FISTULINA. 255 



forming orbicular shields, variable in form from growing 

 into each other. (Fries.) 



Polyporus adiposus. B. & Br. 



Effuso-reflexed or entirely resupinate, soft ; pileus white, 

 usually tinged here and there with brown, minutely tomen- 

 tose ; hymenophore rather fleshy ; pores whitish, tinged in 

 places with brown, pores small, irregularly angular, very 

 shallow in resupinate forms, in the reflexed forms often 

 elongated and irregularly torn. 



Polyporus adiposus, Berk. & Broome, Ann. Nat. Hist., 

 n. 711 ; Stev., Brit. Fung., p. 201. 



On the ground near stumps and on trunks. Often 

 irregularly effused for several inches, with here and there 

 shortly reflexed portions, white with rusty stains here and 

 there. Pores where tolerably normal, about four in 1 mm., 

 rather fleshy and soft. The whole fungus turns brown on 

 drying. 



Polyporus armeniacus. Berk. 



Broadly effused, thin, flesh almost obsolete, margin downy ; 

 pores shallow, rounded, rather irregular, dissepiments thick, 

 pure white, changing to deep cinnamon during drying ; 

 spores colourless, elliptical, 7 X 4' 5 p. 



Polyporus armeniacus, Berk., Engl. Flor., vol. v. p. 147; 

 Stev., Brit. Fung., p. 215. 



Broadly effused and usually consisting in the large 

 patches of several confluent individuals. Margin often 

 sterile and byssoid. Pores average about ^ mm. in diameter. 

 Cooke considers that the present species is not distinct from 

 Polyporus amorphus, but the shape and size of the spores are 

 against this idea. 



FISTULINA. Bull. 



Hymenium formed on the under surface of a fleshy hy- 

 menophore, at first warted, the warts developing into 

 cylindrical tubes that remain distinct and free from each 

 other, and producing the tetrasporous basidia in their 

 interior. Conidia produced in cavities of the old hymeno- 

 phore.
