PLEURAGE 57 
Asci 4-spored, cylindrical, broadly rounded above, and taper- 
ing below into a slender stipe, 18-21 2x 165-190 و :م‎ 
agglutinated, ventricose, longer than the asci. 
ores uniseriate, ellipsoid to subglobose, rounded above 
and broadly rounded to truncate below, 13-16 ,م 18-21 عام‎ dark 
brown in color ; primary appendage nearly equalling the spore in 
length, cylindrical, straight or slightly curved, tipped as is also 
the apex of the spore with long lash-like gelatinous secondary 
appendages of variable length. (7/7. 5. f. 7-9.) 
Distinctive characters: Dense growth of mycelium and 4- 
spored ascı. 
Cultivated specimen: On cow dung in Columbia greenhouse, 
New York City, spring and summer, 1899. 
In the old state the species resembles P. coprophila very closely 
for then the hairiness of this species and the tomentum of the 
other disappear. But even then they can be separated readily by the 
characteristics of the asci and spores. It has not been met with 
except in the one locality mentioned above, but several collections 
of it were made here. The substratum had been used as a mulch- 
ing for a species of palm and had remained in the greenhouse 
since the previous autumn. 
2. Pleurage Arizonensis sp. nov. 
Perithecia scattered or aggregated in small groups, at first 
sunken, but becoming half exposed at maturity, 400-600 مم‎ in 
diameter, membranaceous to slightly coriaceous, black and opaque, 
globular to pyriform, the exposed portion covered with a white to- 
mentum up to the short cylindrical or papilliform black and 
curved beak, the convex side of which is ornamented with several 
tufts of long brown hairs. | 
Asci 4-spored, cylindrical, slightly contracted and rounded at 
the apex, and tapering below into a long slender crooked stipe, 
38-45 p x 240-325 p: paraphyses variable, usually broadly fili- 
form, tapering upward, much longer than the asci, the outer ones 
decidedly ventricose and somewhat agglutinated. 
Spores vertically uniseriate, ellipsoid, inequilateral or slightly 
flattened on one side, broadly rounded at the ends, 21-25 مم‎ x 
45-52, ranging from hyaline when young through olivaceous 
to dark brown and opaque ; primary appendages entirely absent, 
but both upper and lower ends of the spore are tipped with long, 
lash-like, gelatinous, eccentrically attached appendages which are 
marked longitudinally with a furrow which shows them to be 
made up of two closely united filaments. (P? 6. f. 4-6.)
