staining with its yellow mycelium the decaying wood beneath, at 
length disappearing in the spaces between the perithecia. Not to 
be confounded with Sphaeria subiculata, Schw., which is quite a 
different thing. 
43. Sphaeria (Denudatae) longispora, ». s¢.—Sparsa, ovato- 
- conica, ostiolis minutis, leviter prominentibus, ascis cylindraceis, 
.005'—006' X .0004’-.0005’; sporidiis subhyalinis, linearibus, ascos 
subaeqantibus, utrinque acuminatis—On decaying wood of Kal- | 
mia latifolia lying on the ground. July, 1874. 
Perithecia small, dull, black, not polished, ovate or ovate-conic ; 
ostiolum slightly prominent, minute; asci cylindric; sporidia nearly 
colorless, linear, nearly as long as the asci, narrowed to a slender 
point at each end, with a row of nuclei. 
44. Sphaeria (Denudatae) vetusta, 7. s9—Gregaria, superfici- 
alis, cylindrico-conica; ostiolis papillaeformibus; ascis late cylin- 
draceis, basi abrupte contractis; sporidiis monostichis, ellipticis, 
primo uniseptatis, mox fenestratis.—On a dead place in the trunk 
of a Maple tree where the bark had been rubbed off. Nov. 1874. 
Gregarious, superficial, of medium size; perethecia thin, elonga- 
ted conic, not polished, dull black, ostiolum depressed hemispheric, 
black and shining, with a large opening; asci broad, cylindric, obtuse, 
abruptly narrowed at base, .005’ X .001’; sporidia uniseriate, obtusely 
and broadly elliptical, nearly colorless, uniseptate and more or less 
constricted at the septum when young, at length brown and fenes- 
trate, .c009’—.001’ X.0005’._ The mature sporidia are not constricted. 
45. Sphaeria inflata, x. s6.—Sparsa, parva, adnata, nigra, im- 
polita, subhemispherica demum superne collapsa; ostiolo haud 
prominente, irregulariter pertuso ; ascis late cylindraceis, .o04’X .oot’, 
subsessilibus, sporidia octo oblongo-elliptica foventibus.—On the dry 
exposed surface of Red Oak railroad ties, Jan. 
Scattered or subgregarious, closely adnate, black, rough subhem- 
ispheric or depressed conic; ostiola not prominent, with a rather 
large opening; asci broad cylindric, subsessile; sporidia oblong- 
elliptic, crowded, dotted with transparent nuclei; hyaline, triseptate _ 
and constricted at the septa, which are more readily seen when — 
treated with tincture of Iodine.—The surface of the perithecia and 
the wood adjacent is generally overspread with loose, creeping, 
sparingly septate threads, sending up here and there erect, closely 
septate branches. 
Sphaeronema nigripes, Vol. VI., No. 21, is probably not dis- 
tinct from .S. acerrzmum, Pk: All the foregoing, except No. 40, were 
collected in the vicinity of Newfield, New Jersey. : 
§ r45. A new Fungus from Pennsylvania.—Pestalozzia Ste- 
vensonii, Peck.—Pustules small, hysteriiform or pezizoid, erumpent, 
closely surrounded by the ruptured epidermis, black; spores fusi- 
form, triseptate, .0007~.0008 inch long, (colored part .0005—.0006) 
the terminal cells hyaline, the two central ones colored, terminal 
bristles three or four, widely divergent; sporophores about equal in 
length to the spores, easily separating.
