PLEURAGE 87 
agglutinated hairs, which are prominent around the base of the 
beak and decrease to mere scattered papillae downward; uni- 
formly scattered among the latter are long filiform flexuous sep- 
tate brown hairs, which gradually become transformed below into 
the rhizoids, which ramify through the substratum. 
Asci 16-spored, cylindrical-clavate, contracted and narrowly 
rounded above and contracted below into a short stout stipe, 
34-40 M X 230-240 زم‎ very evanescent: paraphyses exceedingly 
ventricose, agglutinated and not at all mixed with the asci, often 
very indistinct 3 appear more like a tissue lining the perithecium 
than like filamen 
Spores Ge ellipsoid, broadly rounded at both ends, 
18-20 4 x 27-342; primary appendages entirely wanting, the 
apex of the spore tipped with two awl-shaped parallel or slightly 
divergent rather firm gelatinous appendages, which in the ascus 
are curved so as to appear as one; lower end of the spore bearing 
two similar appendages but much more delicate curved and vari- 
ously twisted appendages. (PI. r7. f. 1-3.) 
Distinctive characters: Hairs of RT and absence of pri- 
mary appendages. 
Cultivated specimens: On cow dung, Family, Mont., Sept. 
1900. 
27. Pleurage Dakotensis sp. nov. 
Perithecia scattered, superficial or with the base slightly 
sunken, pyriform with papilliform to conical curved beak, abou 
375 x 6004, thin, membranaceous, fuscous, transparent and 
covered, especially above, by tufts of agglutinated obliquely- 
septate fuscous hairs 
‚Sci 32-spored, clavate, broadly rounded above and contracted 
below into a short stipitate base, rather persistent, 30-40 4 x 
175-220 2: paraphyses slightly ventricose, septate, longer than 
the asci, but not mixed with them. 
Spores in 2-4 series, ellipsoid to slightly ovate, rounded at 
the ends, 12-15 » x 18-23 رم‎ ranging from hyaline when young 
through olivaceous to dark brown and opaque : primary append- 
age short, cylindrical, straight and fugacious ; secondary append- 
ages tipping the primary pa the apex of the spore, long, lash-like 
and very fugacious. (77. 7. f. 17-19.) 
Distinctive characters : Many- -spored ascus and agglutinated 
hairs of the perithecium. 
Cultivated specimens: On rabbit dung, Ft. Lee, N. J., Jan. 
1900; Cow dung, Brookings, S. D., Nov. 1899 (Carter); cow 
dung, Austin, Texas, Jan. 1900 (Long); rabbit dung, Auburn,
