and consists almost entirely of tubes which are larger than those of P. 

 igniarius, and form either a plane or obtuse mass. Whatever the per- 

 fect form of this species may be, it is certainly very different from any 

 other known British species.

39. P.ferruginosus, Schrad. (^small ferrvginoiis Polyporus) ; 

 effused rather thick tawny-cinnamon, browner when old, pores 

 subrotund unequal. Fr. Syst. Myc. v. }. p. 378. Book. Fl,

On rotten branches lying on the ground; not uncommon — At first 

 appearing under the form of a confervoid stratum which gradually 

 thickens and acquires pores in the centre ; generally wholly resupinate, 

 but occasionally slightly reflexed, in which case it is roughish and tomen- 

 tose. Fores minute, roundish, unequal. Specimens sometimes occur 

 many inches in length and, in parts, ^ of an inch thick, from several 

 individuals having become confluent. 



40. P. incarncUus, Pers. {orange-fesh Polyporus) ; effused 

 coriaceous very thin submarginate, pores orange-flesh colour 

 minute round suboblique. Fr. Syst. Myc. v. 1. p. 379. EL 

 V. 1. p. 119. Grev. Fl. Ed. p. 403. — Pol. incarnatus, Pers. 

 Syn. p. 546. 



On trunks of fir-trees, especially when in a state of decay. Drum- 

 shoreland Muir, near Edinburgh ; Greville. — " Effused, irregular, thin, 

 coriaceous, marginate or immarginate ; margin white, cottony, rather 

 thick as if there was a tendency to become reflexed. Pores minute, 

 very short, round, subequal, straight or obh"que, of a fine flesh colour 

 approaching in some cases to orange. Sometimes small cottony pro- 

 tuberances occur amongst the pores, which have the appearance of small 

 pilei with tubes underneath." Grev. I. c. 



41. P. medidla pdnis, Jacq. (crtimb of Bread Polyporus); 

 effused somewhat wavy hard smooth dry white, pores not 

 minute. Fr. Syst. Mijc. v. \. p. 380. Grev. Fl. Ed. p. 402.

On decaying branches and trunks of trees : not common. Dundas 

 Hill, near Edinburgh, Br. Greville.—" Effused, white, becoming yel- 

 lowish in age, roundish, tolerably defined, dry, thickish, following in 

 some degree the inequalities of the wood. Pores elongated, roundish, 

 straight or oblique, according to situation. Flesh almost none." Grei;, 

 I. c. I forbear quoting the synonyms of the earlier English authors, 

 as scarcely any species is involved in so much confusion as the present, 

 though itis very distinct, and if Jacquin's figure had been attended to, 

 need not have been misunderstood. 



42. P. vulgaris, P. (common resupinate Polyporus) ; broadly 

 effused thin dry smooth wliite, pores minute subequal. Fr,
