Ground among fallen leaves in woods. Lewis co. September. 



This is a rare species which departs from the generic character 

 in its decurrent lamellae. It is unlike any of our other species of 

 Inocybe in its minute globose spores. These have been described 

 in SyJloge as echinulate, but in our plant the spores appear even 

 under ordinary magnification, most minutely uneven under higher 

 power or better definition. By some, the species has been referred 

 to the genus Flammula. It has also been taken as the type species 

 of a-genus Ripartites, instituted by Karsten to include all the species 

 of this section.
