 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 ja. 



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

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

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

 say nothing as to the appearance of the dried plant.
