is in doubt. His N. A. F. 1306, on cedar, seems to me distinct, 

 although it was milk-white when young and fresh. Specimens 

 collected by me on spruce near Stockholm, Sweden, in 1910, and 

 determined by Romell, as well as by comparison with specimens 

 from Karsten, were described by me in the field as follows : 

 " Margin milk-white, slightly ragged and cobwebby ; hymenium 

 discolored at the center with brownish-chestnut tints as though 

 bruised or stained with blood. The discolorations are not bril- 

 liant, however, but look more like old blood stains." 



Bresadola reports the species from Hungary on poplar, beech, 

 and walnut. Specimens from Poland on pine are said by him to 

 be much thinner and quite distinct in appearance, being very sim- 

 ilar to P. violacea, with which he says this form is often con- 

 fused. According to him, the spores are 6-8 x 2-2.5 /*> an d the 

 hymenophore is at first white, then stained with red, drying in- 

 carnate, and becoming purple or violet-fuscous in the herbarium. 

 His idea of the species is quite different from Romell's and 

 Karsten's, and specimens so named from him appear very similar 

 to P. purpurea.

 wine-colored to lilac or rose-colored; context conspicuous, be- 

 coming rose-bay with age ; hymenium appearing in patches, but
