thickened marginal bands of adjacent gills arc in contact with 

 one another, so that a solid white cylinder is formed which en- 

 sheaths the stipe. It is important to notice that the gills, 

 except where they join at the membranous flesh of the pileus 

 and are in contact by means of the inner inflated marginal bands,

 hours older. All are shedding spores and undergoing autodigestion. The 

 pileus of the tallest has become reduced to one-half its original size and a 

 few drops of inky fluid have fallen from its recurved rim on to the pilei

are separated throughout their entire length (Plate I., Fig. 5). 

 In the spaces thus provided between the gills, the projecting 

 basidia can freely develop to maturity (Plate III., Fig. 14). It 

 thus happens that the spores of basidia, which belong to adjacent 

 gills, are never in danger of coming into actual contact and con-
