POLYSTICTUS PINSITUS F^n'cs. 

 POLYSTICTUS GIBBERULOSUS I^ev. 



PoLYSTiCTUs sEMi-PLiCATUs B. and Macb., n. s. 



Pileus fan-shaped, or often resupinate with margin refiexed, 

 very thin, membranous i-i )^ cm. wide and long, white, 

 obscurely zonate behind, margin plicate-striate. Pores white, 

 sub-ano-ular. verv shallow, about the same as those of P. ver-

PoLYf^TicTus suB-GLABER £. and Macb.. n. s. 



Pileus thin, rigid when dry, 3 cm. long, 6 cm. wide, dirty 

 yellow, zonate and radiate-striate; margin spreading, and like 

 the fibrous flesh and the pores, rhubarb-yellow; flesh ver}- thin, 

 less than i mm. 



Pores minute, hardh' visible to the naked eye, 1-2 mm. 

 long, mouths stuffed with a white material which gives their 

 surface a grey tint. The smaller pores and the absence of 

 spines in the hvmenium will distinguish this from Mucrono- 

 porus licnoides Mont., which it in other respects resembles. 



PoLYSTiCTUS ALBiDUS Massec. 



POLYSTICTUS HIRSUTUS FvieS. 

 POLYSTICTUS LUTESCENS PerS. 



This differs in color only from ordinary specimens of P. 

 hirsntus. and is probabh* no more than a variety of that familiar 

 species.
