 7 cm. in diameter ; stem 4-5 cm. long by 2 cm. diameter. 



In drying, the entire plant as well as the gluten becomes black, 

 on the pileus a shining black. 



The spores are rusty to dark brown, or nearly black, fusoid or 

 oblong, and measure 15-22 x 5-6 //. 



In Fig. 50 a side and under view of the plant are given, and 

 in Fig. 51 a view after a portion of the lamella? have been peeled off,

showing how nicely the separation takes place, as well as showing 

 the forked character of the lamellae and the processes of the pileus, 

 which extend between the laminae of the lamellae. 



This plant seems to be very near Gomphidius glutinosm (Schaeff.), 

 Fr., if not identical with it, though the illustrations cited in Schaeffer 

 and in Krombholz seem to indicate a stouter plant. The descriptions 

 say nothing as to the appearance of the dried plant.
