Perithecia erumpent-superficial, gregarious, depressed-globose, 
Yy to'% mm. diam., thin walled and rather fragile, with an ob- 
scure or papilliform ostiolum; asci clavate-cylindrical, 75-85 8- 
10”, paraphysate, 8-spored; sporidia overlapping-uniseriate, or 
subbiseriate, fusoid-navicular, 3—4-nucleate, hy aline, constricted- 
uniseptate in the middle, 15-20X 314-4». 
Allied to MZ, éoreale E. & E. and, like that species, having peri- 
thecia quite variable in size, but distinguished by its differently 
shaped and narrower sporidia. 
TEICHOSPORA OPUNTIAE E. & E. 
On dead stems of Opuntia arborescens, Pueblo, Colo., July, 
1897. (Bethel, no. 3299.) 
Perithecia superficial, scattered or gregarious, ovate, small 
(14 mm. or a little over), minutely roughened, except the papilli- 
form or conic-papilliform smooth, black ostiolum ; asci cylindrical, 
short-stipitate, 8-spored, 75-80X9-10 »; sporidia uniseriate, 
obovate-elliptical, 3-septate, scarcely constricted unless at the mid- 
dle septum, one or two of the cells divided by a longitudinal sep- 
tum, brown, 12-14X5 %4-6 p. 
The perithecia are about the same as in Cucurbitaria minima 
E. & E. but scattered, and the sporidia are smaller and quite con- 
stantly only 3-septate. 
TEICHOSPORA INFUSCANS E. & E. 
On an old cottonwood log, Rooks County, Kansas, August, 
1897. (Bartholomew, no. 2422.) 
. Perithecia gregarious in elongated groups, blackening the sur- 
face of the wood, erumpent-superficial, subhemispherical, collaps- 
ing to cup-shape, 110-200 » diam., with a distinct papilliform 
ostiolum ; asci clavate-cylindrical, short-stipitate, paraphysate ; spo- 
ridia biseriate, narrow, oblong-elliptical, very slightly curved, a 
little narrower below, 3-5-(exceptionally 6-7) septate, scarcely or 
only slightly constricted, with a longitudinal septum running 
through one or more of the cells, pale yellowish brown, 18-22 
6-8 p. 
Differs from 7: pygmaca E. & E. in its gregarious habit and 
collapsed perithecia. :
