l82 EDIBLE MUSHROOMS 



ble monograph on the Boleti of the United States 



by State Botanist Professor Charles Peck, of Albany 



University, New York, which presents 



Works by detailed descriptions of one hundred 



Prof. Peck and eight indigenous species. Other 



contributions to mycological literature 



by this distinguished American authority are noted 



in my bibliographical list at the close of the volume. 



THE BOLETI 

 Tube mushrooms 



The Structure of these mushrooms is clearly shown 

 in Plate 38, in my chapter on " Spore -prints," the 

 hymenium being here spread upon the honey-combed 

 pore surfaces, and shedding its spores from the tubes. 

 Each of these tubes is distinct and may be separated 

 from the mass. 



The ideal form as shown in Plate 20 is perfectly 

 symmetrical, in which condition the pores would nat- 

 urally be perpendicular. But this perfection seldom 

 prevails, and we continually find the specimens more 

 or less eccentric in shape, especially where they are 

 crowded or have met with obstruction in growth. 

 But in any case, no matter what the angle or 

 distortion of growth during development, the tubes 

 are always adjusted to the perpendicular, or in mal- 

 formed individuals as nearly so as the conditions 

 will permit, as shown in the section on next page. 



The Boleti are in general a salubrious group. 

 Certain species have long been accredited as being 

 poisonous, and others excluded from the feast as "sus- 

 picious." The early authorities caution us to avoid
