No. 288. — Lecidea ? aurantiaca (Leight.). Sheepwalk, Armagh. T.J- 

 Mr. Carroll thinks may be Callopisma 

 ochraceum (Mudd), which he considers a 

 var. of Lecanora aurantiaca. This plant 

 belongs to Massalongo's Blastiniospori. 

 It is a Lecidea from the beginning. - 



*No. 174. — Lecidea bacillifera (Nyl.). Sheepwalk, mouth of the cave. 

 T. J. 



Ny lander's habitat is on wood, and this is 

 on stone.* I do not attach any value 

 to that ; but the thallus is different ; the 

 colour of the apothecia different. Iodine 

 causes blue, which partially becomes 

 sordid ; and the plant must be consi- 

 dered a form of Lecidea bacillifera 

 (Nyl.). The spores of this plant are 

 3-septate, and measure -00055" to 

 •0007" by -00008" to -0001". Paraphy- 

 ses, subconglutinate ; hypothecium pale. 



Nylander has seen this plant, and has 

 named it. 



No. 187. — Lecidea calcarea {Weiss). Near Ballymoon, Co. Carlow. 

 T.J. 

 This Lecidea has been named L. umbili- 

 cata (Ram.). P armaria nigra also occurs. 



*No. 168. — Lecidea calcivora (Nyl.), Lecidea immersa (Sm.). Sheep- 

 walk, Armagh. T. J. 



No. 276. — Lecidea (Placodium) canescens (Ack). Near Cork. T. J. 

 Fruited. A common plant, but rarely 

 fruited in Ireland. 



No. 177.— Lecidea chalybeia (Borr.) Sheepwalk, Armagb. T. J. 



No. 10. — Lecidea coniops (Wahlb.). Barclay's Rock, Co. Down. T.J. 



No. 21. — Lecidea contigua (Fr.). Woburn, Co. Down. T.J. 



No. 182.— Mount Leinster. T. J. 

 An old plant. 



*No. 71. — Lecidea disciformis (Fr.). Howth, close to the sea. T. J. 

 No. 104. — Curraghmore. T. J. 

 No. 104 corresponds with L. disciformis in 

 essentials ; but it is not the usual ap- 

 pearance of the plant ; both forms of 

 fructification.
