i CLASSIFICATION OF AGARICS \ff? 



in coniferous woods. Bay View, Marquette and North Blba, Net? 

 York. August-September, [nfrequenl almost rare; 



Known l>\ its elongated Btem, which is usually rather stout and 

 tapering ;ii ili«' base; the young, conical pileus is scarcely wider 

 than the stem, h differs from related species in the shape of the 

 pileus. in dry weather the color is often pale violaceous, shading to 

 lavender and wheu old the pileus is likely to be split on the margin. 

 The violaceous aniversal veil collapses and forms thin and adn 

 annular patches above iIk' stem, scarcely ever forming a membran- 

 ous annulus as in C. umidicola. The description of our plants 

 differs somewhal from the European descriptions in the differently 

 shaped spores and stem although Pries says the Btem is Bometimes 

 attenuated below. The unpublished plate of Pries at the Stockholm 

 Museum shows a much deeper violel color than the figures of Cooke. 

 The inconsistency of the spore-sizes and spore shapes of European 

 authors indicates that the species is no1 clearly understood. Pries 

 states that the stem has the characteristics of C. <l<ili<>r l'r.. but, 

 except lor its mode of development, this is not strikingly apparent 

 in our plants. When deeply imbedded in moss the stems are very 

 long.
