SORDARIA 49 
Kan., July, 1899 (Bartholomew) ; cow dung, Schaghticoke, N. Y., 
Aug. 1899 (Banker); horse dung, Aberdeen, S. D., Sept. 1899 
(Towne) ; cow dung, Biloxi, Miss., Aug. 1899 (Tracy). 
Outwardly this species resembles Sporormia minima some- 
what. It appears to be quite widely distributed, but it has never 
been met with in any great quantity. Usually only a few scat- 
tered perithecia have been found in one culture. 
8. Sordaria Montanensis sp. nov. 
Perithecia scattered, sunken, 450-600 1x 750-900 p, thin. 
membranaceous, dark brown to black in color, subglobose to 
oval with a long black cylindrical projecting beak; all exposed 
portions, especially the beak, densely covered with short straight 
acuminate sparingly septate hairs of approximately equal length; 
these become gradually changed into the long flexuous rhizoids 
which cover the sunken portions of the perithecium. 
Asci 8-spored, cylindrical, rounded or truncated and perforate 
at the apex, and tapering below into a long stout stipe, quite per- 
sistent, 29-32 عام‎ 340-400 4; paraphyses filiform, septate, slightly 
longer than the asci. 
Spores obliquely uniseriate, ellipsoid, broadly rounded at the 
ends, 24-27 MX 45-51 م‎ tipped below by a broad, conspicuous, 
hyaline apiculum, and at the apex by a very much smaller incon- 
Spicuous one; the spore and its apicula surrounded by a gelati- 
nous covering which becomes very wide and conspicuous when 
mounted in water. )7 3. f. 1-3 and Pl. 19. f. r3. 
Distinctive ei d. Long cylindrical hairy beak and apicu- 
late spores. 
Cultivated specimens: On horse dung, Missoula, Mont., Jan. 
1900 (Elrod); horse and cow dung, Summit, Mont., Aug. 1900 
(Griffiths & Lange). 
` This is a very striking species which is decidedly different 
from anything else in the genus. The spore apicula show a close 
relationship to the genus Pleurage, while the hyaline envelope, 
which is very pronounced, and the apical perforation of the ascus, 
locate it without doubt in the present genus. It occurred rather 
rarely in the first cultures, but abundantly in the last. 
9. Sordaria alpina sp. nov. 
Perithecia sunken, scattered, or aggregated in small clusters, 
pyriform, thin, membranaceous, olivaceous below but black in all 
exposed portions, about .5x I mm., the black projecting long
