Aregma, Fr. 



NOTE. The genus Aregma was described by Fries in his Observationes I : 

 225. 1815. The genus Phragmidium was described by Link in Ges. Nat. 

 Freunde Mag. 7 : 30. The date of this volume is given as 1816 on the title- 

 page of the volume and this date has generally been accepted as correct. 

 Fries however in Systema Mycologicum 3 : 495. 1832 makes the statement 

 that Aregma and Phragmidium were published in the same year from which 

 one might infer that that part of volume 7 including Link's paper was issued 

 earlier than 1816. The volume is in four parts of which part one including 

 Phragmidium has the title " Erstes Quartal, Jan., Feb., Marz, 1813." It 

 may therefore be the case that it is to an earlier edition of the Erstes Quartal 

 issued in advance of the volume to which Fries refers. In the Summa, 507. 

 1849 Fries adopted the name Phragmidium including his Aregma. We 

 have referred our species of Aregma to Phragmidium, that name being 

 accepted by most writers.
