HuMARiA GRANULATA (Bull.) Sacc, Syll. Fung. 8: 129. 1889. 

 Peziza graniilata Bull., Champ. France 258. 1809. 

 Ascophamis gramdatus Speg., Michelia 1: 235. 1878. 

 Ascoholus granulatus Fuckel, Symb. Myc. 287. 1869. 



Plants sessile, scattered or crowded, at first globose, becoming 

 -expanded, externally coarsely granular; hymenium orange; asci 

 cylindrical, 8-spored; spores elliptical, smooth, 20 by lO^u; para- 

 physes clavate. 



On cow dung, Decorah. 



The only specimen seen is that in the Holway Collection in 

 the State College at Ames. 



HuMARiA LEUCOLOMA (Hedw.) Sacc, Syll. Fung. 8: 118. 1889. 

 Octospora leucoloma Hedw., Laub-Moose. 2 : 17. 1789. 

 Leucoloma hedwigii Fuckel, Symb. Myc. 317. 1869. 

 Aleuria leucoloma Gill., Diseom. 56. 1879. 



Plants gregarious, sessile, 1 to 5 mm. in diameter; hymenium 

 Tjright orange, slightly concave or plane ; asci cylindrical, 8- 

 spored; spores broad-elliptical, smooth, with one very large and 

 conspicuous oil-drop near the center, large, 20 by 12 to 15/x; 

 paraphyses enlarged upwards and filled with orange granules. 



On damp soil among moss, Iowa City and Mt. Pleasant. 



A common species on the margins of cinder walks overgrown 

 with moss, where they have been found up to the late fall after 

 the ground has been frozen. The plants are closely sessile so 

 that the hymenium is about even with the surface of the soil. 



The specimens listed in previous papers as H. humosa are 

 probably only a form of this species. The habitat of the two 

 is a little different as well as the size of the plants, but I can see 

 Tio difference in microscopic characters. 



PH.^OPEZIA Sacc, Michelia 1: 71. 1877. 



Plants fleshy or subfleshy, sessile, cup-shaped or nearly plane, 

 Tarely bright colored, smooth or hairy; asci elongated, 6 to 8- 

 spored; spores simple, elliptical, colored, greenish or brownish. 



One species rather common in the state.
