Annual Report of the State Botanist. 25 



Boletus subvelutipes, Pk. ms. 

 Woods. Caroga and Catskill mountains. July. 



Polyporus piceinus, n. sp. 



Pileus 1 to 2 inches broad, thin subcorky, sessile, often concrescent 

 and imbricated, sometimes resupinate or effuso-reflexed, tomentose, 

 concentrically sulcate and adorned with intervening elevated tomen- 

 tose lines or narrow zones, tawny-brown or subspadiceous, the thin 

 margin at first golden-j'-ellow, soon tawny, then concolorous; hyme- 

 nium i^lane or concave, tawny-cinnamon, the pores minute, subrotund, 

 long, the dissepiments thin, but entire; spores minute, subglobose, 

 .00016 in. broad. 



Dead trunks and bark of spruce, Pioea nigra. Sandlake and Adiron- 

 dack mountains. July to October. 



This is a common species in regions where the spruce abounds, yet 

 it does not appear to have been described, nor does it appear to grow 

 on the trunk or bark of any other tree. The pileus often grows as if 

 attached by the vertex, and thus resembles in form the pileus of 

 Hymenochaete rubiginosa, or that of Trametes mollis. In color it resem- 

 bles Lenzites sepiaria and Trametes Pini, but it is generally a little 

 paler or more tawny. Sometimes the fungus appears to revive the 

 second year, and the pores are then obscurely stratose. This, with 

 the peculiar elevated lines of tomcntum on the pileus, suggests a 

 resemblance to Fomes pectinatus, but our plant would belong rntherto 

 the genus Polystictus, if the more recent genera into which the old 

 genus Polyporus has been subdivided should be adopted. In the 

 beginning a minute orbicular tuft of golden velvety hairs or fibres 

 appear. As this tuft enlarges pores are formed in the center just as 

 in Polyporus (Polystictus) abietinus, which sometimes accompanies it. 

 On the under side of prostrate trunks the fungus remains resupinate, 

 or has but a narrow reflexed margin, but in vertical situations a pileus 

 is formed. 



Polyporus aureonitens, Patouillard in lit. 



Pileus 6 to 18 lines broad, rather thick, corky, sessile, variously con- 

 crescent and imbricated, minutely velvety-pubescent when young, 

 soon glabrous, radiately fibrous-striate, the young plant and growing 

 margin at first sulphur-yellow, then golden-tawny, finally tawny-fer- 

 ruginous, generally concentrically marked with darker lines or narrow 

 zones, somewhat shining, substance tawny; pores minute, subrotund, 

 short, ferruginous with a silvery lustre; spores whitish, or very pale 

 yellowish, elliptical-naviculoid, .0002 in. long, .00010 broad.
