. HYDNUM. 155 



In pine woods. Gregarious and often confluent. Margin 

 white when in full vigour ; flesh black. 



Inodorous, woody. Pileus unequal, flattened and depressed, 

 with a whitish margin, spines slender, equal, becoming 

 cinereous. Very distinct and easily recognised by its black, 

 zoneless flesh. Spores white, round, papillose, diameter 

 00017 in. In my specimens of this species the pileus is 

 distinctly zoned, as it is in Fries' own figure in his recently 

 published Iconee. (W. G. Smith.) 



Hydnum graveolens. Delast. 



With an odour like melilot. Pileus 1-1^ in. across, 

 coriaceous, thin, soft, zoneless, rugulose, smooth, blackish- 

 brown, grey when dry, margin pale, flesh brownish ; spines 

 decurrent, short, grey; stem 1-1^ inch long, about 1 line 

 thick, tough, blackish-bi-own, polished.

 F. Brit., p. 238. 



In fir woods. Gregarious, retaining its scent for years. 



When fresh it is extremely beautiful, being dark in the 

 centre with a white border. The spines are pale, and the 

 spores evidently white. The whole plant smells extremely 

 strong of melilot, and after it has been dried three or four 

 years the scent is as strong as ever. (B. & Br.) 



Hydnum melaleucum. Fr. 



Pileus plane, 1-1 in. across, thin, rigid, dry, irregular, 

 striate, with little elevations at the centre, black, margin 

 white ; spines short, white ; stem ^-J in. long-, slender, 

 smooth, black ; spores globose, 2 5-3 p. diam.
