CHAPTER VIII: FUNGI WITH PORES— 
BOLETACEA:; POLYPORACEAE 
THE fungi with pores naturally divide into two groups. 
The perishable fleshy fungi with pores easily separating from 
the cap and from each other make the family Boletacew. The 
perishable fleshy fungi, and the leathery, corky, membranous 
or woody fungi, with pores permanently united to the cap and 
to each other, make up the family Poly- 
») poracee. In each the spores are borne on 
the linings of pores or tubes placed close 
together, so that on the surface of the cap they 
look much like large pin pricks on a stiff 
cushion ; but in a sectional view, obtained by cutting the cap 
from the upper surface to the lower, they look like tubes placed 
side by side. 
Among the fleshy forms the genus Fistulina has the stem 
lateral and the tubes close together, but distinct from each other. 
The genus Boletus has the tubes easily separable from the cap, 
and the genera Boletinus and Strobilomyces have the tubes quite 
firmly connected. A brief comparison of essential points is 
given in the table.

GENUS FISTULINA 
The genus Fistulina contains one notable species, Fistulina 
hepatica, so called from its resemblance to a liver. In its early 
stages it somewhat resembles a strawberry, and later it may
