On the ground. Forming dense tufts 6-10 in. across and 

 2-3 in. high. Substance of pileus thin, crisp and carti- 

 laginous when fresh, and of a beautiful flesh-colour. The 

 dark zones vary much in intensity in different specimens.

Stereum hirsutum. Fr. 



Wholly resupinate, or usually effuso-reflexed ; pileus

 greyish, indistinctly zoned, substance thin and coriaceous ; 

 hj^menium even, glabrous, naked, bright ochraceous or pale

 p. 181. 



On trunks and branches. Very variable in form, when 

 growing on a broad surface often wholly resupinate or wi th 

 a very narrow free portion. When developed on smaller 

 branches there is often a broad, free, refiexed portion, or 

 several such arranged in an imbricated fashion. Pileus 

 coarsely velvety or strigose ; hymenium usually- bright 

 ochraceous, often with varying shades of pin k: or grey.

 white, bright flesh-colour or yellowish-red towards the base. 



Stereum subcostatum, Karsten, Hedwigia, 1881, p. 178. 



Certainly not a good si)ecies, intermediate forms leading 

 up to the typical form of S. hirsutum being not uncommon.
