ADDITIONS TO IRISH ALGAE. LICHENS, AND 

 FUNGI TO THE END OF THE YEAR 1910. 



BY J. ADAMS, M.A. 



In the year 1908 I published " A Synopsis of Irish Algae, 

 Freshwater and Marine" {Proc. Roy. Ir. Acad., vol. 

 xxvii., Sect. B, No. 2). This was followed in 1910 by 

 " A List of Synonyms of Irish Algae with some additional 

 Records and Observations " {Proc. Roy. Ir. Acad., vol. 

 xxviii., Sect. B, No. 5). In 1909 appeared " The 

 Distribution of Lichens in Ireland" {Proc. Roy. Ir. Acad., 

 vol. xxvii.. Sect. B, No. 10) ; and m 1910 " A Census 

 Catalogue of Irish Fungi " {Proc. Roy. Ir. Acad., vol. 

 xxvhi., Sect. B, No. 4), the last being the joint work of 

 Dr. Pcthybridge and myself. I propose in the present 

 short article to include all additional Irish records and 

 papers published on these groups up to the end of the 

 year 19 10. Frc^m that year onwards I hope the workers 

 at the various groups will publish every live years a 

 Supplement in which the facts and figures of each group 

 will be brought up to date. 



I. Algae. 



Freshwater Species. — Nothing additional. 



Marine Species. — The only additional information 

 consists in the record of Codium clongatum and Lcathcsia 

 crispa from Clare Island. Mr. Xotton is of opinion that 

 the former of these species is something quite different, and 

 hopes to publish full particulars about it shortly. Mr. 

 Cotton has also informed me that the Irish record of 

 Lithothamnion Raccmus Fosl. in Batters's Catalogue is an 

 error, and consequently that species must be withdrawn 

 from the Irish lists.
