70 EDIBLE AND POISONOUS MUSHROOMS. 



the flesh without the tubes, as the latter 

 are rather slimy. Young specimens are 

 best, when the flesh is firmest, as they are 

 disposed to become spongy with age'. On 

 the Continent the sliced caps are dried and 

 sold as "ceps," for winter use. It may be 

 observed that when cut down through the 

 stem the flesh undergoes little or no change 

 in colour, never turning blue, as in danger- 

 ous species. One plan of cooking is re- 

 commended which we have never tried — 

 that is, to fry or roast the sliced caps with 

 onions. Two or three other species of these 

 Boleti are excellent, especially one with a 

 rough dotted stem and dirty white under 

 surface of the cap, but the one above 

 described is most strongly recommended.
