FUNGUS-FLORA. 



Hydnum bicolor, Albertini & Schweinitz, p. 270; Stev., 

 Brit. Fung., p. 245. 



On pine wood, &c. 



At first sight might be easily confounded with reddish 

 form of Hydnum farinaceum, but when examined in the living 

 condition is seen to be altogether distinct. Subiculum very 

 thin, innate, slightly flocculose ; colour of the entire fungus 

 when living, reddish-white. (Fries.) 



Spines white, often 



or grey when old. 



Hydnum nodulosum. Fr. 



Whitish, smooth, inseparable, very broadly effused, nodu- 

 lose ; spines long, on the flat portions depressed, on the lower 

 surface of the nodules pendulous, upper side of nodules 

 barren. 



Hydnum nodulosum, Fries, Hym. Eur., p. 616; Stev., Fung., 

 p. 245. 



On trunks, fir stumps, &c. Often very broadly effused, 

 nodules variable in size, sterile above, bearing pendulous 

 elongated spines on the surface pointing to the ground. 



Hydnum Stevensoni. B. & Br. 



White, effused, mealy beneath, here and there byssoid ; 

 spines cylindrical, obtuse or truncate, sometimes compressed, 

 pulverulent at the apex; spores subglobose, apiculate, 

 colourless, 3-4 p diameter. 



Hydnum Stevensoni, B. & Br., Ann. Nat. Hist., n. 1437 ; 

 Stev., Fung., p. 246. 



On dead wood. Often effused for 2-3 in., very thin, 

 byssoid or pulverulent; spines rather crowded, sometimes 

 several more or less confluent at the base, variable, about 

 1^ line long. Sometimes spreading from the wood and 

 encrusting mosses, leaves, &c. 



Hydnum niveum. Pers. 



White, effused for 23 in., very thin, inseparable, margin 

 byssoid ; spines crowded, short, equal, glabrous. 



Hydnum niveum, Pers., Disp., t. 4, f. 6-7 ; Stev., Fung., 

 p. 246.
