Glare Island Survey— Fungi. 13 13 



my visits to Westport were made after an exceptionally dry time. In 1910 

 the months of September and October were the driest that had been known 

 there for many years. The general prevailing dampness of the atmosphere is so 

 great that all tree-stumps are quickly covered over with a dense felt of 

 mosses; and dead wood, fallen branches, fungi, and leaves rapidly decay and 

 produce many ascophores of Chlorosplenium aeruginositm (Oed.) de Not, Coryne 

 sarcoides (Jaeq.), Xylaria hypoxylon (Linn.) Grev., and Ustulina vulgaris i-Tul., 

 whilst the old hollow trunks of Beech and other trees are carbonized and 

 stained black by the mycelia of these two last species. Few specimens could 

 be found in the woods facing north, and hardly any dead leaves remained 

 beneath the Holly trees. In 1911 still drier conditions had prevailed, and 

 hardly any rain had fallen at Westport during the months of May, June, July, 

 and August, and only a small quantity towards the latter half of September. 

 We found, however, a good growth of fungi in Brackloon woods, the Old 

 Deer-park wood at Mount Browne, Knocknanny Wood, and the pine wood 

 on Achill Island, but scarcely any in the woods adjoining the Westport 

 House demesne, Prospect House woods, Belclare, and Cloonagh wood. In 

 1898 my wife and I spent a fortnight in the south-west of Ireland at 

 Glengariff and Killarney, and we were then, as on the recent visit, struck 

 by the numerous species of Cortinarius that were to be found there and the 

 typical mode of their growth, which made it much easier to determine the 

 species of this genus than is generally the case elsewhere. On both of my 

 visits Mr. B. Lloyd Praeger kindly assisted in the collection of specimens 

 during the course of two week-ends. We are also indebted to Miss A. 

 Lorrain Smith, F.L.S., Miss Gulielma Lister, F.L.S., Miss E. M. Wakefield, 

 Mr. A. D. Cotton, F.L.S., Mr. J. Adams, m.a., and Mr. J. Barnsbottom, b.a., for 

 kind help in the determination and collection of specimens. In 1910 

 J. Adams and G. H. Pethybridge published in the Proceedings of the Boyal 

 Irish Academy, vol. xxviii., section B, No. 4, " A Census Catalogue of Irish 

 Fungi," and they there set out a list of Irish fungi published by various 

 writers (of very varying reliability in their determinations) up to that date. 

 This' is the only general guide that we possess as to the occurrence of fungi 

 in Ireland. The appended list includes 667 species and varieties, of which 

 number over 232 are additions to the Irish fungus flora, and almost all 

 of them are first records for the sub-province of Mayo, C2 of the census 

 catalogue list. Five are additions to the British fungus flora, namely, 

 tjrceoldla incaratina (Quel.) Boud, Gloniopsis Mulleri (Duby) Sacc, Anthosloma 

 saprophilum E. & E., Diaporthe exasperans Nke., and Coprinus Friesii Quel., 

 and one is new to science — Hygrophorus squamuloms Bea. For the benefit of 

 future workers in the district I give the distribution of the species in detail.
