quadrisulcate, situated in a slight de¬ 
pression. Perithecia monostichous, oblong-ovate about J mm. 
long, contracted abruptly into a short neck above. Asci (p. sp.) 
50—70 x 6—7, polysporous. Sporidia yellowish, allantoid, mod¬ 
erately curved, 3i-—4| (or exceptionally 5 micr. long) and less 
than 1 micr. thick. This can not be distinguished by its external 
characters from Diatrype bidlata , (Hoff.) but internally it is very 
different 
Gnomonia tenella, E. & E.—On fallen and decaying leaves of 
Acer rubrum, Newficld, N. J., June, 1888. Perithecia amphi- 
genous, scattered, mostly on the lamina of the leaf and not con¬ 
fined to the veinlets, depressed-globose, small (J—| mm.) covered 
by the cuticle which is raised above it. Ostiolum black, straight, 
bristle-like, about 1 mm. long. Asci fusoid, 50—70 x 6—7. 
Sporidia fasciculate, narrow cylindrical, nucleate, 16—22 x 1J— 2 
with a long slender pointed, hair-like appendage at each end 15— 20 
micr. long. Specimens on Rubus fruticosus in Kunze’s Fungi Set 
113, referred to G. setacea Pers. are much like this if not the 
same. The apical appendages on the sporidia are coiled in the
