The Characeae, the most highly organised of freshwater algas, are listed 

 in the Irish Naturalist (1895), by the brothers Grove, and the writer pub- 

 lished in the same periodical a general account of the group and a key for 

 the recognition of the species found in Ireland. 



In spite of the economic importance of the fungi as causes of some very 

 'destructive diseases, and of their fascination as a field study, no group has 

 received less attention in Ireland. This neglect is partly due to the great 

 •difficulty in preserving the larger forms for reference and examination 

 beyond a few hours after collection, and to the scarcity of botanists in 

 Ireland for the investigation of the microscopic forms. The first serious 

 attempt to prepare a comprehensive list of Irish fungi was made by Green- 

 wood Pim, in the Guide Book of the British Association Meeting in Dublin 

 in 1878, where 478 species are recorded, (See also Procs. R.D.S., 1878), fol- 

 lowed by a Supplement comprising 60 species, in the Procs. RJ.A., in 1883. 

 In 1893, Greenwood Pim and Prof. E. J. M'Weeney, M.D., published a 

 paper in the Iris/t Naturalist (vol. 2, pp. 245-257), in which 270 additional 

 species are recorded. In 1898 these lists were consolidated and added to, 

 giving 830 species, to serve as a guide to the British Mycological 

 Society, which, during its week's visit to Dubhn, added in their list of 430 

 species {Irish Naturalist, vol. 7, p. 286), 160 species to the previous records. 

 This Society made the Museum its headquarters and gave a large number 

 of specimens to it. Thus, for the Counties bf Dublin and Wicklow, about 

 1,000 species of fungi have been observed, some new to science, or to the 

 British Flora, or very rare in Great Britain. 



The Rev. H. W. Lett, M.A., gives a list of some 580 names in the Procs. 

 Belfast Field Club for the year 1886, of species found in Down, Antrim, 

 Armagh, and Cavan. 



Greenwood Pim published a preliminary note on the fungi of Glengarriff 

 and Killarney in the Procs. RJ.A., 1885. 



The rest of Ireland is practically a blank so far as our knowledge of 

 systematic mycology is concerned, and a rich harvest awaits the fungologist 

 who will devote himself to the investigation of the fungi of Counties Cork, 

 Kerry, of Connemara, and other regions in Ireland.

 of fungi in Ireland : — -
