Perithecia gregarious, superficial, convex-flattened, 1/—14 mm. in 
diameter, not polished, ostiolum papilliform, minute; asci (in the 
specimens examined) not seen; sporidia oblong-elliptical, brown, 
subacute, 20-30 X 10-12», some of them with a paler streak 
across the middle but not truly septate. 
Differs from A. sublimata Dur. & Mont. in its much smaller 
thinner perithecia, and from R. hemispherica Sacc. & Paol. and 
R. amblistoma Berl. & Sacc. in its much smaller spores. Peri- 
thecia almost as in Microthyrium. 
CERATOSTOMA BIPARASITICUM E. & E. 
On the stipe of /saria farinosa (Dicks.) Fr. Ohio (Lloyd). 
Perithecia ovate, 80-100 » in diameter, enveloped in a white 
mucedinous subiculum of loosely interwoven hyaline threads 
about 3 thick, enveloping the lower part of the /saria stipe, and 
bearing subglobose hyaline conidia 2X1% w; asci clavate-lan- 
ceolate, p. sp. 20X64, short-stipitate (paraphysate?); sporidia 
fasciculate, 8 in an ascus, oblong-cylindrical, olivaceous, 6-2 X 1% p. 
The beak of the perithecium is of a grayish-brown, of fibrous 
structure and about 1 mm. long X 35-40 » thick. 
TEICHOSPORA NEPETAE E. & E. 
On dead stems of Nepeta Catana, Granton, Ontario, Canada, 
August, 1895. (J. Dearness, no. 2351.) 
Peritheciascattered, superficial, depressed,220-—250, indiameter, 
collapsing; ostiolum papilliform, distinct; asci clavate-cylindrical , 
nearly sessile, gradually narrowed downward, 70-80 X 12-15 »; 
paraphyses linear, stout, 2-2%4 » thick ; sporidia biseriate, cla- 
vate-oblong, slightly curved, 5-7-(mostly 6-)septate, sometimes 
strongly constricted in the middle, 20-22 X 6-7 » (exceptionally 
reaching 25 X 10), yellow-brown, one or two cells divided by a 
longitudinal septum. 
Closely allied to Zeichospora vitalbae De Not. but that (sec. 
Berlese) has perithecia 300-350 in diameter, and asci cylindri- 
cal, 120-130 11-13. T. clavispoa E. & E. has rather larger 
(250-300) perithecia, not collapsing, and longer 8—10-septate 
sporidia. 
CucURBITARIA ASTRAGALI E, & E. 
On dead stems of Astragalus sp., Rooks county, Kansas. 
August, 1895. (E. Bartholomew, no. 1894.)
