PORIA. 209 



Polyporus incarnatus, Fries, Syst. Myc. i. p. 378 ; Stev., 

 Brit, Fung., p. 213. 



On rotten pine and fir trunks. Often effused for 3-6 in. 

 in length, upper margin frequently shortly reflexed. Care 

 must be taken not to confound the present species with 

 Polystictus abietinus, which differs in the large, lacerated 

 violet pores, that eventually become pale and more or less 

 cinnamon colour. 



Effused, irregular, thin, coriaceous, marginate, or im- 

 marginate ; margin white, cottony, rather thick, as if there 

 was a tendency to become reflexed. Pores about ^ mm. 

 diameter, minute, very short, round, sub-equal, straight or 

 oblique, of a fine flesh-colour, approaching in some cases to 

 orange. Sometimes small cottony protuberances occtir 

 amongst the pores, which have the appearance of small 

 pilei with tubes underneath. (Grev.) 



Poria violacea. Fr. 



Effused, determinate, thin, violet-colour, closely adnate, 

 pores very shallow, cellular as if formed by upraised veins 

 or ridges, entire ; spores elliptical, 7 x 4 yu,., tinged yellow. 



Polyporus violaceus, Fries, Obs. ii. p. 263; Stev., Brit. 

 Fung., p. 212. 



On fir stumps, trunks, poles, &c. Somewhat resembling 

 Merulius in the shallow pores. Care must be taken not to 

 confound the present species with Polystictus abietinus, which 

 differs in the deeper torn pores, and is also usually more or 

 less reflexed. Pores from | f mm. across. 



Allied to Merulius, for which a young specimen might 

 easily be taken. (Cke.) 



Poria purpurea. Fr. 



Broadly and irregularly effused, the white flocculose 

 mycelium creeping over the surface of rotten wood and pro- 

 ducing here and there groups of minute, unequal, purple- 

 lilac pores about 1 line long. 



Polyporm purpureus, Fries, Syst. Myc. i. p. 379 ; Stev., 

 Brit. Fung., p. 212. 



On rotten trunks of beech and willow. Often broadly 

 effused. The violet colour usually disappears during drying. 

 Pores about mm. across.
