DUBLIN NATURALISTS FIELD CLUB. 



OcToBKR 24. — Excursion to Cruagh Wood.— About twenty 

 members and visitors left Terenure at 2.0 on cars and bicycles for Rock- 

 brook, from whence they walked to Cruagh Wood. Here the conductor 

 (D. Houston, F.L-S.) collected the party and gave an interesting 

 account of the structure of the different types of Fungi and distributed 

 an illustrated list of those likely to be found in the locality. The Club 

 had also the advantage of the presence of Dr. K. J. M'Weeue}-, whose 

 knowledge of the specific differences of most of the Fungi collected, 

 added greatly to the interest. A considerable number of the larger 

 forms of Fungi were collected, and at dusk the members returned to 

 town after a most interesting outing. 



NOTES. 



BOTANY. 



Barbula Hornschuchiana in Counties Down and Armagh. 



Often looked for, as a moss that might reasonably enough be expected 

 in County Down, Barbula Hornschuchiana has at length been detected 

 not only there, but also in the conterminous County of Armagh. In the 

 former county it occurs— with immature fruit in November— scattered 

 amongst congeneric and other small mosses on garden paths at Lenaderg, 

 and in the latter on stones at Drumlin. Widely distributed, though not 

 by any means common, in Great Britain, it is remarkably rare in Ireland, 

 having previously been recorded from only two localities :—Inchiquin, 

 County Cork (Carroll), and walls of Carrickfergus Castle, County Antrim 

 (Moore).

Archidium alternifolium in County Down. — A correction. 



The moss from County Down adjudged to be Archidium alter nifoliuui 

 and recorded as such {Irish Naturalist, 1907, vol. xvi., p. 215), has since 

 been found not to belong there. The record must therefore be with- 

 drawn. From their examination of further specimens, recently gathered, 

 Mr. H. N. Dixon and Mr. W. E. Nicholson agree in the opinion that the 

 plant is probably some species of Dicranella, that opinion being sup- 

 ported by the presence of radicular tubercles, but, for the present, it is 

 indeterminable. It has appeared for several consecutive years on culti- 

 vated soil, and hitherto has been always sterile. It will, however, be 

 kept under observation in the hope that more light may yet be given.
