On rotten pine. Newfield, N. J., September 1883. 
Rhinotrichum sulfureum. — Forming a thin, sulphur-colored 
(nearly white at first) stratum on the surface of the matrix. Prostrate 
hyphae branched and septate, fertile hyph^ erect, simple, 4-6-sep- 
tate, 200-250/^ high by 7-8/^ thick, gradually attenuated above and 
bearing the elliptical, 11-15x9-10/* conidia on little tubercular, 
lateral processes. 
On rotten wood. Decorah, Iowa, October, 1882, E.W. Hohvay. 
Stilbospora fenestrata. — Stroma subcuticular and imper- 
fectly developed; spores elliptical, fenestrate, brown, 35-40x15-20/* 
on strong basidia, and, by their growth, elev^ating the cuticle in a 
pustuliform manner and finally rupturing it and oozing out so as to 
form little black patphes on the surface. 
On dead twigs oi C/ethra alm/olia Newfield, N, J., throughout the 
year. 
NiDULARiA RUBELLA. — Pcridia irregularly globose, 1-2"^"** in dia- 
meter, often confluent, two or three together, dirty white, of a loose, 
thin texture and soon disappearing; sporangia of a dull, dark red- 
dish color, orbicular or sub-elongated, about ,^3^^' ^^ diameter, not 
umbilicate, under the lens the surface appearing slightly uneven, bui 
smooth and shining as if varnished. 
After the disappearance of the peridium the mass of sporangia 
becomes flattened out and remains attached to the surface of the 
wood. 
Nearly allied to N. deniidata, Fr., from which it differs in the 
color of its sporangia. 
On decaying pine. Newfield, N. J,; autumn. 
Peziza (Mollisia) glenospora. — Sessile, orbicular, .25-5'^'°' ^^ 
diameter, dull white, becoming darker; substance of the cup coarsely 
cellular, but fringed above with a row of erect, sub-cylindrical, con- 
tinuous, hair-like cells, 8-10x2/^, rather narrower below, and their 
apices obtuse. (This structure is only visible wath a considerable 
magnifying power, the margin with a pocket lens being scarcely visi- 
ble.) Asci clavate-cylindrical, 75-80x9-10//; paraphyses curved and 
swollen at their tips; sporidia elliptical, or rather more acute at one 
end, with a single large nucleus, 12-15x7-8//. 
The young sporidia are filled with numerous globose nuclei^ but 
these soon unite into one and often cause the sporidia lying in the 
asci to appear globose, since the two ends, because of the thin epis- 
pore, are so transparent as to be almost invisible. 
On rotten Magnolia. Newfield, N. J., November, 1883. 
Untenable Names of Carices.—A number of old and doubtful 
names was resuscitated by Olney and made to replace familiar 
ones in his published fasciculi. These names have in some instances 
been adopted in local floras, and should be arrested before coming 
into more general use. The doing away with generally adopted 
names results at best in more or less confusion, and it should not be 
tolerated when any doubt exists as to the application of the revived 
names. The following names introduced by Mr. Olney are uncertam 
as to application, and deserve not to be regarded as synonyms even;
