MINNESOTA MUSHROOMS 



TLUTEUS 



Closelv related to \' o 1 v a r i a, and distinguished from it only by the absence 

 of the volva. In both, cap and stem separate readily and the gills are free. The 

 last feature distinguishes P 1 u t e u s readily from E n t o 1 o m a, which resembles it. 

 Our species are all edible. They are found for the most part on stumps or decaying 

 wood, or in soil rich in woody material. The name refers to the form of the cap.
