MUSHROOMS, EDIBLE AND OTHERWISE 



light-brown ; margin extending beyond the gills, as will be seen in Figure 249 

 in the one on the extreme right. 



The gills, when first revealed by the separation of the veil, are of a delicate 

 pink hue, but with advancing age this generally deepens to a dark-brown or 

 blackish-brown color. 



The stem is rather short, nearly equal, white or whitish; the substance in 

 the center is more spongy than the exterior, hence it is said to be stuffed. Some- 

 times the collar shrivels so much that it is scarcely perceptible, and may disappear 

 altogether in old plants. The spores are brown in mass. The cap of this 

 mushroom is from three to four inches in diameter and the stem from one to 

 three inches long. 



This is the first mushroom that yielded to cultivation. It is raised in large 

 quantities, not only in this country, but especially in France, Japan, and China. 

 No doubt other species and genera will be produced in time. 



This species grows in grassy places, in pastures, and richly manured grounds, 

 never in the woods. I found it in great abundance in Wood County, in fields 

 which had never been plowed and where the ground was unusually rich. There it 

 seemed to grow in groups or large clusters. Usually it is found singly. Found 

 from August to October. The plants figured here were found near Chillicothe.

 Rodman's Mushroom. Edible. 



The pileus is creamy, with brownish spots, firm, surface dry. The mature 

 specimens frequently have the surface, of the cap broken into large, brownish 

 scales. 



The gills are whitish, then pink, becoming dark-brown: narrow, close and 

 unequal.
