 Rehm in placing part of the Saccardian species of Gloniella 

 in the Hypodermataceae under the name Gloniella and part 

 in the Hysteriaceae under the new generic name Hystero- 

 glonium. This disposition of the species is probably well 

 founded but the original description of Gloniella clearly

 and not of the Hypodermataceae. The name should there- 

 fore be retained for those hysteriaceous species that were 

 first included in it. It is in this sense that the name is used 

 above since our species clearly belongs in the Hysteriaceae.
