THE TUBE-BEARING FUNGI 



415 



Polystictus pcrcnnis. Vr. 



The pilens is thin, pliant when fresh but somewhat brittle when dry. It is 

 minutely velvety on the upper surface, reddish-brown or cinnamon in color; 

 expanded or umbilicate to nearly funnel-shaped. The surface is beautifully 

 marked by radiations and fine concentric zones. 



The stem is also velvety. The spore-tubes are minute, the walls thin and 

 acute, and the mouths angular, and at last more or less torn. The margin of the 

 cap is finely fimbriate, but in old specimens those hairs are apt to become rubbed 

 off. Atkinson. 



I found specimens by the roadside near Lone Tree Hill, near Chillicothe. 



Figure 345. Polystictus pergamenus. 



It is the only place in which I have found this plant. I have found Polystictus 

 subsericeus, or, as Prof. Atkinson calls it, P. cinnamomeus, in a number of 

 localities.
