ON THREE NEW SPECIES OF AGARICUS FROM A 



STOVE. 



By the Rev. M. J. Berkeley, M.A., F.L.S. 



It is pretty certain that most of the Hymenomycetous fungi 

 which occur in stoves are of exotic origin. A. cepcestlpes and an 

 allied similarly coloured species, which are the produce of our hot- 

 houses, occur naturally in hot countries, and have never been found 

 wild in Europe, and the same may be said of some others. The 

 three species at present described appear to be quite new, and one 

 of them is amongst the most interesting of the geous. 

 1. Agaxicus (Collybia) Doxotheae. 11. 



Pileo primum subgloboso fusco,dein applanato subumbonato palli- 

 diore, demum depresso usque ad centrum radiato-sulcato granulato, 

 setulis brevibus candidis sparso ; margine crenato ; stipite basi 

 ribrilloso luteo vel rufo, sursum candicante velut pileus granuloso- 

 hispidulo setuloso ; lamellis candidis distantibus adnexis leviter 

 ventricosis postice connexis, acie integra.
