POLYPORUS ELLISII . Pileus when fresh sulphur-yellow with 

 large, dense, fasciculate warts. Flesh white, when dry discolored. 

 Pores when young white, angular, decurrent becoming sinuate and 

 somewhat irpicoid when old. Color when fresh is white, changing 

 to greenish when wounded. In the dried plant they are darker than 

 the pileus. Spores (teste Underwood) oval, 6x9, smooth. 



This is one of the rarest of American species. I think it is known from 

 but three collections, made many years ago, viz : Ellis in New Jersey, Ravenel 

 in South Carolina, and Underwood in Alabama. An illustration was given in 

 our Polyporoid Series, page 29. 



POLYPORUS SQUAMATUS (Fig. 505). Pileus mesopodial, fleshy, cov- 

 ered with large cone-like scales. Pores large, angular. Color of the dried plant 

 dark, almost black, excepting the pores, which take a red color similar to that

 made in Hungary by Kalchbrenner and determined as Polyporus ovinus. Si '

MELANOPUS. 



The species with black stipes were separated by Fries into a distinct section 

 which he called Pleuropus. If confined to the plants of Europe, it is not a 

 bad section as they can all be referred as forms of two species, viz : squamosus 

 and varius. In foreign countries however it would include such species as 

 Polyporus radicatus of the United States and tumulosus of Australia and others 

 that have little relation to these plants of Europe and which we feel are much 

 better classed in the section Ovinus. We would therefore divide the species that 

 Fries separated as Pleuropus between the sections Ovinus and Lentus of Fries.
