Plmit 3— 4" inches across, thick, oozing out from the tree in a very 



soft mass which hardens in a day, and if it dries favourably the pileus 

 becomes hispid. According to Fries, the figure of Sowerby represents 

 the species in an imperfect state, and tlien it is scarcely distinguishable 

 from P. hispidus except in colour. Tiie [)Iar.t figured in FL Dan. 

 grew upon beech.

 near Bridgenorth. Furton. — ''Pores very small and grey, even in 

 younger specimens always leaving a whitish margin on the under side 

 'which will readily di:,tinguish it." Sow. L c. Sowerby's original 

 specimens are now of a dull reddish-brown, with the tubes darker and 

 not extending to the niargin ; their substance bard and corky ; they 

 have scarcely any of the scorched appearance which is very remarkable
