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. ]?r. 



Wholly resupinate, or usually effuso-reflexed ; pileus 

 coarsely strigose, dingy ochraceous, becoming pale and 

 ■greyigE^~in3iitinctly zoned, substance thin and coriaceous ; 

 hymenium 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 with 

 a very narrow free portion. When developed on smaller 

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

 several such arranged in an imbricated fashion. Pileus 

 coatsely velvety or strigose; hymenium usually bright 

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



Var. subcostatum. Karst. 



Hymenium naked, vaguely costate or rugose, yellowish- 

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



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



Certainly not a good species, intermediate forms leading 

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



Var. cristulatum. Quelet. 

 Pileus strigose, grey ; hymenium flesh-colour.
