PILEUS 1-2.5 cm. broad, rarelj broader, campanulate-convex or 

 subhemispherical, obtuse, seldom plane, hygrophanous, dark grayish 

 brown to smoky-fuscous and even vchen moist, Bometimes rufettcent, 

 subzonate on drying, drab-tan-color to buff when dry, glabrous, \<-il 

 entirely lacking. FLESH thin, dingy-pallid. GILLS adnate, al 

 most subdistant, broad, ventricose, Bometimes Binnate-emarginate, 

 purplish-fuscous or fuscons-brown, variegated, edge white-flmbriate. 

 STEM slender, is cm. long, 1.5-2 nun. thick, equal, rigid-elastic, 

 fragile, hollow, even, glabrous, pruinose a1 apex, pallid to subru 

 fescent, no1 rooting. SPORES variable in size, L3-18x8-10 inicr., 

 broadly elliptical, or in another plane broader a1 our end, slightly 

 tuberculate, apiculate, purplish-brown under the microscope. 

 CYSTIDIA none. STERILE CELLS on edge, aarrow, 30-36x3-5 

 micr. ODOR and TASTE none. 



Gregarious or scattered, among grass on lawns, roadsides, grass] 



places in w Is. meadows ami pastures. Throughout the State. 



May-June (less often, July-September). Very common. 



The "haymarker's Psilocybe" is to be looked for during the warm 

 spring months on our lawns everywhere. Its colors are dull and 

 quite variable, but because of its abundance it can booh be re< 

 nized under its many guises. A zonate effecl is often seen on the 

 pileus as the moisture dries out. h is edible. The Bpore-sizea 

 given incorrectly by several authors, bul this is nol surprising be 

 cause of their ureat variability, c\cn in the same plant. The rough 

 character of the surface of the spore distinguishes if from the 

 others.
