2. Hydnum albo-magnum Banker 



Plates 3 axd 27. 



Cap up to 11 cm. broad, more or less wavy, the center usually de- 

 pressed and margin lobed, surface smootliisli or minutely velvety in 

 places, adhering to trash when young, but this seems due to the surface 

 layer growing around and into the trash rather than to viscidity, as 

 each twig and pine leaf is lying in a little trough and there is no 

 noticeable viscidity at maturity even when soaked ; color pure white 

 or creamy in places, not changing color when rubbed. Flesh up to 

 1.4 cm. thick, abruptly narrowed to the thin margin which scarcely 

 extends beyond the spines. It is pure white, solid, but rather soft and 

 fragile, taste sweetish and quite pleasant, odor faintly aromatic. The 

 upper 2 or 3 mm. of the flesh, which cannot be distinguished from 

 the rest when not soaked, will immediately imbibe a large amount of 

 water and become clear and translucent, in sharp contrast to the non- 

 bibulous opaque white part beneath. 



Spines up to 5 mm. long towards center, shortening towards margin, 

 but the long ones also having much shorter ones mixed among them. 

 They are slender, sharp pointed, about 1/3-1/2 nun. thick at base, 

 fragile and easily breaking away from the cap, only slightly decurrent. 



Stem short, central or eccentric, expanding above into tlic ca]), 

 pointed below, about 1.5 cm. thick in middle; texture solid and
