VALSA MACROCARPA E. & E. 
On dead limbs of Quercus macrocarpa, Rooks Co., Kansas, 
Ap. 1897. (Bartholomew, no. 2393.) 
Perithecia ovate-globose, about % mm. diam., 15-30 in a 
cortical stroma formed from the unchanged substance of the bark, | 
closely packed in a single layer, subangular from mutual pressure; 
ostiola erumpent mostly around the margin of a light-brown disk, 
black, rounded at the tips, becoming flattened and umbilicate ; 
asci clavate-cylindrical, p. sp. 23-30X5-6u; sporidia biseriate, 
allantoid, rather strongly curved, hyaline, 6-7X11{-1 4p. 
The disk is at first convex, but finally plane, rising but little 
above the epidermis which it perforates and raises into slight 
pustules. 
EuTyPELia TILIAE E. &. E. 
In bark of dead 7zia Americana, Canada (Macoun). 
Stroma cortical, formed of the unaltered substance of the bark, 
not circumscribed; perithecia circinate, ovate-globose, 14 mm. 
diam., buried in the inner bark, necks converging and terminating in 
an erumpent fascicle of ovate-conical quadrisulcate ostiola; asci 
clavate-cylindrical, 40% long (including the slender stipe), p. sp. 
22-25 X 3, paraphysate, 8-spored; sporidia biserate above, allan- 
toid, hyaline, 4-4% XIp. 
The tufts of ostiola are %-34 mm. across, the tips slightly 
spreading. 
VALSARIA XANTHOXYLI E. &, E. 
On Xanthoxylum Clava-Herculis, St. Martinville, La., March, | 
1897. (Rev. A. B. Langlois, no. 2500.) 
Stromata pulvinate, 2-6 mm. diam. consisting mainly of a 
brownish-black subcarbonaceous crust of rather loose texture, 
covering the small, ovate-oblong, IX%—l%4y, membranous, 
perithecia which are seated in a closely packed group on the un- 
altered surface of the wood; ostiola tuberculiform-conical, at- 
length broadly perforated or umbilicate; asci cylindrical, p. sp., 
75-80 8-10, with abundant paraphyses; sporidia uniseriate, 
elliptical, uniseptate and mostly constricted, brown, 12-14X6-7p- 
CURREYA RIMOSA E, & a 
On dry hard wood of Arctostaphylus tomentosa (Manzanita), 
San Diego, Calif., July, 1896. (Bethel, no. 87.) 
Stroma erumpent, -superficial, tuberculo-hemispherical or | 
oftener hysteriiform-elongated, 1-2 mm. long, % mm. broad, 
flattened above, surface minutely roughened, black or, when pre-. 3
