IOWA DISCOMYCETES §3; 



at first globose then flattened; hynienium convex, papillate, im- 

 marginate; asci broad, elavate, attenuated below, 8-sporedr. 

 spores elliptical, smooth or very minutely roughened, hyaline, 

 about 18 by lO/u; paraphyses enlarged upwards, septate. 



On cow-dung, Iowa City and Mt. Pleasant. 



The species was found to be very common about Mt. Pleasant. 

 The plants when moist are pale reddish but when dry become 

 bright red and easily seen. The species is quite similar to the 

 preceding but differs in the habitat with slight differences in 

 morphological characters. 



LASIOBOLUS Saec, Bot. Cent. 18 : 220. 1884. 



Receptacle similar to that of Ascophanus but externally 

 clothed with sharp-pointed hairs. 



Two species collected in the state, one of which is very com- 

 mon. 



KEY TO THE SPECIES.

These plants have been collected in large quantities on the 

 usual (dung) substratum during the entire season. The plants 

 vary much in color so that this seems unreliable as a specific 

 character. They often occur densely crowded on the substratum 

 or more or less scattered. The paraphyses also vary much often 

 being branched several times and in other cases entirely un- 

 branched.
