Examination of the type specimen at Kew shows this to be 

 an immature specimen of some Thelephora. 



55. Stereum, Pers. 



Pileus with a central stem, or dimidiate and imbricated ; pileus 

 silky or strigose ; hymenium smooth ; spores colourless 

 (rarely tinged ^vith colour). 



Stereum, Persoon, Obs. Myc, p. 35. 



The leading features of the present genus are the smooth or 

 glabrous hymenium, and the velvety or strigose pileus. Some 

 species are destructive wound-parasites, attacking forest trees. 



* Pileus supported on a central stem.

White ; pileus funnel-shaped 2-2*5 cm. across, rough with 

 projecting points, but not velvety, margin variously incised ;

On the groimd. Northern Island, New Zealand. Tasmania, 

 Australia, Britain, United States. 



A very beautiful species, snow-white, tinged with pale-buff 

 when old, and of a waxy appearance when fresh ; sometimes 

 with a distinct round stem J in. or more in height, at others 

 several plants grow close together, having their stems more or 

 less confluent at the base. It has no relationship with Clado- 

 derris, as suggested by Fries in Sum. Veg. Scand., p. 332. 



** Pileus (ittached laterally.
