The genus Creolophus Karst, was established on Hydnum cor- 
rugatum Fr. as the type. No type specimen of this species was 
found at Upsala but several specimens in the herbarium collected 
by P. A. Karsten, E. Th. Fries, and Fr. Kjellman in Sweden and 
Finland were referred to this species. All of these agree perfectly 
with Fries’s description and may be regarded as authentic repre- 
sentatives of the species. 
They do not appear to be generically different from H. septen- 
trionale Fr., having much the same form, color, and fleshy or sub- 
fleshy substance. The species has not yet been positively recog- 
nized as an American form. 
Climacodon Karst, was established on Hydnum septentrionale 
Fr. and is, therefore, a metonym of Creolophus. 
We have hitherto included the species of this genus in the genus 
Steccherinum. The peculiar fleshy or subfleshy character of the 
substance of these plants, so strikingly different from the dry and 
tough fibrous character of typical Steccherrinum, has convinced us 
that they should be maintained in a separate genus for which a 
name has already been provided by Prof. Karsten.

There is no type of this species preserved at Upsala, but forms 
of the plant often found on beech in Indiana conform perfectly
