C.^ Flesh and veil tawny; pileus tawny-red. S. 1034; St. 

 320; M. 114; J. M. 14: 66. 



H. pyrotrichum Holmsk. 

 Notes. 



H. perplexnm is regarded by a number of writers as not 

 specifically distinct from H. sublateritium. H. incertum is some- 

 times regarded as a variety of H. candolleanum. 



Morgan lists H. candolleanum as H. mutabile Fl, D. and 

 H. sublateritium as H. lateritium Schaeff. 



H. comaropsis Mont. (S. 1036), described from Sullivant's 

 material has not since been recognized.
