62 NATUEAL HISTOEY BULLETIN 



Plants small, 1 to 2 mm. in diameter, purplish, with a delicate 

 whitish margin ; hymenium slightly concave of about the same 

 color as the exterior; asci cylindrical, 8-spored; spores globose 

 entirely covered with large wart-like granules appearing very 

 rough; paraphyses slender a little enlarged. 



In woods among moss, Iowa City. 



The plants of this species are not quite so large as those de- 

 scribed by Quelet but the color and the spore-markings are char- 

 acteristic. The measurements given for the plants of this spe- 

 cies in the original description are 3 to 4 mm. in diameter while 

 our specimens scarcely exceed 2 mm. The verrucose markings 

 of the spores of the two specimens are very similar as is also the 

 color of the plants.

This species was described and illustrated in the Discomycetes 

 of Eastern Iowa with the note that it had not been found in Iowa 

 but was collected in the adjoining state of Illinois. The species 

 has not yet been collected in Iowa so far as known but is allowed 

 to remain in the list since the illustration occurs on an accom- 

 panying plate. This is the only species included in this list 

 which has not been actually collected in the state, this one having 

 been originally included as illustrative of this genus.
