This is a common and distinctive species which in some respects 
closely resembles P. ۸۶۸۱ Hansen and P. australis Speg. It may be 
distinguished from the former by somewhat larger spores, hyaline 
apicula and longer convoluted gelatinous appendages, and from the 
latter by having the spores in one series and by the apicula. 
The principal variation observed in the comparison of speci- 
mens from different localities, pertains to the hairiness of the peri- 
thecia and the characteristics of the gelatinous appendages. The 
Texas specimens had almost smooth perithecia, and those on horse 
dung were completely sunken with only the beak projecting. In 
all other respects the specimens did not differ from the others. . 
The convolutions of the gelatinous appendages are not always 
visible, owing to the immaturity of the spores. The best way to 
distinguish them is to examine the specimens at the time that the 
spores are being erupted from the asci. As the asci enlarge the 
appendages enlarge also, and the cross striations become more 
readily seen. They can, however, be distinguished in a nearly 
mature ascus before enlargement begins.
