A true parasite, especially attacking Fagus silvatica. 



Seems to be rather unknown abroad. Correct specimens are contai- 

 ned in Allescher &. Schnabl's Exsiccat. no 228. Pileus hard and woody, 

 perennial, composed of many strata of tubes, cuticle thick, hard, resi- 

 nous. Flesch rather soft, floccose, foxy-rust-coloured, tubers short, 

 ferruginous, pores very small, of a distinct, sulphur-red colour. Spores 

 ovoid, brown, 11—15 f^ X 7—9 f^. The conidia (Sepedonium fuscum 

 Rostrup 88 c'^) are brown, granular, petiolate, 11—13 l^ X 8—9 t^, to 

 be found on the upper surface of the pileus. The sporophores of 

 Polyporus vegetus become very large. The largest specimens found 

 in Denmark are 60 cm X 30 cm across and 15 cm in height, con- 

 sisting of 15 strata. In several places in his publications Rostrup has 

 been mistaken in indicating this fungus by the name of Polyporus 

 resinosus (R 69 5^ 80 a^«^ 88 c ^^ Lange 87).
