PUCCINIA BOREALIS Juel. 
The excidial stage of Puccinia borealis on Thalictrum alpinum 
L. was first described by Greville in 1823 in _ Scottish Crypto- 
gamic Flora as Aicidium Thalictri. He states “the specimens - 
were discovered by Mr. Patterson on Ben Voirlih i in one o 
- Hooker's ogre in 1821: since which time I have 
received a specimen from Arnott gathered Py McRitchie i in the 
Highlands.” Guoville’s s record appeared in several of the older 
works on the British fungi; Berkeley fnatided | it in his Outlines 
of Fungology rag Cooke, ft naa — of the British 
Afcidiacet in 1864, described i necommon in Scotland, 
and it is referred to 4 his Hasibak of British Fungi (1871) as 
Ajcidium Ranunculacearum yar. Thalictri Grey. It is omitted,
