Forming small scattered white tufts over the upper side of the leaf. 

 The fertile hyphae seem often quite over-weighted with the large irregularly- 

 shaped heads of mucus containing the relatively large conidia. When free 

 of the mucus, the conidia stand up side by side like so many candles. Part

5. Introduction. 



In the autumn of 1910 I was requested to join in the investigation of the 

 fungi growing in the neighbourhood of Westport in connexion with the 

 Clare Island Survey, but owing to domestic affairs I was unable to proceed 

 there before the 16th November. On my arrival at Westport I found from 

 two to three inches of snow on the ground, although I had been assured 

 before my departure that night frosts were not to be expected in the west of 

 Ireland before Christmas. The snow thawed rapidly, but in some places it 

 remained for a considerable time, especially on the higher ground. During 

 this visit I searched the park and woods adjoining Westport House, Belclare 

 and Prospect House woods, Cloonagh Wood, Derrygorman woods, the Old 

 Deer-park wood, and other woods at Mount Browne ; Knocknanny wood close 

 to Westport railway station ; and the woods near to Kilboyne House, Castlebar. 

 Most of the woods were of a mixed character, consisting of Beech, Oak, Pine, 

 Sycamore, Holly, and Alder. The Kilboyne House woods, some four or five 

 miles south of Castlebar, are made up, almost exclusively, of scrub Hazel, 

 about 8 to 12 feet in height, intermixed with lower Blackthorn bushes, and 

 the intervening ground rough with large stones. These woods proved to be 

 very unproductive and unworthy of another visit. During my stay at 

 Westport, which continued until the 23rd November, about 180 species of 

 fungi were observed, of which nearly thirty were additions to the " Census 

 Catalogue of Irish Fungi." In 1911 I visited Westport in company with my 

 wife and Miss Gulielma Lister, F.L.S., from 3rd to 12th October. In addition 

 to the woods already enumerated, which we revisited, we investigated 

 Brackloon wood on two days, Achill Island, and Croaghpatrick. Brackloon 

 wood is an ideal wood for fungi ; it consists of a mixture of Oak, Beech, Pine, 

 Sycamore, Holly, and Alder, whilst the ground is covered with an abundance 

 of leaf-mould, and many interesting species were observed there. Both of
