264 THE AGARICACEAE OF MICHIGAN 



Throughout the State. May to September. (Earliest record May 

 30.) Very common during rainy seasons in early summer. 



This is probably the American form of H. candolleanum Fr. The 

 single phrase, "gills at first violaceous," in Fries' description de- 

 terred Peck from referring it there. Ricken says "gills at first 

 white, then sordid-rosy or violaceous"; this gives the gill-colors of 

 the European plant without a doubt, and this condition is not much 

 different from that in our plants. As in H. sublateritium, the gill- 

 color varies somewhat with the conditions surrounding the develop- 

 ment of the plant. Because of the abundance of individuals usually 

 found in a patch, its well-known edibility makes it a plant much 

 sought after. Although the caps are thin, the meat is crisp and 

 of delicate flavor and it often grows at our very doors in the grass 

 over some old hidden remains of a stump. This is also presumably 

 the E. apperidiculatum of many American authors. 



A variety occurs in the woods, which only differs in that the 

 plants are mostly solitary and long-stemmed, scattered here and 

 there among decayed sticks or leaves; its spores are perhaps slightly 

 longer and slightly variable in shape, but otherwise it is very similar. 

 It may be called var. sylvestris.
