 paratively high temperature, are apt to be very ripe, so that the 

 gills are black from over-ripe spores, and are thus somewhat un- 

 sightly. Those grown at a lower temperature, as is the case in 

 some mines, do not blacken so soon, and are therefore apt to be free 

 from this objection. Another objection, however, is on the part of
