where the spores are produced on the lower sur- 

 face of the cap. 



Class III. HYMENOMYCETES, OR 

 MEMBRANE FUNGI. 



This class is divided into six orders : 



1. Gill-bearing mushrooms, Agarics, or 

 Agaricini. 



2. Fungi with pores or tubes, Polyporei. 



3. Fungi with awl-shaped teeth or spines, 

 Hydnei. 



4. Fungi with an even spore-bearing or 

 slightly wrinkled surface, Thelephorei. 



5. Plants, club-shaped and simple, or bush- 

 like and branched, Clavariei. 



6. Gelatinous plants, irregularly expanded, 

 Tremellinei. 



The first order, the Agarics, contains most 

 of the well-known mushrooms, as well as most 

 of the edible ones. They have been divided 

 into different classes according to the color of 

 the spores. In a great many cases the color is 

 the same as that of the gills ; but this is not 

 always the case, especially in the young plants. 

 The Agarics are divided into four sections : 



1. White spores, Leucosporse.
