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,

 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.) calvescens, Berk. Fawn-coloured, 

 father 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, ^ hne 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.
