dish-grey, here and there ferruginous ; substance rhubarb- 

 coloured ; pores small, greyish-umber. Pilei ^ — | of an inch 

 thick, 4 inches broad, 2^ inches long, suberoso-coriaceous, 

 wrinkled, coarsely scabrous, in parts as if overgrown with a 

 small Isidium, reddish-grey ; margin paler ; extreme margin 

 and base sometimes ferruginous. 



New Orleans. I have drawn up a character for P. gilvus, 

 from an original specimen of Schweinitz, as Fries^s specimens 

 appear to have been very imperfect. The New Orleans plant 

 is certainly the same as the Pennsylvanian, but it acquires a 

 much larger size. 



32. P. {Apus, Bienn.) calvescenSy Berk. Fawn-coloured, 

 rather thin, hard, suberoso-coriaceous. Pileus dimidiate, sub- 

 imbricate, rather rugged, older part naked ; border bright 

 zoned, beautifully velvety. Hymenium uneven ; pores rather 

 minute, angular, dissepiments thin ; margin abruptly barren. 



New Orleans. Pileus 1^ inch long, 2^ inches broad. Al- 

 lied to the foregoing.

 rica. Mr. Drummond in Capt. Franklin's expedition. 



36. P. {Apus. Ann. Suberosi) obtusus, Berk. Pileus thick, 

 pulvinate, fleshy, spongy, soft, tomentose, white ; margin very 

 obtuse; pores unequal, rather large, irregular, subgyrose, 

 tawny when dry. Pol. Drummondii, Kl. MSS. in Hook. Herb. 

 Pileus 4 — 6 inches across, 2 inches thick at the base, minutely 

 tomentose; substance soft but tough, white. Hymenium 

 rather convex; dissepiments jagged, often projecting like 

 teeth ; pores very unequal, f line broad, 1 inch deep. Allied 

 to Pol. suaveolenSy but the habit is diiferent, and the pores 

 much larger and more irregular, and the substance denser. 



North America. Mr. Drummond. 



37. P. {Apus, Ann. Sub.) leoninus, Kl. 1. c. p. 486. Pileus 

 effuso-reflexed, fleshy, spongy, fibroso-hairy, tawny; pores 

 rather large, deeply jagged and sinuated, dissepiments deeply 

 toothed. Pileus effused for several inches, zoneless^ clothed
