Fungi with Pores Boletaceae 



GENUS BOLETUS 



The species in the genus Boletus are numerous, and many 

 are extremely beautiful. They are distinguished from the other 

 pore-bearing fungi by the fact that their tubes are easily separable 

 from each other and from the portion on which they are borne. 



They are to be looked for in the warmest part of the season, 

 and with a few exceptions will be found on the ground. As it 

 is difficult to dry specimens so that they will retain their size, 

 shape, and colour, careful notes should be taken of these points, 

 together with the colour of the spores, the colour of the tubes, 

 the colour of the flesh before and after being bruised, the char- 

 acter of the stem, the presence or absence of hairs and fibres on 

 the several parts of the plant. The genus Boletus contains many 

 edible species, and also many which are dangerous ; and as the 

 recognition of the different species is a difficult matter, even for 

 experts, the beginner should be especially cautious. In general 

 it will be well to avoid for edible purposes all Boleti which 

 change colour on exposure to the air or on being pressed; all 

 those which have red-mouthed tubes, or mouths of a deeper 

 colour than the rest of the tube ; and all those with a peppery or 

 acrid taste. Experiment cautiously with the other species. 



A detailed description of the species is out of the question in 

 this book; for such the reader must refer to " Boleti of the United 

 States,"* or to " Fuhrer fur Pilzfreunde."f
