MURRILL I POLYPORACEAE OF NORTH AMERICA 599 



ing logs in Honduras, Feb. 16, 1903. It resembles some plants 



called P. chrysites at Kew, but is quite distinct from that species. 



The shape of the spores as given above may be due to extreme 



desiccation. 



8. Inonotus pusillus sp. nov. 



Pileus sessile, convex, flabelliform, tapering to a narrow base, 

 erumpent from lenticels, 2 x 2 x 0.5-1 mm. ; surface ferruginous 

 to fulvous, silky-striate, subzonate, shining, margin pallid, acute, 

 often depressed : context thin, fibrous, ferruginous ; tubes urn- 

 brinous, comparatively large, 2-4 to a mm., polygonal, becoming 

 irregular, much exceeding in length the thickness of the context ; 

 mouths at first whitish-pulverulent, dissepiments thin, entire : 

 spores small, ovoid, 3.5 x 5 ft, pale ferruginous, copious, hyphae 

 concolorous. 



This species is based upon plants collected by Dr. Edward 

 Palmer, no. 1520,2k Manzanillo, Mexico, in 1892. The tiny 

 brown sporophores were found in large numbers emerging from 

 the lenticels of small dead branches of Jacquinia. It was appar- 

 ently recognized as a new species by Ellis and Galloway and dis- 

 tributed by them jointly under the genus-name Trametes, and later 

 listed by Patouillard (Tax. Hymen. 10 1. 1900) as a species of 

 Xanthochrous. The tentative name first proposed for the species 

 is here made use of, but according to present usage I am, unfortu- 

 nately, not permitted to cite the authors, since no description 

 accompanied the name. 



This is one of the very smallest plants met with in the Polypo- 

 raceae. Two other tiny plants are of interest in this connection, 

 Porodiscus pendulus, which is also erumpent from lenticels, but has 

 hyaline spores ; and Coltriciella dependens, which is more like the 

 present species in general appearance and structure, but is stipi- 

 tate instead of sessile, having the stipe attached to the vertex of 

 the pileus like the handle of a tiny bell.
