Dead branches of basswood, Zilia Americana. Argusville. 
July. . 
This species approaches DP. furfuracea in its pulverulent 
stroma, but it differs in its prominent disk, which renders the 
affected branches rough to the touch, and in its smaller quadri- 
nucleate crowded or biseriate spores. From D. velata it is easily 
separated by the entire absence of any black circumscribing line 
or blackened surtace. It evidently belongs to the subgenus 
Chorostate, but the clusters of perithecia are so numerous and’ 
so closely and almost confluently placed that they form an almost 
continuous stratum which surrounds the branch and extends long 
distances under the epidermis.

In the typical form the disk is described as “sordid gray.’ In 
our specimens, both it and the stroma are yellowish green and 
pulverulent. On the smaller branches the disk is smaller and the 
ostiola are less prominent than on the larger ones. When the 
epidermis is torn away the perithecia adhere to it. The young 
spores are colorless and subacute at each end. The mature ones 
are colorled; obtuse and constricted at the septum. 
The conidia ooze out and form orbicular black patches one to 
two lines broad. These are very conspicuous by reason of the con- 
trast between their color and the white color of the matrix.

LEPTOSPHZRIA ASPARAGI, N. sp. 
Perithecia broadly conical, .01 to .014 inch broad, at first covered 
by the pierced epidermis, then naked, black; asci clavate or cylin- 
drical, short pedicellate, .003 to .004 inch long, .00045 to .0006 
broad ; spores oblong or subfusiform, crowded, .0008 to .0012 inch 
long, .0003 broad, at first colorless and triseptate, then slightly 
colored and five-septate, constricted at the septa.
