POLYPORKT. 249 



On stumps, brandies, etc. One of the most common spe- 

 cies, and as variable as it is common. Some specimens are 

 perfectly white, others yellowish, others cinereous-blue, etc. 

 Some individuals approach near to P. zonatus, which has not, 

 I believe, been found in this country. It is a far thicker and 

 coarser plant. Sow. t. 367 is probably a pale form of this. 



57. P. abietinus, Fr. ; pileus coriaceous, thin, effuso-re- 

 flexed, villous, obsoletely zoned, cinereous-white; pores un- 

 equal, torn, lilac, at length pale. — Grev. t. 221. 



On trunks of Coniferce. Almost as common as the last in 

 fir-woods, and sometimes very pretty. Extremely variable in 

 form, but always easily recognized. 



58. P. Wynnei, B. and Br. ; confluent, various in form ; pi- 

 leus aduate behind, efiuso-reflexed, then tan-coloured, marked 

 with silky raised lines ; pores small, angular, white. 



Running over twigs, grass, etc. Rare. Cheshire. Coed 



Coch. Pores becoming pallid in drying. This species has 



somewhat the habit of P. amorphus, but is very different in 

 substance. 



5. Resupinate. 

 * Pores coloured. 



59. P. contiguus, Fr. ; effused, firm, at first obscurely cin- 

 namon ; circumference villous or fibrous, then smooth, ferru- 

 ginous ; pores middle-sized, equal, obtuse, entire. 



On rotten wood and sticks. Not common. East Bcrgholt, 

 Dr. Badham. P. cellaris, Desm., is probably the same spe- 

 cies. It has been found at Oswestry by Mr. Salwey. 



GO. P. ferruginosus, Fr. ; effused, firm, tawny, when old 

 ferruginous, bright brown ; circimiference barren; pores elon- 

 gated, roundish, middle-sized, cinnamon. — Grev. t. 155. 



On gate-posts, fallen sticks, etc. Common. IMycclium
