,,_,, THE AGARICACEAE OF MICHIGAN 



while VOLVA. SPORES spherical, 8-10 micr. diam., nucleate by 

 a large oil-globule, smooth, white. 



Solitary or scattered. In conifer or frondose forests; in open, 

 low woods; in copses, sometimes on much decayed wood. July, 

 August and September, rarely earlier or later. Throughout the 

 Stale Very common. Edible. 



In some localities the white and tawny forms prevail, as at Ann 

 Arbor ; in others, especially in conifer regions, the tawny and livid 

 forms are found more commonly. The pileus and stem are rather 

 fragile, and the volva is apt to break and adhere to the soil so 

 that the extracted stem appears to be without a volva. The varia- 

 tion in size and color seems to be greater in Europe than with 

 us; Secretan differentiated ten forms and raised them to the rank 

 of species. The spores of our plants, at least of the fulvous form, 

 are always spherical, with an obscure angle on the apiculus side. 

 Saccardo gives them ovate and 10-15 micr. long, and Patouillard 

 figures them ovoid. Quelet and Battaile agree with us, calling them 

 spherical and 10 micr. diam. The gray form must not be confused 

 with Amanita spreta Pk. which is also without a bulbous stem. The 

 beaut}' and symmetry of the different forms are a constant delight 

 to the field botanist. 



Section IT. Universal veil breaking into floccose or powdery 

 scales or fragments, which cover the pileus and base of stem.
