HoKizoN. — Upper Cretaceous (Atane Beds). 



LocALiTr. — Greenland. 



Type. — Heer's specimen in University Geological Museum, 

 Copenhagen. 



The twig on which tl\p so-called fungus was detected by 

 Heer (1882) appears to be that of a dicotyledon, which though 

 it is not described by Heer is very common in the Greenland 

 beds. The one specimen -with the " fungus " which Heer 

 mentions, he supposes to be a gymnosperm ; but even superfi- 

 cially it appears much more like a dicot3'ledonous twig. In 

 Stockholm, in Prof. Nathorst's rich collections of Arctic plant- 

 fossils there are a number of similar stems which all show the 

 small markings Heer took to be a fungus, but which bear the 

 strongest likeness to lenticels. 



Hysterites protogceus, in short, seems to be nothing but normal 

 lenticels on woody twigs. 



Order HYPHOMYCETES.
