112 PROCEEDINGS OF THE AMERICAN ACADEMY 



purpureas, csespitosus, pusillus ; pileo e convexo piano glabrato ; stipite 

 gracili ; lamellis crassis adnatis. 



Shady hill-sides, Bonin Islands. — Allied to A. onychinus. 



6. A. (Colltbia) talpinus, Berk. & Curt.: flavidus ; pileo tenui 

 stipiteque basi strigoso-radiato subtiliter velutinis ; lamellis angustis- 

 simis adnexis. 



On decayed wood, Bonin Islands. — Allied to A. velutipes. 



7. A. (Collybia) palmicola. Berk. & Curt. : pusillus ; pileo 

 convexo glabro aurantiaco margine inflexo ; stipite subconcolore glabro 

 basi radiato-strigoso ; lamellis adnexis crassiusculis paliidioribus. 



On dead Palms, &c., Bonin Islands. 



8. A. (Colltbia) efflorescens, Berk. & Curt. : flavidus ; pileo 

 planiusculo stipiteque sursum dilatato subtiliter pulverulento-velutinis ; 

 lamellis liberis modice latis venoso-connexis. 



On decayed wood, Bonin Islands. — Allied to A. velutipes, but far 

 less velvety. We believe it is Marasmius rufus of Montague. 



9. A. (Collybia) poigenl's. Berk. & Curt.: fuscus; pileo hemi- 

 sphferico striato glabro ; stipite insititio deorsum velutino ; lamellis ad- 

 nexis subdistantibus. 



On dead grass. Hong Kong. — Has the habit of A. stipitarius. 



10. A. (Collybia) adianticeps. Berk. & Curt.: flavidus; pileo 

 demum depresso striato, margine crenato appendiculato ; stipite carti- 

 lagineo isquali ; lamellis angustis adnexis. 



Hill-sides, Hakodadi, Japan. — The pileus of this pretty species looks 

 very much like the frond of an Adiantum, from its long strise, and 

 crenate, appendiculate margin. 



11. A. (Mycexa) Californiensis, Berk. & Curt.: pileo ex conico 

 breviter campanulato stipiteque gracili rufis ; lamellis liberis albis 

 rubro-marginatis. 



On Oak leaves, Mare Island, California. — Differs from A. auran- 

 tio-marginatus in the nature of the gills, and is a more graceful species. 



12. A. (Mycena) alphitophyllus. Berk. & Curt. : pileo leviter 

 depresso molli succulento viscoso albo ; stipite brevi rufescente ; la- 

 mellis latiusculis distantibus adnexi-decurrentibus pulverulentis ; sporis 

 mafirnis globosis. 



On decayed logs, Bonin Islands. — This may perhaps be the type 

 of a distinct genus. The spores are very peculiar, as also the manner 

 in which the gills separate below, reminding one of Paxillus.
