_General Information_: It is often associated with nodulose masses of fungal tissue which are covered in small poroid areas and are very confusing when found by the beginner; they are simply growth-forms of _Coriolus versicolor_; such forms are frequently found on old house-timbers exposed to the weather, particularly window frames where it forms a distinct rot. Its flesh consists of thin-walled hyphae and binding hyphae as in _Polyporus squamosus_ as well as an additional thick-walled type called skeletal hyphae. It would appear that several polypores are capable of producing the amorphous growths mentioned above, some of which contain hyphal fragments called conidia. The bands of colour on the cap of the ‘many zoned polypore’ are retained after drying and from a group of fruit-bodies the most attractively zoned can be selected, mounted on small pieces of wood or cardboard and fitted at the back with a pin. Such preparations make very attractive brooches and have been used even by modern designers to contrast with their fashion creations. There are many pale tubed polypores growing on wood. _Daedalea quercina_ Fries ‘Mazegill’, grows on oak and has irregular maze-like pores; _Lenzites betulina_ (Fries) Fries, grows on birch, has tough plates which resemble the gills of an agaric. _Datronia mollis_ (Fries) Donk forms thick spreading resupinate patches on beech, sometimes with irregular dark brown caps formed by the upturned margin. Several species of _Tyromyces_ occur in Britain and are characterised by their white pores and tubes and the white or pale-coloured caps. _Bjerkandera adusta_ (Fries) Karsten has a grey pore-surface and is also frequently found on beech. _Illustrations_: F 44a; LH 69; NB 117³; WD 51². ~Ganoderma europaeum~ Steyaert Common ganoderma _Cap_: 100-350 mm. _Stem_: absent. _Description_: Plate 47. Cap: bracket-shaped, rather flat at margin but humpy and irregular about the middle, frequently concentrically zoned, smooth and only slightly shiny; its margin is whitish or pale greyish. Tubes: red-brown or cinnamon-brown, obscurely layered and with small, white pores flushed with pale cinnamon-brown, but deep red-brown when rubbed or with age. Flesh: with a fragrant smell, deep red brown and felty-fibrous. Spore-print: dark cinnamon-brown. Spores: long, oval with truncate apex, smooth, but reticulate on the inner surface of the inner wall giving the spores a patterned appearance when seen under the microscope; 10-11 × 6-7 µm in size. _Habitat_ & _Distribution_: This fungus is common on various trees, especially beech and can be found throughout the year.
