IOWA disco:mtcetes 51 



paraplivses filiform, slender, enlarged upwards and filled with 

 orange granules. 



On the ground among moss, Iowa City, common. Also ob- 

 served and studied in Indiana. 



The plants of this species are smaller than in the preceding, the 

 hymenium at maturity always convex and without definite mar- 

 gin. The spore-markings are characteristic on account of their 

 irregularity and the larger size of the meshes. The species is 

 very common and so far has always been found among moss- 

 plants in gardens and open fields.

Plants similar in size and general appearance to the preceding, 

 entirely smooth, pale orange to salmon-colored, growing in thick 

 groups but never crowded; asci cylindrical. S-spored: spores 

 globose, clothed externally with nimierous minute, sharp spines 

 which are often bent in various ways, seldom entirely straight. 

 15 to 18^ in diameter: paraphyses filiform or a little enlarged. 



On naked clay soil among tufts of grass. Iowa City. Common 

 in one locality. 



The plants of this species occurred in one locality in great 

 ntimbers and were studied during the entire season. The habi- 

 tat and pale yellow color of the plants seems to be quite charac- 

 teristic and the spore-markings are still more so. The minute 

 spines with which the spore is covered are very sharp and many 

 of them crooked and bent in various ways. The drawings of the 

 forms collected, which were made before leaving Iowa, compare 

 very favorably with those accompanying the original descrip- 

 tion which has since been examined.
