Mycologia 



'hyaline, clavate, 2-spored ; 8-9x25-30 /jl; sterigmata 3-5 /x long; spores 

 subglobose, hyaline, 8-1 1 fi, verrucose, uniguttulate, often short-caudate; 

 odor fragrant. 



In clay soil under leaves of Quercus Garyana, Corvallis, Oregon. De- 

 cember. Rare. Collected by L. M. Boozer. No. 2208 (O. A. C. Herb. 



3393). 



The one fructification in the Corvallis collection is described above. 

 It follows very closely the original description of Gymnomyces pallidus 

 but the writer has not examined authentic specimens of this species. 

 This plant has nearest affinities with G. Gardneri Zeller & Dodge through 

 its spore characters, but is markedly different in that it has no columella. 

 The fragrant odor is that so characteristic of many fleshy polypores. 

 Gymnomyces pallidus has not been known outside of its type locality in 

 Tasmania.
