Since I publifhed my defcription of this fpecies, I have difcovered the 

 blue variety in Llyn Cwellyn, and examined it carefully on the fpot with a 

 compound microfcope. The principal items were entirely deftitute of 

 whirls, but the ends precifdy refembled thofe of the plant in its common 

 (late, the color alone excepted. I am inclined to think that the fingular 

 appearance of this variety arifes from difeafe, probably occafioned by its 

 alpine fituation, and its growth in ftagnant water, but at all events it has 

 no claim whatever to be confidered a diftindr. fpecies. 



92. atra. C. filis ramofiflimis, moniliformibus, fub-gelatinofis, atro-viridibus ; 

 ramulis fetaceis ; articulis diametro quintuplo longioribus, fuperne incraf- 

 fatis, verticillato-ciliatis. T. 1 1 and T. D. 



Since the publication of this fpecies it has alfo been found at Bantry by 

 Mifs Hutchins, and near Cambridge by Mr. Relhan, who firft difcovered 

 the frudtification, which has been fubfequently found about Yarmouth by 

 Mr. Turner and Mr. Hooker. The fruit is large, globular, and fertile, of 

 a dark color, and fcattered plentifully over the frond, efpecially near tho 

 bafe, in which refpeft it differs from moft other Confervse. Although the 

 powers of my microfcope did not enable me fatisfadlorily to determine, yet 

 I have but little doubt that thefe capfules referable in their nature thofe of 

 C. gelati'cfa; they are reprefented in my fupplementary plate D magnified I.
