In taste and smell A. silvaticus resembles A. silvicola, but is stronger. 

 It is a frequent but not common species in the localities where I have 

 found it. Quantities of it have not occurred, but myself and friends 

 have eaten it for years, knowing no distinction in effect between it and 

 allied species. Its strong taste requires that it be well cooked. It does 

 not lose its high flavor, which may be objectionable to some. I prefer 

 using its juices as a flavoring.

This is a small but symmetrical and beautiful Agaric. It is perhaps 

 too closely related to the preceding species (A. silvaticus) , of which it 

 may possibly prove to be a mere variety or dwarf form. Its pileus is 

 quite thin and fragile. Usually the darker or reddish hue of the disk 

 gradually loses itself in the paler color of the margin, but sometimes the 

 whole surface is tinged with red. Peck, 36th Rep. N. Y. State Bot.
