Fig. 135. DASYA COCCINEA. 
Colour. A dull or fine crimson, becoming scarlet on exposure or in fresh water. 
Substance. Elastic ; firm ; but turning soft and decomposing after a few hours in fresh-water. 
Character of Frond. Thread-like {filamentous) ; delicately, much branched. Stems robust and 
rough with minute hair-like fibres ; generally undivided ; branched like a feather 
{pinnate). Branches simple, alternate, the lowermost longest, gradually shorter 
upwards ; twice re-branched ; the last branchlets many times forked. Stem and 
branches opaque ; branchlets jointed. 
Measurement. From 6 to 8 inches long. 
Fructification. Of two kinds ; external. 1. Clustered spores in ovate, rather pointed, capsules ; 
at the base of the branchlets : 2. Tetraspores in oblong, pointed, stichidia. 
Habitat. Our coasts generally, on rocks, &c. near low-water mark. Common. 
Var. jS. temdor is more slender in all its parts. Yar. y has naked branches, and the 
hranchiets are minute, nearly simple, their points turning in all directions {squarrose). (See 
figure of magnified branch.) For other Dasyas refer back to Plate XXV. Fig. 107 ; andfor- 
Avard to Plate XXXI. Fig. 187 ; and Plate XXXIV. Fig. 152. 
Fig. 136. CHRYSYMENIA CLAVELLOSA. 
Colour. A dullish semi-transparent red when actually growing ; soon becoming a beautiful 
brilliant pink. 
Substajice. Gelatinous ; soft ; slippery ; adhering closely to paper. 
Character of Frond. Bushy; thread-shaped {filiform)’., slender; much branched; tufted or 
solitary ; tubular. Stems undivided ; gradually widening from the base to the 
middle ; thence diminishing to the end ; alternately or irregularly branched. Branches 
long, undivided, opposite or alternate ; once or twice re-branched ; all the stems 
tapering to the base and top {apex) ; bearing one or more series of linear-lanceolate 
branchlets, closely set. They, as well as the branches, usually set at one level 
{distichous), but sometimes springing from all sides of the frond, making it a thick 
bush. 
Measurement. From 3 to 12 inches long. 
Fructification. Of twm kinds. 1. Clustered in conical, stalkless ; 2. Tetraspores 
immersed in the branchlets. 
Habitat. Various stations on the coasts of England, Scotland, and Ireland. On rocks, &c. 
near low-water mark ; and on the stems of Laminaria, at a greater depth. Not 
uncommon. 
This plant is noAV called Chylocladia clavellosa, a name by Avhich it Avas knoAvn many years 
ago. A short, very bushy variety, Avhich cannot be laid out Avithout a good deal of clipping 
of croAvded branches, is to be found on the steep sides of the rocks not far from loAv-Avater 
mark, on the north side of Filey Bridge. It never turns the rosy pink of the larger and more 
usual plant ; is less frequently dmded, and has a tendency to bear its tetraapores in groups 
(.sort), toAvards the middle and base of the branchlets. The usual {normal) form is very 
al)undant, occasionally at Filey, but, like many other algae, it is Avhimsical in its times of 
appearance. For another Chrysymenia, see Plate XXXI. Figs. 141, 142.
