206 FUNGUS-FLORA. 



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

 -edge, about ^ of an inch in diameter. We cannot point out 

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



Pores about ^- mm. 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. 



Polyporus sanguinolentus, Albertini and Schweinitz, Lusat., 

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



On dead branches, rails, &c. First appearing as small, 

 detached mycelioid tufts, which soon become confluent and 

 form a continuous, often broadly effused, thin stratum ; 

 substance soft and becoming red at once when injured, in 

 this respect resembling Corticium sanguineum. Pores very 

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

 contracts much during drying, and is consequently torn into 

 irregular patches. 



III. Pores white, tinged red or flesh-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. 



Polyporus rhodellus, Fries, Syst. Myc. i. p. 380; Stev., 

 Brit. Fung., p. 213. 



On trunks of beech, fir, &c. 



Poria micans. Fr. 



Effused, orbicular, 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. 



Polyporus micam, Fries, Syst. Myc. i. p. 383 ; Stev., Fung., 

 p. 213. 



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

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

 Pores very irregular in size and form, always angular, 

 mm. diameter.
