This non-descript Lichen was sent to me by J. Wynne Griffith, Esq. of 
Garn, near Denbigh, who first found it on the shore of Llyn Aled lake, 
growing on stones of granite which are covered with water in the winter. 
(It has since been found about the bed of the Tees, having in its most 
common state, as Dr. Smith observes, the appearance of an ochraceous 
deposit of the water.
