CLASSIFICATION 387 



T. pini. — More or less semicircular, concentrically grooved, rough, 

 rusty brown, 3-4 in. across, flesh rusty, liard ; tubes long ; pores 

 irregular, small, rusty. 



On living pine trunks. A destructive parasite. , 



T. gibhosa. — About semicircular, horizontal, concentrically zoned, 

 velvety, whitish, corky, 2-4 in. across ; tubes about \ in. deep ; 

 pores small, elongated radially. 



Often with a green tinge due to the presence of minute algae. 



On stumps, trunks, posts, etc. 



2\ biiUiardi. — Semicircular, thick at point of attachment, free 

 edge ttiin, white, then brownish and zoned ; tubes about \ in. deep ; 

 pores roundish. 



Smell fragrant. Flesh wood-colour. 



On dead wood. 



T. suaveolcns (PI. XXXI, fig. i).— Semicircular, thick 1 ehind, 

 edge thin, downy, whitish, 3-6 in. across, flesh white, corky ; tubes 

 I in. or more in length ; pores rounded, large, white, then brownish. 



Smell spicy. 



On trunks, especially willow. Smell like aniseed. 



T. odoyata. — Dimidiate, at first somewhat corky, rather soft and 

 downy externally, and the flesh fulvous, becoming vaguely con- 

 centrically zoned, rugulose, tomentose and blackish umber, 3-5 in. 

 long, 2-3 in. broad, edge and the rather large, subrotund pores 

 tawny cinnamon. Odour rather strong, spicy. 



Distinguished by the blackish umber, coarsely rugulose cap, 

 spicy smell, and the fairly large pores. The general surface of the 

 hymenium is generally very uneven, certain groups of tubes pro- 

 jecting beyond the general surface here and there. The hymenium 

 is usually more or less decurrent, sometimes running down the sub- 

 stratum for 2-3 inches. The cap is generally dimidiate, and attached 

 by a broad base ; sometimes, however, the point of attachment is 

 narrowed behind. Known from our other scented species by the 

 blackish brown cap and coloured flesh. 



British specimens of this species have been erroneously referred 

 to Polyporus bcnziniis. 



On decaying coniferous wood in the New Forest. Apparently 

 very rare. 



T. odora. — Semicircular, thick behind, narrowing to a thin edge, 

 \vhitish, even, downy, 2-4 in. across, flesh corky, whitish ; tubes 

 up to \ in. deep ; pores round, small. Smell spicy. 



Differs from T. siiaveolens in the smaller, shorter, round pores. 



On willow. 



T. inodora. — Semicircular, whitish, tapering to a thin edge ; 

 pores subangular or often elongated. Inodorous. 



Distinguished among the white species by the absence of smell. 



On stumps, trunks, etc.
