On willow, cherry, plum-trees, &c. : very common. — Much harder 

 and of slower growth than the preceding and much less fit for 

 making tinder. The pileus is al.so narrower and very much thicker, 

 resembling a horse's hoof; the margin obtuse and the mass of tubes, in 

 general, either plane or very convex. Occasionally, w hen growing on 

 the under side of a branch, the pileus is very imperfectly developed. 



36. P. Rihis, Schum. (^Currant-bush Polgporus) ; tawny- 

 ferruginous, pileus rather thin flattened and somewhat velvety, 

 pores short minute equal. Fr. Syst. Mt^c. v. I. p. 375. Part,

On the root of the red Currant and Gooseberry : very common.— 

 Imbricated, 3 inches or more broad, thin, zoned and velvety, of a 

 rather rich tawny-brown, the margin paler and brighter. Substance 

 soft, silky, fit for making tinder. Pores short, larger than in the fore- 

 going species, brownish-grey. 



37. P. cofichdlus, Pers. (Shell-lilie Polyporus) ; hard, i)ileus 

 rather thin effuso-reflexed imbricato-sulcate yellowish-brown, 

 pores small cinnamon. Fr. Syst. Myc. v. 1. p. 376. — Bol, 

 conchatus^ Pers. Syn.p. 633. — B. impuber, Sow! t. 195. 



On Sallow and Sulix alba; not nnconnnon. — This appears to be the 

 B. impuber, Sotv., original specimens of which are now before n)e ; 

 most certainly they arc not referable to P. cuticuluris. The s|)ecimens 

 from which the smaller figures were drawn, are not distinguishable fi-om 

 P. lUbis ; and it is probable that P. fcrruyinosus was also in view, 

 abundant s[)ecimens of which remain in Mr. JSowerby's collection, though 

 he has given no express figure of it. The specimen, from which the 

 larger figure was taken, seems to be the same w ith P. cunclidtus, w hich 

 occurs not uiinequently on pollard sallows. The principal distinction 

 between this and the foregoing species a|)pcars to reside in the harder 

 substance and smoother pileus. It varies in the degree in wiiich its 

 surface is grooved. Sowcrby's larger specimen is very little grooved 

 and coarsely nodulose. 



38. P. unddtusy Pers. {wavy Polyporus) ; broadly effused 

 pale cinnamon broken up into wave- like elongated dopendcnt 

 tubercles, pores minute. Pers. Myc. Eur. v. 2. />. 90. t. 16. f,

On fir stun)ps. Clifton, Notts. Pt v. M. J. Bcrlulty.—T\\e peculiar 

 stalactitic form of the present species certainly arises from its growing 

 in a particular position. The whole efliised or more i)roj)erly dccnnen't 

 mass is broken uj), as it were, into niinnte elongated ungulate depen- 

 dent pilei, the surface of whicii is slightly zoned and striated bv an 

 cflbrt of nature to form tubes uj)on it. Tlie substance is rather hard
