basal point, creamy yellow, minutely bristly on the edge and sides 

 with the projecting hyaline pointed cystidia which are 60-80 // long, 

 15-20 iJ- broad. 



On decaying wood and bark, apparently of red maple, Acer 

 r u b r u m L. Sylvan Beach, Oneida co. July. 



This species is closely related to Pleurotus spiculifer 

 Berk., a species founded on specimens collected on decaying 

 wood on New Ireland island in the Pacific ocean, and described as 

 having the pileus very glabrous membranous and pellucidly striate, 

 characters not applicable to our specimens. For this reason we have 

 considered our mushroom distinct, though in other respects the 

 characters are very similar. Our specimens revive on the applica- 

 tion of moisture and then the flesh is colored like the surface of 

 the pileus and subgelatinous, .4-5 mm thick. When dry it is white, 

 slightly thinner, and appearing to have a thin upper gelatinous layer. 

 The spores are not known in our specimens nor described in 

 P. spiculifer. 



Pileus tenuis, lentus, subgelatinous, dimidiatus aut subflabelli- 

 formis, sessilis vel substipitatus, primo margine involutus, hirtus 

 praesertim ad basem, demum pruinosus vel subglaber, margine tenue 

 expanso vel leviter recurvato pallidus, griseo-brunneus vel fumoso- 

 brunneus, 6-12 mm latus; lamellae angustae, acie lateribusque 

 cystidiis minute setulosus ; cystidia hyalina lageniformia, 60-80 x 

 15-20 /x.
