IRISH SOCIETIES. 



DUBLIN MICROSCOPICAL CLUB. 



January 12. — The Ciwh met at Leinster House. Dr. G. H. Pethy- 

 BRiDGE exhibited sections of the needles of Finns excelsa,' from a nursery 

 in Wexford, attacked by the parasitic fungus Lophodcinniiiiii lineaiuni. 

 The attack was noticed in 1919, and the fungus causing it was described 

 as a new species by Miss A, Lorrain Smith and iNIr. J. Kamsbottom (to 

 whom specimens for identification had been forwarded by the exhibitor) 

 in Trans. BHiish Mycological Soc, vi., .|, p. 3O3, 1920. 



Sir F. W. Moore exhibited Chvysomyxa abiciis in its winter stage. \i 

 former meeting exhibitor had shown specimens in tlie summer stage. The 

 latter came from Co. Wicklow, the specimens now shown were obtained 

 in Co. Dublin. It has also been found in Co. Meath. 



H. A. Lafferty exhibited preparations illustrating the effect of the 

 " browning " fungus on flax fibres. The middle lamella of the cells was 

 converted into a substance which, when tested micrcxhemically, gave the 

 characteristic reactions of lignin. 



February 9. — The Club met at Leinster Mouse. Paul A. Murphy 

 exhibited a preparation of portion of the leaf of a potato plant affected 

 with leaf roll, and a corresponding portion of a healthy plant. The cause 

 of the leaf roll is unknown, but the disease brings about a marked retarda- 

 tion in the rate at which starch is removed from the leaves. The most 

 outstanding difference, therefore, between diseased and healthy leaves is 

 the presence of abundant starch in the morning hours in the former, and 

 its practical absence in the latter.
