Solitary or loosely gregarious, inodorous, very variable ; 

 pileus rufous-bay, yellowish, or tan-colour; in dry pine 

 woods a form occurs having a white pileus and gills and a 

 3'ellow stem. Gills sometimes sulphur-colour, and some- 

 times (a morbid state) cinnamon-tan. The following forms 

 •occur : — 



(A.) Stem elongated, flexuous, decumbent, base swollen ; 

 pileus broad, lobed, gills white : — 



(5.) funicularis, large tufted ; stem lax, decumbent, base 

 equal, downy; gills sulphur-colour: — 



(C) Numerous individuals growing together in a large 

 tuft; stem thick, swollen, deformed, sulcate, brown, myce-
