74 TWENTY-EIGHTH REPORT ON THE STATE MUSEUM. 
spores crowded or biseriate, simple or obscurely uniseptate, 
oblong, narrower toward one end, hyaline, with a minute 
bristle at each end, .0003’ long. 
Dead stems of raspberry, Rubus strigosus. Albany. 
May. 
The septum is not always clearly visible. When present 
it divides the spore into two unequal parts. 
The appendages are so small as to be easily overlooked. 
The bark is generally stellately wars over the pustules. 
VALSA MUCRONATA 2. SD. 
Perithecia four to eight, rather large, nestling in the inner 
bark, surrounded by a black line; ostiola separately erum- 
pent, not collected in a disk, slightly prominent, black, 
sometimes circumscribed by an obscure black line; asci 
lanceolate; spores crowded, large, uniseptate, colorless, 
.0016’—.0021’ long, generally with a short appendage or 
mucro at each end. . 
Dead willow branches. Sandlake. September. (Plate 2, 
figs. 10-13.) 
This species is very distinct both in its separately erum- 
pent ostiola and in its spores. The appendages are so short 
as to resemble a little mucro, whence the specific name. It 
is an aberrant species, the ostiola not agreeing well with the 
generic character. 
VALSA ACERINA 7. Sp. 
Pustules small, erumpent; perithecia sunk in the wood, 
covered above by a thin blackish crust and surrounded by 
a black line; ostiola prominent, elongated-conical or cylin- 
drical ; spores oblong or subelliptical, subacute, colorless, 
.0005’ long, the endochrome one to three times divided. 
Dead branches of Acer spicatum. Indian Lake. July. 
VALSA SUFFUSA F7. 
Dead alder branches. Buffalo. Clinton. 
VALSA FEMORALIS 72. Sp. 
Pustules small; perithecia few, nestling in the inner 
bark ; ostiola few, black, short, erumpent through small 
and mostly transverse chinks, crowded or scattered ; asci
