others evidently parasitic. F. E. Weiss * has recently described a speci- 

 men that he has found on rootlets from the lower coal-measures, which 

 seems to correspond with the Mycorhiza of recent times. In the root or 

 rhizome examined, the fungus mycelium was very evident in the exo- 

 eortex. In the cells of the medio-cortex there were somewhat indefinite 

 masses that recalled the " clumps " characteristic of the Mycorhiza of 

 living plants, but no definite details could be made out. The clumps 

 were connected with the cell-walls by delicate protoplasmic filaments, 

 which were probably contracted hyphae. The whole fungus differs 

 materially from other cases of endophytic fungi observed in fossil 

 plants, and is evidently neither parasitic nor saprophytic on the host- 

 plant. The author has been unable to identify the root ; he therefore 

 gives it the non-committal name of Rhizonium. The fungus he de- 

 signates provisionally as Mycorhizonium.
