MINNESOTA MUSHROOMS 



PANAEOLUS 



In habitat. Panaeolus suggests C o p r i n u s. but it is readily distinguished 

 bv" the persistent gills. It is most readily separated from Psathyrella by the 

 absence of furrows or striations on the margin, and from Strop h aria, with 

 which it is often associated, by the black spores and the absence of a ring. The 

 species are very common on dung or in rich soil. Several of the species are edible, 

 but one or two still remain suspected. The name means variegated, and refers to 

 tlie mottled gills.
