purplish under a lens; stems straw-colored, twisted, tapering up- 
wards; columella none. 
On bark and wood of Ailanthus. The peridia are sometimes very 
irregular and occasionally subsessile. The outer coat is white, thin, 
and closely adheres to the smooth, delicate internal peridium. 
3. Hypoxylon smilacicola, n. sy.— Small, black, roundish or 
elliptical, irregular when confluent, pulvinate ; perithecia subglobose; 
asci cylindrical or subclavate ; spores brown; sub-cymbiform, .0006’ 
—.0008’ in long and .0003’ wide, usually with several nuclei. 
On dead stems of Smilaz. The spores are rarely elliptical atma- 
turity, but sometimes pointed at both extremities.

Uromyces Pontederiz, Gerard.—Hypophyllous, scattered, often 
following the nerves, sori small, at first covered with the somewhat 
bullate cuticle, then irregularly ruptured, snuff-brown ; pseudo, 
spores oblong or ovate, on very short pedicels, apex with a small 
_hyaline spot, scarcely papillate. : 
On leaves of Pontederia cordata, Poughkeepsie, N. Y. 4 
Peziza griseo-rosea, Gerard.—Sessile, cups fleshy, rather thin, 
hemispherical, then expanded, externally greyish-ochre, rather 
mealy; disc pale rosy, becoming pale brownish (1—1} in. broad); 
asci cylindrical; sporidia elliptical, rough (.015—.018 X .0075 — 
-01 mm. or .0006’— .0007’  .0003’—.0004’). Paraphyses linear 
scarcely incrassated. 
On ligneous earth in woods. Poughkeepsie, N. Y. 
Helotium pullatum, Gerard.—Gregarious, dark dingy ochre when 
fresh, becoming darker and fuliginous when dry; at first clavate, 
then somewhat obconical, externally darker ; stem short, expanding 
. into the cup; dise plane, concave when dry, immarginate (1—2 
mm. broad); asci cylindrical, narrow; sporidia linear, obtuse 2—4 
nucleate, at length pseudo-septate (.018—.02  .004m.m.) yellowish. 
On stems of Vitis, in damp places. Poughkeepsie, N. Y. : 
Microspheria Van Bruntiana, Gerurd.—Amphigenous; mycelium 
dense, white, persistent ; conceptacles globose, scattered or gregani- 
ous; appendages 12—15; abvut equal in length to diameter of 
conceptacles, several times dichotomous, truncate at their apices ; 
sporangia ? Containing eight spores. 
On leaves of Sambucus Canudensis. The structure of the 
appendages is very different from that of ae other species with 
which we are acquainted. Poughkeepsie, N. Y. : 
Peziza (Humaria) Gerardi, Cooke.—Violaceous, sessile, fleshy. 
Cups hemispherical, then flattened, externally greyish-violet; disc 
dark violet (2 lines broad); asci, cylindrical (.23 mm. long); 
sporidia fusiform, with a central nucleus (.032—.035 X .008 — .009 
mm., or .0011’ X .0003’). Paraphyses filiform, clavate at the ete

shaped, margin contracted; disc slightly paler; asci cylindrical ; 
sporidia oval or elliptical, with two nuclei (.02  .01 m m. or .0006
