142 THIRTY-FIFTH REPORT ON THE STATE MUSEUM. 
Spots small, angular, reddish-brown, a little paler on the lower 
surface; flocci hypophyllous, tufted, short, slightly colored ; 
spores fusiform or oblong-cylindrical, colorless, -0005—-0014 
long. 
Living leaves of witch-hazel, Hamamelis Virginica. Sand- 
lake. July. 
Though the spots are distinct enough, the fungus is so minute 
that it is scarcely visible to the naked eye. 
RAMULARIA AQUATILIS, 2. sp. 
Spots small, pale; flocci epiphyllous, tufted, very ‘slender, short, 
flexuous, white, -0003’—-0006' long; spores subfiliform, nar- 
rowed toward one end, sometimes three to four-nucleate, color- 
less, -0008’—-0012 long, -0001’—-00012' broad. 
Living leaves of pond-weed, Potamoyeton lonchites. Albany. 
September. 
The tufts are numerous and very small and white. When 
magnified they have a stellate appearance, the spores diverging 
like rays from the central mass of flocci. 
ASTEROPHORA PEziIzm, Cd. 
Hymenium of Peziza hemispherica. Center. July. 
This fungus covers the inner surface of the Peziza with a white 
stratum of slender filaments and stellately warted spores. 
PEZIZA LETIRUBRA, Cke. 
Decaying leaves lying on damp, sandy soil. Center. Septem- 
ber. 
PxEzi1zA (MOLLISIA) SINGULARIA, 7. Sp. 
Cups minute, waxy, sessile, flattened or convex, se distinctly 
margined, seated on irregular, indefinite pallid spots, dingy-gray 
or pale amber-brown ; = cylindrico-clavate, -002'—-003' long, 
-0003'—-0004' broad; spores crowded or biseriate, colorless, ob- 
long, sometimes slightly narrowed toward one end, -0005 —- 0006’ 
long, -00016'—-0002' broad; paraphyses filiform, scarcely thick- 
ened at the apex. 
Under surface of living leaves of hispid crowfoot, Ranunculus 
hispidus. East Berne. August. 
This is one of the few species of Peziza that attack living plants. 
Sometimes the cups, or rather the receptacles, are confluent and 
irregular. Perhaps a form of Pseudopeziza Ranunculi, Fckl. 
TyMpANIS NEMOPANTHIS, n. sp. 
Receptacles minute, densely tufted, substipitate, black, at first 
sphwriiform and opening by a slight irregular chink, then with 
the disk exposed, slightly margined, concave or plane; asci
