black; asci oblong-clavate; spores linear, curved, involved 
in mueus, slightly colored, .0011’—.0012° long. 
Dead stems of leather leaf, Cassandra calyculata. June. 
Cenangium pezizoides Pk. Cups scattered, minute, 
erumpent, sessile or attached by a narrowed base, smooth, 
black; asci oblong-clavate; spores erowded oblong-elliptical, 
.0008°—.001‘ long, often containing a single large nucleus, 
sometimes slightly curved. 
Dead stems of leather leaf, Cassandra calyculata. June. 
This was associated with C. Cassandr&, but the two 
are easily distinguished. 
Tympanis acerina Pk. Cubs subezspitose, obconic, 
erumpent, black with a distinet often flexuous margin, disk 
concave; asci oblong-cylindrical; spores oblong, colored, 
.0005°—.0008° long, containing a granular endochrome, at 
length quadrinucleate or triseptate. 
Bark of maple trees. Aug. and Sept. 
The cups often manifest a tendency to form lines or - 
grow in linear tufts. They are usually accompanied by 
Sphzeronema acerina, which is probably one condition of 
the species. Both frequently grow from the same chink in . 
the bark. 
Phacidium brunneolum Pk, Perithecia small, in- 
nate, brown or blackish-brown, with four or five rather 
broad teeth; disk dingy-withe; asci eylindrical or clavate, 
narrow; spores small, colorless, sublanceolate or oblong- 
ovate, often binucleate, .0003°—.0004° long. 
Fading leaves of Galium trifidum. Sept. 
I have seen no description of Phacidium autumnale 
Fcekl., but according to my European speeimens of that 
species, our plant is quite different. 
Triblidium morbidum Pk. Perithecia seated on 
a thin black crust, irregular, elliptical or oblong, rugose, 
black, at length widely gaping or even suborbicular, revea- 
ling the dingy-white or cinereous disk; asci narrowly lan- 
ceolate, tapering towards the base; spores filiform, .003’— 
.004° long. 
Decaying prostrate trunks of spruce. Aug. 
The general appearance of the perithecia is such as to 
suggest the idea that they are diseased or badly developed. 
They indicate that the nt is a Triblidium, but the spores 
are like those of Colpoma. 
Valsa Xanthoxyli Pk. Pustules slightly prominent, 
erumpent, with a yellowish or tawny furfuraceous disk which 
is dotted by the ostiola; perithecia two to fifteen, rarely 
single, fragile, pale, surrounded by a tawny tomentum,
