CHAPTER VI: FUNG! WITH TEETH— 
HYDNACE/E 
Tue fungi with teeth are so called because, instead of bear- 
ing their spores on the surface of gills and pores, they bear 
them on the surface of awl-shaped teeth, which project down- 
ward. The genera of the family Hydnacee are distinguished 
by the size, shape, and attachment of the teeth. Plants with 
teeth only, and no basal membrane, make the genus Mucronella. 
Plants with flattened, leaf-like teeth attached to a leathery mem- 
brane, growing on wood, either in the form of a cap, or simply 
spreading over the host, make the genus /rpex. Plants with 
thick, blunt, irregular spines make the genus Radulum. Fleshy 
or membranous plants with caps and flattened teeth, growing on 
the ground, make the genus Sistotrema. Plants which spread 
over their host, closely attached to its surface, and have simple, 
bristle-like teeth, make the genus Pycnodon. Plants growing 
in a manner similar to those of the genus Pycnodon, but having 
low-crested wrinkles instead of bristles, make the genus 
Phlebia ; while those with smooth hemispherical warts make 
the genus Grandinia, and those with crested papillose warts 
make the genus Odontium. The typical genus Hydnum has the 
teeth cylindrical, so that a cross section would appear circular. 
This is the only large genus, and in it are found several impor- 
tant edible species. These may be put in two groups, one con- 
taining the species with a cap and central stem, and one the 
species grc wing in branched masses with no distinct cap. These 
are commonly known as Hedgehog Mushrooms.
