1909- M'Ardle. — Musclnecs from Fcn/ianag/i and Donegal. 145 



cliffs I found Orthothecium i)iiricaiii/n, a rare moss, conspicuous 

 on account of the yellowish-green silky tufts ; it may be over- 

 looked for Hypnuni cupycssifo}mc var. resnpiiiatuni, but it is 

 more highly coloured and grows on rocks. Though I searched 

 the neighbourhood carefully, I found it only in one place ; 

 hitherto its range has been confined to North Kerry, Sligo 

 and West Donegal. 



One wet morning I got a boat and rowed about a mile on 

 Lough Erne to Heron Island, which is probably the smallest 

 which dot the extensive lough near Church Hill. I chose 

 this island as it was near the shore ; the boat was a very frail 

 structure, and had been exposed to the sun and weather for a 

 long time. Some grass and trees of Alder and Birch grew 

 among the rocks. The liverworts I gathered were Melzgeria 

 fiifcata and Radula coniplanata on the trees, Aneiua multifida 

 and Blasia pusilla among the wet rocks Mosses were better 

 represented, and I gathered seventeen species. 



On this trip I add eighteen species and five varieties to i\\\ 

 former list^ of Fermanagh mo.«^ses. Among the liverworts 

 collected I add the following to the previous list : — Cephalozia 

 airvifo/ia, Scapania mnbrosa., Jtuigei viania crcnulata., f. barbata, 

 Nardia scalaris^ Blasia pnsilla. Other species included below 

 which were in former list are from a locality remote from 

 where the}- were previously collected, and much yet remains 

 to be done in this interesting county. 



I spent a few days on Slieve League, Co. Donegal, searching 

 for mosses and liverworts. I followed a stream to near the 

 summit, which rises to 1,972 feet. At a small waterfall 

 Eurhyyichiuni ruscifornic and the variety atlanticuni flourished 

 within the spray — very fine specimens of the latter, similar to 

 those I found some }"ears ago on a steep rocky bank near the 

 sea on the shore of Dingle Bay, Co. Kerry. Here also I 

 gathered a rare liverwort, Scapania subalpina, a very distinct 

 plant. On decayed wood with Frullania, Lophocolea hctero- 

 phylla grew sparingly ; it has a remarkable aromatic smell. 

 Nardia obovata was on the rocky bank of a stream ; I have 

 some forms of this interesting plant which very closely asso- 

 ciate it with N. hyalina, and I would be inclined to sa}' they 

 are both forms of one species. On wet rocks, Marsitpella
