20. Sphzronema stellatum, x. sp.—On dead stems of Ilex 
glabra, May. Perithecia cespitose, ovate-conic, acute, apices sub- 
- rufous. Spores elongated, arcuate or the extremities curved in 
opposite directions, .0015-002' long, with a row of nuclei. Re- 
sembles S. cespitosum, 2%, but the elongated spores attenuated to 
a point at each end are very different. 
21. Sphzronema nigripes, ». sy.—On bark of dead Acer rubrum 
with Stilbospora ovata, Pers., October. Erumpent. Perithecia 
small, piercing the epidermis with a pale, slender, uneven, subulate 
beak, about 5';’ long.. Terminal globule hyaline minute. Spores 
oblong, obtuse with 1-2 globose nuclei, nearly hyaline, 0006-0008’ 
long. The base of the beak or ostiolum in all the specimens was 
blackened by the Stilbospora spores. : 
22. Spheronema Clethrincola, x. sy.—On dead Clethra alnifolia, 
July. Perithecia erumpent, scattered, obtuse-conic or at length 
cylindric with an enlarged base. Globule white, becoming subrufous. 
Spores oblong, hyaline, minute, not over .0002’ Jong. Not to be 
confounded with S. Magnolix, Pk., or S. minutissimum, P%., to both 
of which it bears some resemblance. 
23. Sphzronema rufum, n. sp.—On the smooth eut surface of a 
trunk of dead Magnolia glauca, Perithecia superficial, subulate, 
mirute, about $” high, rufous, paler above, globule hyaline. Spores 
minute, nearly globose. Sporophores tufted, straight, about .001’ 
long. 
DA. Sporidesmium rude, x. sp.—On living leaves of Magnolia 
glauca, October. Punctiform, crowded or scattered on brown 
spots on the upper surface of the leaves. Spores briefly pedicellate, 
brownish, varying greatly in size, oblong subcylindric, 1-7 septate 
and mostly slightly constricted at the septa, each division contain- 
ing two or more nuclei and some of them divided by a longitudinal 
septum. Mycotheca Universalis, No, 475. oe of 
25. Stilbum atrocephalum, x. sy.—On dead Kalmia latifolia, Oc- 
tober. Scattered or cespitose, stems pale, about one line high, simple 
or branched, head black, ovate or subrotund. Spores yellowish, tusi- 
form-lanceolate multiseptate .001/—0015’ long, almost exactly like 
those_of Spheronema hispidulum. 
26. Peziza (Dasc.) rhaphidospora, 7. sp.—On an old pine stump, 
October—December. Gregarious, sessile, m'nute, subconfluent, 
with white, tomentose—plane or slightly convex—asci linear- 
clavate with their apices either acute or obtuse. ‘ Paraphyses simple 
straight, rather abruptly thickened above. Sporidia tiliform, as long 
as the asci, with a row of nuclei. 
27. Peziza (Mollisia) mycogena, ». sp.—On old Polyporus 
igniarius buried in the leaves, March. Scattered, minute, fleshy, 
at length concave with an obtuse margin, pale with a greenish 
tinge. Sporidia uniseriate, elliptic or oblong elliptic, binucleate or 
with the endochrome divided so as to appear uniseptate, .0003'— 
00035’ long. The Polyporus on which this fungus grew was still 
nearly sound, its tough leathery substance having enabled it to 
resist the decomposing influences of time while the prostrate trunk 
of Oak, on which apparently it grew, had entirely decayed.
