*No. 331. — Verrucaria subumbrina (JYyl). Glencree. W. A. 



This plant has been found in Ireland only 

 by Mr. Archer. As it has a cartilagi- 

 nous smooth thallus, so far not corre- 

 sponding with my Scotch plants, I 

 thought it right to ask Dr. Nylander's 

 opinion; he has named it as above. 

 This plant has eight eventually dark 

 spores in each ascus, and in size very 

 similar to the spores of Verrucaria um- 

 hrina, which has only two spores in each 

 ascus. I am sorry I have mislaid speci- 

 mens of the true V. umbrina found in 

 the Dargle. 



*No. 257.— Verrucaria Taylori {Carroll). Near Cork. T. J. 



No. 106. — Yerrucaria ? Barclay's Rock, Co. Down. T.J. . 



Mr. Carroll does not offer an opinion on 

 this Verrucaria. It belongs to Ny- 

 lander's division, Paraphyses none; has 

 large spores, -0009" by -0003", round 

 at the ends, broader at one end, obscurely 

 1 -septate, the septum not always cen- 

 tral, sometimes at one-third, and per- 

 haps the normal condition is 3 -septate. 



No. 154. Yerrucaria ? Demesne. Armagh. T. J. 



This is not Verrucaria chlorotica (Nyl.), 

 as the spores are entire ; it may be 

 Mudd's chlorotica * 



No. 190. — Yerrucaria and Lecidea. Same as No. 185. Ballymoon, 

 Co. Carlow. T. J. 



No. 192. — Yerrucaria, principally Y. rupestris (Schrad.). Ballymoon, Co. 

 Carlow. T. J. 



No. 291. — Yerrucaria (nearest Y. Dufourii) {DC), and Lecidea lenti- 

 cularis. Sheepwalk, Armagh. T. J. 



No. 334. — Yerrucaria Dufourii (DC). Rocks outside Muckross de- 

 mesne. T. J. 



See No. 1563. 

 If seen when the weather is moist, the 

 thallus of this plant resembles V. chlo- 

 rotica ; it has entire spores, and on exa- 

 mination I think it near V. Dufourii.
