which it is usually confused. The recorded range is New York, 

 Michigan and Alabama. 



Coufal, Johnson county (Miss Macbride). 



13. H. ZOXATUM (Batsch) P. Karsten (Hydnum zonatum Batsch.) 



Also represented by a single collection which includes but one 

 sporophore. While apparently very close to the last species 

 it is very easily distinguished from it by the larger and thicker 

 pileus. 



Hesper, Winneshiek county (Shimek). 



VI. Al KISCALPIUM S. F. Gray. 



In the present genus the pileus has a deep sinus on one side 

 with the stipe so inserted in the sinus as to give it a lateral ap- 

 pearanee while the stipe continues on the top of the pileus as 

 a. distinct ridge which runs out gradually, but extends well 

 a cress the pileus. A very interesting monotypic genus. 



14. A. VULGARE P. Karsten. (Hydnum Aurisealpium L., 

 A. Aurisealpium S. F. Gray.) 



This species is recorded from Iowa by Banker 10 who gives 

 its habitat as "decaying cones of Conifers." Our specimens 

 are probably from the same collection as his Iowa material, 

 but do not show the substratum further than that the base 

 of the stipe is covered with moss. The label reads "On the 

 ground. Rare." Not to be confused with any other species of 

 the family on account of the peculiar insertion of the stipe. 



Iowa (Macbride). 



VII. GMODON P. Karsten. 



A very distinct genus characterized by the papillate, light- 

 colored spores and the sessile or resupinate branched pileus. 

 Monotypic. j 



15. G. STRIGOSUM (Swartz) P. Karsten. (Leaia piperata Banker, 

 Hydnum strigosum Swartz.) 



Not represented in the University herbarium but recorded 

 by Banker 11 as being collected in Iowa by Holway.
