Poli/porus.] FUNGI. 141 



species is hard and altogether different from the foregoing. It is by no 

 means confined to willows. The scent is very strong, like that of 

 aniseed in the fresh plant ; Greville, however, describes it as almost 

 scentless. I have not here attempted to assign accurately the synonyms 

 of the earlier English writers on Fungi. Purton's B. salicinus appears 

 to be the present species. 



22. P. vehdmits, Pers. (velvety Pohjporus) ; imbricated whitish 

 or brownish- grey, pileiis between corky and coriaceous tliin 

 velvety obscurely zoned, pores exceedingly short minute round 

 whitish. Fr. Syst. Myc. v. 1. p. 368. Grev. Ft. Ed. p, 401. 

 - — B, velutimis, Pers. Sy7i. p. 539. 



On trunks and stumps of trees generally close to the ground. Spring 

 to autumn. I^ot rare about Edinburgh. Dr. Greville. — More or less 

 imbricated. Pileus 2 — 3 inches broad, velvety, undulated, obscurely 

 zoned, between corky and leathery, margin thinner than in the follow- 

 ing species, shrinking and curling inwards when dried ; colour various, 

 whitish with a cottony margin, yellowish-fuscous, or brownish-grey ; 

 the latter is most common. Pores whitish or yellowish, minute, round, 

 very short, often disappearing towards the margin. The whole of the 

 above account is taken, from Dr. Greville, who is the only authority for 

 the species. 



23. P. versicolor, L. (^party-coloured Pohjporus^ ; pilei cori- 

 aceous villous adorned with various coloured zones more or 

 less shaded with blue, pores round white. Fr. Syst. Myc. v. 1.

On trunks of trees, posts, sticks, &c. : extremely common. — Variable ; 

 sometimes quite resupinate, or with the niargin rcflcxed ; more generally 

 dimidiate and densely imbricated, occasionally spuriously stipitute, more 

 or less lobed, villous, marked with regular concentric smooth shining 

 zones of various colours, sometimes entirely white, and not unfrcquently 

 the whole surface is villous and the zoiues mere depressions. 



24. P, pallescens, Fr. (pale Poly poms) ; pilei subcoriaceous 

 subpulverulent zoneless pale-ochre, pores unequal. Fr. Syst. 

 Myc. V. \.ji. S()9.—B. pcllrpor?ts, Sow. t. 230. 



On old stiMups : not common. Clifton, Notts, llcv. M. J. Bcrhelcy. 

 — Thin iml)ricated, 2—3 inches or more broad, with scarcely any trace 

 of zones, more or less tubercuhited, j)orcs minute, many quite super- 

 ficial, but towards the base a line or more ilee[i. l^oth the original 

 specimens of Sowerby and those collected by myself have a pulverulent 

 aj)pearance arising from a very minute down.
