REPORT OF THE STATE BOTANIST. 103 
nestling in the inner bark, black, the ostiola scarcely exerted ; asci cla- 
vate, blunt, .oo2 to .0024 in. long; spores collected in the upper part of 
the ascus, allantoid, .0006 to .0007 in. long, .00016 broad. 
Dead branches of Cornus paniculata. Albany. Apr. 
I have distinguished this species from others growing on Cornus, 
because of its different habit and larger spores. 
Valsa Friesii, ck. 
Dead bark of Abies balsamea. Adirondack mountains. June. 
Valsa opulifoliz, 2. sp. 
Pustules subconical or subhemispherical, erumpent ; perithecia five to 
twenty in a pustule, nestling in the inner bark, crowded, often angular 
from mutual pressure, ostiola crowded, black, obliterating the grayish 
disk ; asci subclavate, the sporiferous part .cor2 to .oo16 in. long, .00025 
to .0003 broad ; spores allantoid, crowded above, uniseriate below, .ooo4 
to .0005 in. long, .00008 to .ooor broad. 
Dead branches of Spirea opulifolia. West Albany. Apr. 
The species is apparently related to V. pustulata Aw., but the crowded 
ostiola are central on the disk. When the epidermis is torn away the 
pustules appear much like those of V. colluewlus Wormsk. 
Valsa leucostomoides, x. sp. 
Pustules numerous, minute, covered by the epidermis which is pierced 
by the orbicular white or grayish disk; perithecia two to six or more in 
a pustule, the ostiola punctiform, black, dotting the disk ; asci clavate or 
subfusiform, .oo16 to .ooz in. long, .00035 to .coo4 broad ; spores 
crowded, allantoid, colorless, .ooo5 to .00065 in. long, .oc016 to .coo2 
broad. 
Dead branches of sugar maple, Acer saccharinum. Helderberg moun- 
tains. May. 
The very small size of the pustules and the minute white pulverulent 
disk give to this species an external appearance resembling that 
of V. leucostoma Fr., but there is no circumscribing black line and 
the species is apparently quite distinct and easily known by this 
character.

June. ; 
The species is placed in the section Tetrastaga, but in our specimens 
there is no circumscribing black line. The spores are a little broader 
than the dimensions given in the description, being .o002 to .o0025 in 
broad, and they sometimes terminate in a slight bristle-like point. In 
other respects the specimens agree well with the specific characters.
