From a purely botanical aspect the acceptance of Mr. 

 Raid's theory presents many difficulties. When we try to 

 apply it to the origin ol the Irish fauna, even the migratory 

 birds, in whose efficacy as distributing agents Mr. Reid 

 places so much reliance, cannot help us. It is preferable 

 to approach the problem both from a botanical and a 

 zoological point of view. Only in such a manner can 

 important questions of that kind be adequateh^ discussed.

IRISH FUNGI. 



BY W. B. GROVE, M.A. 



A short time ago Mr. J. Adams, of the Royal College of 

 Science, sent me a large series of Fungi (chiefly Uredineae) 

 from various parts of Ireland. Amongst them, I find the

 recorded before for that country. Those marked with a f 

 are apparently new to the British Isles.
