I have authentic specimens from Europe of this very rare and 

 interesting species reported by Dr. Kauffman as occurring in a 

 greenhouse in East Lansing, Michigan. Saccardo places it in 

 Inocybe and cites several synonyms. Patouillard classified it as a 

 Pholiota. It very much resembles some species of Lepiota that 

 turn red and have brown-tinted spores. Some of the figures also 

 show a booted stipe, as in Lepiota amianthina,
