The authorities given for the species taken from Lister's Myce- 

 tozoa will probably be found to disagree in many cases with those 

 given by other writers. In his citations he gives as the author of the 

 name the one who first used the special combination adopted. Take 

 for example Enteridium rozeanum Wing. The specific name was first 

 used by Rostafinski in 1876, while the combination quoted above was 

 used in 1880 by Wingate. The proper and now generally accepted 

 method of citing authorities would then in this case be Enteridiu?n 

 rozeanum (Rost.) Wing.
