150 REPOBT OF THE STATE B0T4.NIST. 



The Cinnamon cortinarius is smaller than either of the forego- 

 ing spdcies, but it is more abundant. It is quite variable in size, 

 shape and color. The cap is generally convex at first, but often 

 expands until it is nearly flat. Sometimes it has a central prom- 

 inence or umbo. It is more or less coated, at least when young, 

 with minute silky fibrils, but sometimes becomes smoothish with 

 age. Its color is commonly cinnamon-brown, brownish-och- 

 raceous or tawny-brown. The gills are some shade of yellow 

 when young, except in one variety, but when mature they assume 

 the color of the spores. The stem is rather slender, often flex- 

 uous, fibrillose or silky, stuffed or hollow when old, and yellowish 

 or colored like the cap, or a little paler. 



In the Half-red variety. Variety seviisanguineus, figures 15 to 

 20, the young gills have a dark blood-red color This perhaps 

 ought to be considered a distinct species. 



The cap is usually one to two inches broad, the stem one to 

 three inches long and one-fourth of an inch thick or less. The 

 plant grows in woods or their borders, under trees or in mossy 

 swamps. Like many flowering plants which have a wide range 

 and are not particular as to their habitat, this mushroom is per- 

 plexing because of its variability, but it is believed that the de- 

 scription and figures here given will make it recognizable. The 

 fresh plant often has a slight odor like that of radishes. 



Paxillus Fr. 



The genus Paxillus is characterized by its gills which are 

 easily and smoothly separable from the cap just as the tubes of a 

 Boletus are, from the cap that supports them. They are reticu- 

 lately connected at the base in the single species here considered. 

 The spores are ochraceous. 



Paxillus involutus Fr. 



Involute Paxillus.
