THE STORY OF THE FUNGI 131 



{Amanita muscana). The abundant Chantar- 

 elle {Cantharellus cibarius) is a representative 

 of another type of the Agarics. Half a dozen 

 sub-families have been formed, and the dif- 

 ferent members are largely determined by the 

 colour of their spores. 



Additional families of the Hymenoniycetes , 

 in which the representatives are of very 

 distinctive appearance, may be briefly sum- 

 marised. In the case of the PolyporacecB a very 

 marked feature is that the spore-bearing sur- 

 face appears to have been covered with pin- 

 pricks. A typical species with which almost 

 everybody is familiar is the Bay Brown Boletus 

 {Boletus badius), which is very common, especi- 

 ally in fir woods. A normal form is bright brown 

 in colour on the top, and yellow on the spore- 

 bearing surface. Another branch of the family 

 is that which includes the woody bracket-like 

 fungi. These grow on many kinds of trees, 

 both hving and dead, and in the case of the 

 former are calculated to do a good deal of 

 harm. A typical species is the Soft Tinder 

 Fungus {Fames fomentarius) , which is of a 

 brown colour with a white spore-bearing surface. 



A very common fungus, Hydnum repandtim,
