JONES — ON IRISH LICHENS. 281 



by Mr. Pigot at Glengariff, named by Leighton* Opegrapha anomala 

 (Leight.), and subsequently named by Muddf Stenographa anomala 

 (Mudd). Its spores are very similar to those of the plant Mudd inserts 

 as Stenographa anguina (Mont.), = Graphis sophistica (Nyl.). Their 

 spores are also peculiar ; as when solution of iodine is applied to them, 

 they become indigo-blue, whilst the hymenial gelatine is hardly 

 affected. Mr. Carroll has also found Thelotrema subtile, in this collec- 

 tion No. 371, at Lough Inchiquin, county of Kerry. This is only known 

 hitherto as a North American plant. Mr. Carroll has added two other 

 rare Lichens, both new to Ireland — one, Stigmatidium venosum (Borr.) ; 

 the other, Lecidea incompta (Sm.). 



The following is the List of the Lichens now added to the Collec- 

 tion, arranged as before for facility of reference in alphabetical order 

 as regards Genera and Species, respectively. An asterisk (*) indicates 

 species not recorded in Mackay's " Flora Hibernica." 



Arthonia {Ach.). 



*No. 380. — Arthonia anastomosans {Ach.). Glencar, Co. Kerry. J. C. 



*No. 381 Arthonia ochracea {Duf.). J. C. 



♦No. 402.— Arthonia patellulata {Nyl.). Demesne, Armagh. T.J. 



Gathered several years ago, but forgotten. 

 It is, I believe, a Lapland plant, not 

 hitherto known in Great Britain or Ire- 

 land.;}; Externally one might suppose 

 it a Lecidea, were it not that the apo- 

 thecia are sometimes not round, but 

 considerably elongated. There are con- 

 fused paraphyses, certainly. The spores 

 are 1-septate, 8 in asci, and pellucid; 

 they measure -0004" by •00015", and 

 with the solution of iodine the hymenial 

 gelatine becomes wine-red. 



BiEOMTCES (Pers.). 



No. 386. — Baeomyces anomalus§ {Tayl.). 



Not Baeomyces ; it proves to be Lecidea 

 Icevigata (Ach.).|| 



No. 387. — Baeomyces microcephalus {Tayl.)** Cromaglown. 

 Perhaps fungoid.
