Fungi with Pores—Boletacez 
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 Bolefié 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.” +
