206 FUNGUS-FLORA. 



The pores are of a pale delicate grey, with an acute, even 

 edge, about J„ of an inch in diameter. We cannot point out 

 any species to wliich it is allied. (B. & Br.) 



Bores about \ ram. across, angular, very shallow. 



Poria sanguinolenta. A. & S. 



Nodulose, soon confluent, effused, soft, white, but becoming 

 blood-red when touched ; the byssoid margin soon disappear- 

 ing : pores roundish, small, unequal, becoming torn. 



Poh/poriis sanquinohntus, Albertini and Schweinitz, Lusat., 

 p. 257 ; Stev., Brit. Fung., p. 218. 



On dead branches, rails, Szc. First appearing as small, 

 detached mycelioid tufts, which soon become confluent and 

 form a continuous, often broadly effused, thin stratum ; 

 sul^stance soft and becoming red at once when injured, in 

 this respect resembling Corticium sangnineum. Pores very 

 irregular in form, about ^ mm. across. The plant usually 

 contracts much during drj-ing, and is consequently torn into 

 in-egular patches. 



III. Pores white, tinged red or Jiesh-colour. 



Poria rhodella. Fr. 



Effused, soft, thin, closely attached to the matrix, white, 

 with a pink or rosy tinge, margin determinate, naked ; pores 

 minute, short, subrotund, not at all torn. 



Poljiporus rliodellus. Fries, Syst. Myc. i. p. 380 ; Stev., 

 Brit. Fung., p. 213. 



On trunks of beech, fir, &c. 



Poria micans. Fr. 



Effused, orliicular, usually becoming confluent, soft, white, 

 with a flesh-tinge ; margin white byssoid ; pores very 

 shallow, angular, resembling honeycomb, walls exceedingly 

 thin, somewhat toothed under a lens. 



Pohjijoriis micans. Fries, Syst. Myc. i. p. 383 ; Stev., Fung., 

 }). 213. 



On dead wood, rotten trunks, &c. Distinguished from 

 P. rhodelhis by the angular pores and white byssoid margin. 

 Pores very irregular in size and form, always angular, 

 ^— ^ mm. diameter.
