МВ. W. WEST : ECOLOGICAL NOTES. 75 
Further on towards the outlet of the Loch, many of the trees bore a great 
abundance of large specimens of Ricasolia amplissima with its attendant 
Dendriscocaulon bolacinum, and a still greater quantity of Aicasolia lrtevirens 
occurred also on the trunks, but the former was most abundant in the more 
exposed situations, facing seawards. I have noticed this elsewhere, as in 
Cantyre, Moidart, &с. А number of trees on the eastern side of the Loch 
were practically covered with Stereodon cupressiformis var. filiformis with 
sporophytes in abundance, and creeping over it in very large patches were 
Lobaria Pulmonaria with abundant apothecia and Lobarina scrobiculata. 
Some Ash trees, about 60 centimetres in diameter, were examined in Glen 
Falloch ; they were found to vary considerably, under apparently similar 
conditions, One set averaged: /sothecium myosuroides (25), mostly towards 
base, Stereodon cupressiformis var. filiformis (20), Metzgeria furcata (6), 
Stictina limbata and S. fuliginosa (4), Cladonia squamosa (2), the rest sub- 
bareness. Another set had :—Stereodon cupressiformis var. jiliformis (20), 
Metzgeria furcata (30), mostly on shadiest side, Frullania Tamarisei (20) ; 
the latter seemed to have taken the place of the /sothecium though it was not 
near the base, the Stereodon clothing that part. 
OBSERVATIONS IN IRELAND. 
At Muckross, Kerry (rainfall about 64 inches, rainy days about 225), near 
the side of the road, some Elms and Limes which were some distance apart 
were examined; the moss which almost covered the windward side was 
Camptothecium sericeum ; associated with it were Frullania dilatata, Collema 
flaccidum, Acrocordia gemmata, and a small Leptogium on the moss, 
In the woods adjoining, the species of trees varied much in different parts, 
as many have been planted. Some of the more natural portions examined 
consisted of Oak, Birch, and Holly, with some Rowan, Crab, and Arbutus. 
Honeysuckle and Ivy were frequent. The Oaks in this part were well 
covered with Zsothecium myosuroides (60), Ricasolia letevirens (5), Thuidium 
tamariscinum (2), with a little Stictina limbata and Dicranum scoparium, the 
rest was sub-bareness. Other Oaks nearer the large lake, subject to the 
direct drive of the wind from the hills, had a different epiphytic flora, 
Lobaria pulmonaria was abundant with plenty of Pannaria rubiginosa and 
its variety cæruleo-badia. Coecocarpia plumbea was much less abundant. 
Stereodon cupressiformis var. and Metzgeria furcata also occurred among the 
lichens. Where there was a fair amount of wind-drive in another part of 
the wood, the Oaks were covered all round the base with Eurhynchium 
myosuroides, and bore further up Lobaria pulmonaria (30), Metzgeria Jurcata 
(5), Stereodon cupressijormis (5), Pannaria rubiginosa (2), the rest sub- 
bareness. The Beeches were well clothed with a very varied association оЁ
