42 MUSHEOOMS. 



Section 1. WHITE SPORES, OR LEUCOSPORJE. 

 The first genus we will mention is : 



HYG-ROPHORUS, from a word meaning moist. 



This genus contains plants growing on the 

 ground. They soon decay. The cap is sticky 

 or watery, the gills often branched. It has a 

 peculiarity in the fact that the hymenial cells, 

 or the layer of mother cells, contained in the 

 gills, change into a waxy mass, at length re- 

 movable from the trama. The trama is that 

 substance which extends with and is like in 

 structure to the layer of mother cells. 1 It lies 

 between the two layers of gills in Agarics. 

 The gills seem full of watery juice, and they are 

 more or less decurrent, i. e., extend down the 

 stem. This genus contains many bright- 

 colored and shining species. 



We are obliged to refer to the hymenial layer 

 in this place, though the beginner will scarcely 

 understand the meaning of the term. The dis- 

 tinguishing peculiarity of this genus consists 

 in the cells changing to a waxy mass. In the 

 chapter on the structure of mushrooms we have 



1 In the young plant it forms the framework of the gills.
