SPORES COLORED. 



darker than the context, minute. Setae none. Spores globose, large, 10 mic., 

 pale colored. 



This was named from Java (Zoll. 2058), but the only specimen I have noted is 

 in Patouillard's herbarium. It is rigid and brittle and is not a Polystictus, as com- 

 piled in Saccardo, nor has it any relation to caliginosus as stated. 



SECTION 100. CONTEXT BROWN. SETAE PRESENT. 

 A. Surface tomentose or hispid. 



POLYPORUS HISPIDUS. Pileus sessile, usually large, 8-12 

 inches, and 1-2 inches thick. Surface strongly hirsute, hispid. Flesh 

 at first soft, at length dry and fragile. Tubes small, Y^-Yz mm., and 

 very long, from 2-3 cm. ; fragile when dry, when old, larger and torn. 

 Setae rare and uncertain. Spores abundant, globose, 8-10 mic., deeply 

 colored, smooth. 



This is the largest species in this section, and is said to reach 18 

 inches. It is quite frequent in Europe, growing on frondose wood, 

 apple, ash, and oak in preference. When in its prime it is a striking 

 fungus, bright orange as we remember the only time we ever gathered 

 it. It is described as dull orange or sienna. It turns black in drying 

 and in situ. We are told by Sowerby that it "turns black and rots." 

 The plant has in abundance a yellow coloring matter easily soluble in 

 water. The herbarium sheets are usually stained with it. This color- 

 ing matter could be fixed and used in dyeing were it bright enough or 

 abundant enough to warrant. The director at Kew had some experi- 

 ments made along this line at one time. In the United States, Poly- 

 porus hispidus is rather rare and of a southern range. 



ILLUSTRATIONS. Boudier, t. 158, is the best; Gillet, very good, but rather pale color. 

 Others cited are Bulliard, t. 210 and 493, the latter the better; Bolton, t. 161; Greville, t. 14; Hussey, 

 t. 29 and 31; Sowerby, t. 345; and a number of others in unimportant works. 



SPECIMENS. A number, both from Europe and United States. Our collections are mostly 

 from Florida and New Jersey, and the plant has an evident southern distribution. Lea found it around 

 Cincinnati. We never did.

POLYPORUS CUTICULARIS (Figs. 693 and 694). Pileus ap- 

 planate, dimidiate, imbricate. Surface tomentose with appressed, 

 brown hairs, zonate when young. Context varying from 3-10 mm. 

 thick, hard, fibrillose, ferruginous brown (Sudan brown). Pores small, 

 varying in size, angular or irregular, 5-8 mm. long, with concolorous 

 tissue. Mouths often stuffed or overgrown, when fresh strongly 

 glancing. Setae very scanty, sometimes not found at all, straight. 

 Spores abundant, globose or subglobose, deeply colored, largest 

 7 x 7-8, many smaller, 4-5 x 5-6. 



This grows in the greatest abundance in the United States in the fall of the 

 year, preferably on beech or maple, often densely imbricate over large areas of the 

 log (Fig. 694). It is frequent also in France on beech logs, and on comparison the 

 European plant can not be told from the American. When it first develops, which is 

 always late in the season, it is soft and watery, and the surface is beautifully zoned.
