ness of the perithecium; and two of these are recognized by 
Rehm,* P. curvula coronata and P. curvula aloides. 
The typical form of Pleurage curvula aloides has been met 
with from a single locality in the vicinity of New York City. All 
gradations of hairiness occur from small tufts scarcely larger than 
those of P. minuta to the prominent tufts represented in pl. 7.

Perithecia scattered or loosely aggregated, erumpent with 
simply the base sunken at maturity, pyriform to conical and clothed 
on all exposed portions except the black papilliform to conical 
beak with short sparingly septate crooked brown hairs, about 
400 م‎ x 500-600 u thick, coriaceous, black and opaque. 
Asci 3—8-spored, cylindrical, rounded above and contracted be- 
low into a short blunt stipitate base, evanescent, 20-24 مم‎ x 170— 
190 4: paraphyses filiform above but slightly ventricose below, 
longer than the asci and not much mixed with them. 
Spores obliquely uniseriate, ellipsoid to ovate and irregular in 
outline: 18-24 u x 30-45 :م‎ primary appendage short cylindrical 
or clavate, straight or curved, hyaline to brown ; secondary ap- 
pendages long, lash-like and attached to the extremity of the 
primary and to the apex of the spore, the upper one being the 
larger and often tinted with brown. (7. 7. f. 74-76.) 
Distinctive characters: Perithecial hairs and short primary 
appendages of the spores. 
Dry specimen: On old corn stalks, Rooks Co., Kan., July, 
1896 ( Bartholomew). 
This type was kindly loaned to me by the collector. Like 
some other species of this family the number of spores in the ascus 
appears to vary on account of abortion of one or more of the typ- 
ical number, eight. The ascus illustrated in the accompanying 
figure has but seven spores with no signs of the eighth. This is 
often the case in mature asci but in the younger ones one or 
more hyaline abortive spores may be found mixed with the olive- 
green to light brown ones. This is not due to an inequality in 
the time of maturity as is the case in some Ascomycetes.
