1908. Notes, 21 



II. — Whilst it is still possible to study these plants the writer further 

 would wish it known that a Lichen Exchange Club is being formed for 

 the encouragement of the study of lichenology. For many years past 

 these plants have received lit tie attention, and it is thought that a medium 

 for the exchange and naming of critical or little known species would 

 give some impetus to those who already study these plants as well as 

 beginners also. 



Ireland affords many opportunities for the field-botanist interested in 

 cryptogams to study Mosses, Hepatics, and Lichens, and there are a 

 number of Irish species unknown in Kngland or Scotland, whilst as a 

 whole it presents a far better hunting-ground for these plants than most 

 parts of the British Isles. It is desirable,therefore;that the study of lichens 

 be encouraged in Ireland. The writer will be pleased to receive the 

 names and addresses of those desirous of becoming members of the new 

 Club. Communications on this point and as to the extinction of 

 cryptogams in Ireland may be addressed to Ivanhoe, Gwendolen-road, 

 Leicester.
