114 NORTH AMERICAN SORDARIACEAE 
stricted and easily separable, brown and opaque when mature ; hya- 
line covering rather narrow. (FPL 26. f. 7-9. 
Distinctive character : Long hairy beak of perithecium. 
Cultivated specimens : On cow dung, Biloxi, Miss., Sept. 1899 
(Tracy) ; cow dung, Tucson, Ariz., June 1900 (Tyler). 
There is considerable difference in spore measurements in the 
specimens from Mississippi and Arizona. In the former they 
measure 26-30 بر‎ in length while in the latter they are 28-40 م‎ 
long. There is no other difference. 
The species is one of the most difficult of the genus to secure 
measurements of the asci. Even after treatment with iodized po- 
tassium iodide for a considerable period before rupturing the peri- 
thecium, many of the asci elongate in apparently a normal manner. 
This may occur even in the olive green state of the spores, and 
when the epiplasm of the ascus is deeply stained by the iodine. 
11. Sporormia Dakotensis sp. nov. 
Perithecia scattered or aggregated in small clusters, sunken, 
globular with a long projecting narrowly cylindrical curved straight 
or variously contorted bare black beak, 350-4502 x 700-800 f, 
thin membranaceous, finally becoming black and opaque. 
Asci 8-spored, clavate, rounded above and contracted below ` 
into a long slender stipe, 8-11 u x 90-1102: paraphyses filiform, 
abundant, septate, longer than the asci and mixed with them. 
Spores in 2 or 3 series, cylindrical, straight or curved, rounded 
at ihe e nds, 3-4/4 x 22-24 ہم‎ 4-spored, deeply constricted and 
easily separable, hyaline covering narrow and often indistinct. (ZZ 
15. f. 7-9. 
E EH characters: Long slender beak and small spores. 
Cultivated specimens: On horse dung, Brookings, S. D., 
Nov. 1899 (Carter); cow dung, Biloxi, Miss., Sept. 1899 
(Tracy); Great Falls, Mont., Aug. 1900 (Griffiths & Lange). 
12. Sporormia Americana sp. nov. 
Perithecia scattered, sunken, with short black shining papilli- 
form beak projecting onto the surface of the substratum, 175 سر‎ 
225 م‎ in diameter, globular to ovate, thin membranaceous to coria- 
ceous, black and shining when removed from the substratum to 
which it is firmly attached. 
Asci 8-spored, cylindrical-clavate, broadly rounded above and 
contracted below into a short stipitate base, 27-32 x x 160-210:
