JONES — ON THE IRISH LICHENS. 123 



No. 107. — Lecanora ventosa (Ach.). Croaghan, Co. Donegal. T. J. 

 Both forms of fructification. 



No. 321. — Lecanora ? Tower Hill, Curraghmore. T.J. 



See my 1571. 

 Perhaps, though varying in colour of Apo- 

 thecium, not distinct from No. 316, ante. 



Lecidea {Ach.). 

 No. 265. — Lecidea abietina (Nyl.). Curraghmore. T. J. 



Showing second form of fructification 

 Though this second form of fructification 

 is plentiful at Curraghmore, apothecia 

 are not formed ; so large are the sper- 

 matia, that, unless both forms are seen 

 together, one could scarcely believe they 

 belonged to one and the same plant. 

 This is Pyrenothea of authors. 



No. 105. — Lecidea albo-atra (Hoffm.). Demesne, Armagh, on young 



trees. T. J. 

 No. 3. — Lecidea aromatica (Turn.). Lime-capped wall, "Woburn, Co. 

 Down. T. J. 

 No. 128.— Sheep walk, Armagh. T. J. 

 In the latter locality L. aromatica places 

 itself on the thallus of Collema nigrum 

 (Huds.). 



*No. 87. — Lecidea atro-grisea (Delise.). Demesne, Armagh. T. J. 



No. 114 & 11. — Demesne, Armagh. T. J. 



No. 114 is taken as a form, on account 

 of the colour of its young apothecia ; it 

 always remains unlike in aspect to 

 No. 87. See also No. 117. 



No. 117. — Demesne, Armagh. T. J. 

 *No. 185. — Lecidea atro-sanguinea (Hoffm.). Curraghmore. T. J. 

 No. 4. — Lecidea aurantiaca (Light/.). Lime-capped walls, Woburn, 

 Co. Down; and sheepwalk, Armagh. 

 T.J. 



Mr. Carroll thinks this is a form ; the ty- 

 pical plant is doubtless on trees ; but in 

 essentials T do not find any tangible dif- 

 ference. The paraphyses are septate, 

 sparingly branched, sometimes com- 

 pound — thatis, many-headed; in general 

 the apothecium is at first enclosed ; this 

 is not the case here.
