In sandy fir woods. Chudleigh. [Low. & Mid. Carolina.] 



This species grows gregariously in srmdy fir woods ; when young it is al- 

 most transparent, and resembles young Cyaophallus caninus, being of a pure 

 white, and furnished with white roots, which proceed from a mycelium that 

 spreads sometimes an inch or two ; in this state it turns pink on being 

 touched ; in a more advanced stage it is yellow, but even then it has here 

 and there a pink tinge. The smell is very much like that of Melauogo.ster 

 amhiyuus when old, but when young it has an acid smell like that of sour 

 ham. It rapidly decays into a brown, foetid, pulpy mass. — M.J.B. Spores
