The following species are extra-limital. Specimens of them 

 have been sent to me for identification, but I find no descriptions 

 that harmonize with their characters. They are therefore 

 recorded here as new species. 



Mycena strobilinoidea n. sp. 



Pileus thin, subcampanulate, obtuse, glabrous, bright scarlet ; 

 lamellae whitish, reddish on the edge ; stem short, glabrous but 

 with a tawny villosity at the base, colored like but a little paler 

 than the pileus. 



Pileus 4 to 6 lines broad ; stem about 1 inch long. 



Under Abies subalpina. Olympia mountain, Washington. 

 ''Appearing soon after the snow disappears," L. F. Henderson. 



The species belongs to the section Calodontes, and is distin- 

 guished from M. strohilina by its obtuse pileus and the colored 

 villosity at the base of the stem.
