Dead branches of basswood, Tilia Americana. Argusville. 

 July. 



This species approaches D. furfur acea 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 surface. 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.

LEPTOSPH-2ERIA 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.
