Bitter Tube-Mushroom. Fig. 29.

(Boletus felleus.)617.

Said to be rare, but generally abundant in Epping Forest. I have found it in abundance in Nottinghamshire, and know it well; it was the first Boletus I ever drew, and I was then nearly eating it for Boletus edulis.

The bitter taste of B. felleus, the flesh-coloured tubes, the flesh-colour of the top when broken, the reticulated stem, and the pink spores are the distinguishing marks of this species. It is poisonous.
