To those of my readers interested in the sci- 
ence of this spore -shower I give sectional illus- 
trations of examples of the two more common 
groups of mushrooms the Agaric, or gilled 
mushroom, and the Polyporus, or tube - bearing 
mushroom. The entire surface of both gills and 
pores is lined with the spore-bearing membrane, 
or hymenium, the spores falling directly beneath 
their point of departure as indicated ; in the case 
of the Agaric, in radiating lines in correspond- 
ence with the spaces between the gills, and in 
Polyporus in a tiny pile directly beneath the open- 
ing of each pore.
