PLEURAGE 18 
Cultivated specimens: On cow dung, Englewood, N. J., 
Aug. 1899; cow dung, Newfield, N. J., Aug. 1899 (Ellis). 
The spores and asci of this species resemble those of P. curvula 
somewhat, but it is readily distinguished from this species by the 
external characteristics of the perithecium. Two collections of 
this species were made near Englewood during the month of 
August; but in each case the perithecia were few and scattering, 
as were also those obtained from the Newfield cultures.
