aperture. Stem yellow, often brightly colored with 

 the red of the cap. Chance cracks in its surface be-

 throughout the summer and autumn, and edible. 



In its brightly colored cap it might possibly be 

 superficially confounded with the suspicious Boletus 

 alveolatus of Plate 24. But the latter species is ea- 

 sily distinguished by its rose-colored spores and red 

 pore surface. 



CONE-LIKE BOLETUS 

 Strobilomyces strobilaceiis 



Another aUied species, not especially famous for its 

 esculent qualities, but which is, nevertheless, not to be

 brownish gray color, its shaggy surface more or less 

 studded with deep brown or black wool- 

 Botanical ly points, each at the centre of a scale-

 fragments hanging from the rim of the pileus. The 

 pore surface thus exposed is at first a grayish white, 

 ultimately becoming brown. The substance of the 

 fungus turns red when broken or cut. 



This very striking mushroom is found in woods, 

 especially under evergreens. It frequently attains a 

 diameter of four inches. Its spores are a deep 

 brown, and a specimen selected at the stage when the
