PLATE XI. 



POISONOUS OR SUSPICIOUS BOLETI. 



i. Boletus felleus. Bitter Boletus. 2. Boletus alveolatus, Crimson Boletus. 3, 4. Boletus luridus, Lurid Boletus. 



FIGURE 1 above is very much like Figures 2 and 3, Plate VII., of Edible Mushrooms, from which it is easily distinguished by 



its bitter taste and rosy tubes. 

 FIGURE 2 is a distinctively American species, and the authority for suspecting it is found in the fact that all Boleti which 



have red or red-mouthed tubes have beeii considered poisonous. Although valuable for an illustration of the lurid 



Boleti, this variety is probably edible. 

 FIGURE 3 is easily confounded with Figures 4 and 5, Plate VII., cf Edible Mushrooms, if attention is not paid to the color of the 



tubes.
