The summer tetraspores are contained in winged branchlets ; those which appear in winter are produced in curious tufted pods called Stichidia, as represented, highly magnified, at Fig. 95. Odonthalia dentata, or " toothed sea-branch," is another of our northern species of algse, and one so distinctly marked that there is no possibility of mistaking it for any- thing else. It is abundant in Scotland, in the north of Ireland, and in the Isle of Man. I have taken it very frequently near that well-known fishing station called Fig. 94. Rhodomela lycopodioides. Cullercoats, north of the Tyne, but I have never had the good fortune to meet with a fruited speci- men. The fructification of this species is curious and beau- tiful. Ceramidia are pro- duced from the axils of the branches in tufts on a delicate little pedicel or stalk, and in the same situations, on other indi- viduals, lanceolate pods or stichidia, also tufted and stalked, contain a double row of tetraspores, form- ing a most beautiful micro- scopic object. Fig. 96 represents a branch of Odonthalia, and beside it is a tuft of the pretty bell-shaped ceramidia, containing spores. The colour of.
