Entirely resupinate, very thin, snow-wliite, mycelium 

 cobweb-like, somewhat pulverulent ; pores small, dissepi-

 colourless, 5 x 3 /x. 



Pohjporus hlepharistoma, B. & Br., Ann. Nat. Hist., n. 1434 ; 

 Stev., Brit. Fung., p. 220. 



On dead wood, branches, &c. Forming exceedingly thin, 

 persistently snow-white patches 1-2 iu. across. Pores 

 exceedingly shallow, about -^- mm. across. 



Poria farinella. Fr. 



White, broadly and irregularly effused, thin, mycelium 

 floccose or pulverulent, not interwoven ; pores forming a 

 continuous stratum, unequal, somewhat flexuous and intri-

Pohjporus farinellus. Fries, Syst. Myc. i. p. 384; Stev., 

 Brit. Fung., p. 220. 



On dead beech wood, &c. Very variable, almost dis- 

 appearing on being touched, with the substance of Corticium 

 sambuci. Pores about l- mm. across. 



Poria reticulata. Fr. 



Orbicular, white, thin, soon disappearing, margin floccose, 

 byssoid, radiating, pores distant, resembling cup-shaped

On rotten wood. The dissepiments of the rather large, 

 shallow pores resembling a network, pores about -^ mm. 

 across. 



Poria Vaillantii. Fr. 



White, thin, the cord-like spreading mycelium connected 

 imperfectly by a membranaceous exi:)ansion ; pores short, 

 rather large, unequal, produced here and there in clusters, 

 dissepiments thin. 



Pohjporus Vaillantii, Fries, Syst. Myc. i. p. 383; Stev.,

On dead wood. Perhaps an abnormal or imperfectly
