which the pores are really black. I have never seen it from the southern United 

 States. The specimens so distributed by Ellis should have been referred to 

 Polystictus iodinus. 



POLYSTICTUS IODIXUS (Fig. 348). This is the same plant 

 as the preceding, excepting it has larger pores. The color is a lighter 

 shade of brown, and the color of pores and context are more uniform. 

 It was named from French Guiana, and seems to be the most common 

 form in northetti South America, the West Indies, and southern 

 United States.

 Polyslictus campyloporus. 



Form POLYSTICTUS CAMPYLOPORUS (Fig. 349). Known from a 

 single collection from French Guiana is only a form of Polystictus iodinus, 

 tending toward Cyclomyces fuscus. It is a curious fact that Cyclomyces fuscus, 

 which is common in the East Indies and occurs in Africa and the Philippines 

 with typically cyclomycoid gills, is absent from the American tropics, this form 

 being the nearest approach we have to it. 



POLYSTICTUS CICHORIACEUS (Fig. 350'). Pileus thin, 

 lobed, imbricate, with brown, velutinate, zoned surface. Pores rather 

 large, angular, dark. 



This species was originally from the Philippines and was named intybaceus. 

 The name was changed to cichoriaceus when it was found that intybaceus had 

 been used. I judge the name refers to the plant cichorium and its lobed leaves. 

 This, which is the most common species in the East Indies and the East in 

 general, I found abundantly in Samoa. It is thinner and more lobed than the 

 American plant Polystictus iodinus, which it otherwise closely resembles. 



POLYSTICTUS SETIPORUS (Fig. 351). This has the same sized pores 

 as Polystictus cichoriaceus and 1 think must be referred as a form. It is thicker 

 and more -even, which is the orriy difference I can note. It came from Ceylon.
