CRUORIA PELLITA, Fries. 
Gen. Cuar. Frond gelatinoso-coriaceous, forming a skin on the surface of 
rocks, composed of vertical, tufted, simple, jomted filaments, set m a 
gelatinose matrix; one of the joints of each filament larger than the 
rest. Fructification, tetraspores lying at the base of the filaments. 
Cruoria (Fries),—from cruor, blood; because the plant looks like a 
blood-stain on the rock.

Descr. Fronds spreading over the surface of naked rocks, forming smooth, glossy 
_ patches of from two to three or more inches in diameter, at first nearly 
circular, but becoming irregularly lobed and sinuated at the margin when 
old, about half a line thick, tenacious, very elastic, between gelatinous and 
leathery, entirely composed of vertical filaments set in a firm, transparent 
jelly. Filaments fasciculate, perfectly simple, jointed, appearing, under a 
low power, moniliform, owing to the extreme transparency of their tube, 
composed of numerous joints filled with dense, coloured matter; joints 
about equal in length and breadth. Near the centre of every filament a 
large cellule occurs, thrice the diameter of the rest, but seemingly not 
otherwise differing, which, perhaps, performs some important office in the 
economy of the plant, though its functions are wholly unknown. = Fructifi- 
. cation (which I have not seen), apparently very rare, consisting of obovate 
clavate tetraspores, lodged at the base of the filaments. Colour of the 
frond a brownish red, or sometimes greenish or variously clouded with 
olive; of the filaments, under the glass, a pale or purplish-red.

Where a considerable surface of naked and smooth rock is 
exposed between tide marks, it may commonly be observed to 
be covered here and there with skin-like patches of a dull red
