Hydnum geogenium, Fr. 



Woods. South Ballston. Aug. 



I am not aware that this rare and interesting species has before 

 been noticed in this country. According to Fries, the species is verv 

 variable, so much so that some specimens might be referred to the 

 section Pleuropoda, others to Mesopoda, ::nd others stiil to Apoda, 

 to which the typical form belongs. 



Hydnum farinaceum, Pers. 

 Decaying wood of hemlock. Osceola. Aug. 



Grandinia granulosa, Fr. 



Dead bark of alders. Karner. Sept. 



A variable species, referred to Thelephora by Albertina and 

 Schweinitz, to Hydnum by Persoon, and to Grandinia bv Fries.

Corticium puteanum, Fr. 

 Decaying wood in swamps. Guilderlaud. Sept. 



Corticium radiosum, Fr.

 rimose. The spores are elliptical.

Stem short, solid, dichotomously or subverticillately branched 5 

 branches slightly diverging or nearly parallel, nearly equal in length, 

 the ultimate ones terminating in two or more short acute concolo-

 Adirondack mountains. 



Tlie typical form has the branches numerous, nearly straight and
