and not umbilicate pileus with a thick blunt margin, and a short, more

broad and 5 cm. high, with large angular whitish pores which are 
decurrent. On limbs, Heuer’s woods, Algoma. Rare. Neumann vid. 
Folyporus officinalis Fr. [Fomes laricis (Jacq.) M.] There is 
considerable doubt as to the correctness of the identification of the 
specimen referred to here on account of its having been collected in 
an apparently growing condition on a piece of slab of some coniferous 
wood lying in a damp woodshed. The context is chalk-white and has 
a very bitter taste like that of P. officinalis. July, Algoma. 
Folyporus osseus Kalch. Several pilei are closely imbricate, 
tapering downward to a common stipe-like portion. The flesh is soft 
and watery in fresh specimens, at first white, drying alutaceous and
