SECTION PETALOIDES. 



24. POLYPORUS (CORRESPONDING TO POLYSTICTUS, 



BUT THICKER) WITH COLOR AND PORES OF 



THE SECTION MICROPORUS. 



VERNICIPES (Fig. 448). Pileus smooth, rugulose, faintly 

 zonate, shiny, thick, 2-3 mm., rigid. Pores minute. Specimens from 

 Japan, Philippines, and Africa. 



SUBFULVUS. Plant smooth, rigid, pale ochraceous, smooth, 

 with a short, thick, sublateral stem. Pores concolorous, minute, rigid, 

 2-3 mm. long. Specimens (Wright 135 & 355) at Kew from Cuba, 

 published as ochrotinctus of Bonin Island. Subfulvus was Berkeley's 

 manuscript name and a good name for it. 



SIENNAECOLOR. Comparable to a thick specimen of Polystictus luteus. 

 Same color and pores, but on the Polyporus order with a thick, short, dorsal 

 stem. Known from one specimen from Ceylon. The Brazilian specimen cited 

 was something else I think. 



25. RED SPECIES. 



SANGUINEUS. Perhaps no other one species is as abundant 

 in the museums as this. It is the common red species that grows in 

 every warm country of the world. It is strangely rare in Samoa, 

 however. A short, lateral stem, often disci form at the base, is a 

 feature of most collections, but not always, as museum specimens are 

 sessile and even dimidiate. It is close to Polystictus cinnabarinus, the 

 red species of temperate regions, but typically it is thinner and smoother 

 and I think cinnabarinus is never stalked. There is no other bright 

 red species of the tropical world that is likely to be confused with 

 Polystictus sanguineus. Bleached specimens are sometimes collected 

 that have lost all their red color. 



CINNABARINUS. The red species of the temperate world, 

 very similar to the above but thicker and not so brightly colored. 

 It rarely if ever has a distinct stalk, hence does not belong in this 

 section, but we so place it from its evident close relation to the pre- 

 ceding. While not stipitate, it is attached by a reduced base, rarely 

 dimidiate, hence it is related even in its attachment to the stipitate 

 species. Polystictus cinnabarinus is rather rare in Europe, usually on 

 birch, very common in America and favors especially cherry and 

 beech. While ordinarily easily distinguished from the southern species, 

 sanguineus, specimens occur in intermediate territory that are hard to 

 refer. 



(Miniatus of Java from its shape might be sought in this section The brittle, caseous flesh so closely 

 allies it to sulphureus that we place it in that section.)
