Type Studies in the Hydnaceae—VI. The Genera Creolophus, Echinodontium, Gloiodon, and Hydnodon

Climacodon P. Karsten, Rev. Myc. 31: 20. I88I. The genus Creolophus Karst. was established on Hydnum corrugatum Fr. as the type. No type specimen of this species was found at Upsala bult 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 representatives of the species. They do not appear to be generically different from H. septentrionale Fr., having much the same form, color, and fleshy or subfleshy substance. The species has not yet been positively recognized 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.
