Fries in Sys. Mycol. 2: 7. 1822 gives this as a subspecies 

 of AI. esculenta. Boudier in Histoire et Classification de Dis- 

 comycetes d'Eiirope gives conica as a distinct species and de- 

 scribes it as having a partially free pileus. It is evident that our 

 plant is the one described by Fries and not the species now often 

 described by Europeans as M. conica.
