nestling in the inner bark, black, the ostiola scarcely exerted ; asci cla- 

 vate, biunt, .002 to .0024 in. long; spores collected in the upper part of 

 the ascus, allantoid, .0006 to .0007 in. long, .00016 broad. 



Dead branches of Coriius paniculata. Albany. Apr. 



I have distinguished this species from others growing on Cornus, 

 because of its different habit and larger spores. 



Valsa Friesii, FcTcL 

 Dead bark of Abies halsamea. Adirondack mountains. June. 



Valsa opulifoliae, n. sp. 



Pustules subcortical 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 .0012 to .0016 in. long, .00025 

 to .0003 broad ; spores allantoid, crowded above, uniseriate below, .0004 

 to .0005 in. long, .00008 to .0001 broad. 



Dead branches of iSpircea 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. colliculus Wormsk. 



Valsa leucostomoides, n. 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, .0016 to .002 in. long, .00035 ^'^ .0004 broad ; spores 

 crowded, allantoid, colorless, .0005 to .00065 i^- lo'^S? .00016 to .0002 

 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. 



Diatrypella Frostii, Pk. 



Dead stems of wild hazel-nut, Corylus Americana. West Albany 

 Nov. 



Diaporthe Wibbei, Nits. 



Dead branches of sweet gale, Myrica Gale. Adirondack mountains. 

 June. 



The species is placed in the section Tetrastaga, but in our specimens 

 there is no circumscribing black Ime. The spores are a little broader 

 than the dimensions given in the description, being .0002 to .00025 m 

 broad, and they sometimes terminate in a slight bristle-like point. In 

 other respects the specimens agree well with the specific characters.
