Collection, Description and Identification of the Specified Fungal Flora in the Western and Central Himalayas up to Kathmandu in Nepal: (Polyporaceae)

Pp. (ii), 70.  Original pale green wrappers, lettered in black on the front cover, 4to.  The Polyporaceae are a family of poroid fungi belonging to the Basidiomycota.  The flesh of their fruit bodies varies from soft (as in the case of the dryad's saddle illustrated) to very tough.  Most members of this family have their hymenium (fertile layer) in vertical pores on the underside of the caps, but some of them have gills (e.g. Panus) or gill-like structures (such as Daedaleopsis, whose elongated pores form a corky labyrinth) (from Wiki).  This volume is from the private research collection of University of Michigan mycologist Alexander H. Smith.
