 same, but in both the hymenium is minutely velvety or setulose. 

 In the present genus there is an unbroken sequence from the

central-stemmed type, with a more or less funnel-shaped pileus 

 and inferior hymenium, through the lateral-stemmed or flabelli- 

 form, to the effused stage, with a more or less developed free 

 margin, or several free margins spring from the effused and 

 adnate portion in a dimidiate manner ; this last runs by degrees 

 into the lowest stage, where the plant is closely adnate to the 

 substratum by its under surface and having the hymenium upper- 

 most, thus closely agreeing in habit with the normal condition 

 in the genus Corticium, but distinguished by the presence of a 

 zone of closely compacted byphse which directly gives origin to 

 the elements of the hymenial layer; from the underside of this 

 layer a looser felt of hyphae penetrate the substratum 

 Corticium no such intermediate layer exists. Again, in Stereum, 

 as a rule the hymenium does not become cracked when dry as in 

 Corticium, and the margin is rarely indeterminate, but in most 

 adnate forms more or less free and strigose.
