KARSCHIA IMPRESSA E. & E. 
On living stems of Symmphoricarpus,San Juan Mountains, Colo- 
rado, July, 1897. (Bethel, no. 356.) 
Ascomata superficial, gregarious, flat, thin, black, round, about

ical indentations, or papillose ; asci oblong, sessile, 40-45 X 8-10 #; 
paraphyses more or less thickened and bent at the tips, sometimes 
sparingly branched; sporidia ovate-oblong, uniseptate, the septum 
mostly nearer one end, not constricted, yellowish, 8-105 yp. 
Near K. patinelloides (S. & R.). 
AGYRIELLA Ell. & Everhart. n. gen. 
Differs from Agyrium in its linear many-celled sporidia. 
AGYRIELLA BETHELI E. & E, 
(On dead stems of Aigelovia, mountains of Colorado, July, 
1897. (Bethel, no. 3402.) 
Ascoma orbicular, convex-discoid, carnose-gelatinous, smoky- 
‘gray, lighter inside and around the margin, 4-34 mm. diam., the 
entire under surface attached to the matrix; asci cylindrical, ses- 
sile, 120-I150X10-12 #; paraphyses filiform, 2 » thick, sparingly 
branched above but not thickened at the tips; sporidia linear, 
50-60 » long, made up of a series of globose or elliptical cells 
about 4 # diam. or 5-6X 314-4 yp, loosely attached to each other 
and easily separating even while yet in the asci. 
HYPHOMYCETES. 
OosPORA HETEROSPORA E. & E. 
Parasitic on Xylaria polymorpha, Missouri. (Demetrio, no. 
402.) 
Effused, thin, white. Sterile hyphae obscure or wanting; 
conidia oblong-cylindrical, obtuse, hyaline, 5-7X114-2 p, briefly 
concatenate, arising from a larger* globose or short-elliptical, — 
6-8 5-6 ys, basal cell, without any distinct fertile hyphae, unless 
the large basal cells are to be considered as hyphae. 
Differs from O. hyalinula Sacc. in the absence of any true fer- 
tile hyphae. a
