58 NORTH AMERICAN SORDARIACEAE 
Distinctive characters: White tomentum, setae of perithecia, 
and entire absence of primary appendages. 
Cultivated specimens : On sheep and cow dung, Tucson, Ariz., 
Jan. 1900 (Tyler); cow dung, Mesilla Park, N. M., Jan. 1900 
(Wooton). 
A very characteristic species which is easily distinguished from 
P. taenioides to which it is most closely related, by the charac- 
ters given above. In age and in the presence of an excessive 
amount of moisture the white tomentum disappears and the ex- 
posed portion of the perithecium becomes black and bare, with 
the exception of the convex portion of the beak which bears the 
tufts of setae. 
3. Pleurage taenioides sp. nov. 
Perithecia scattered, half sunken, or occasionally aggregated in 
small clusters and erumpent between the fibers of the substratum, 
about.5 mm. x .75 mm., slightly olivaceous when young, but be- 
coming black, opaque and slightly coriaceous at maturity, covered 
uniformly, on all exposed portions by short straight septate 
brown hyaline-tipped fugaceous hairs, globular to pyriform with a 
long cylindrical curved or twisted beak. 
Asci 4-spored, cylindrical, broadly rounded above and con- 
tracted below into a long slender crooked stipe, persistent, 37— 
45 4 x 290-360 p: paraphyses filiform to tubular or even slightly 
ventricose below, tapering upward, septate, longer than the asci. 
Spores uniseriate, ellipsoid to oval, broadly rounded at the 
ends, ranging in color from hyaline when young through oliva- 
ceous to dark brown and opaque, 29-32 ۸ x 56-62 p: primary 
appendage reduced to a minute hyaline or often slightly colored 
apiculum at lower end of the spore, the secondary lower appendages 
gelatinous, very long, attached apically to spore and inclosing 
the minute apiculum ; easily resolved into two closely united por- 
tions which appear to lose their individuality distally, more or less 
of the length being thrown into convolutions resembling segments 
of the tapeworm ; upper appendage € smaller than the lower 
and eccentrically attached. (77. 6. 
Distinctive characters: Large REA minute apiculum and 
long convoluted appendages.
