IrfHydnitm, the fruiting-surface consists of distinct spines 

 which are often somewhat branched at the tips. They vary 

 greatly in form, and the species are difficult of determination 

 because of a lack of technical American literature upon this 

 group. They grow on the ground or upon wood, usually in 

 woodlands. They are especially frequent as fall approaches, 

 and many of the earth-growing species are overlooked by the 

 collector because of their resemblance in color to fallen leaves. 

 Several of the wood-growing plants are beautifully tufted into 

 coral forms, thus resembling Clavariaceae, but their spines al- 

 ways point downward, never upward as do the Clavarias. 



Many species are listed as edible.
