. British marine algae : being a popular account of the seaweeds of Great Britain, their collection and preservation. Marine algae. CHLOROSPERME/E. 19 rocks, while C. lanosa, of a similar size, is usually parasitic on other alga?, as already described. C. glaucescens is a beautiful species, occasionally reflecting glaucous tints, as referred to in its specific name. C. Gattyce, Macallana, Broxvnii, and two or three others, com- plete the list of British species of this genus. The curious genus Codium contains some very remarkable species, two of which, except that they grow generally in masses on the surface of rocks, rarely attract the attention of ordinary col- lectors, and are certainly not common; but there is one species which is among the most singular of seaweeds, and that is Codium bursa, the Purse - like Codium. This plant is very rare; but, as col- lectors may unexpectedly meet with it, some little description of the curi- osity may not be amiss. Its habitat or place of growth is on rocks, near low water mark, and its appearance is that of a round hollow spongy ball, from one to several inches in diameter. The whole plant is made up of a very closely inter- woven mass of tubular filaments, giving to the plant the appearance of a round green sponge. Many years ago I used to find this very rare and curious species growing on one rock only, at the very verge of low water between Brighton and Botting Dene, and but that the little "mermaid's balloons," as I once heard them called, were green, one might liken them to the well-known puff-balls of the field. The species most commonly met with is C. tomentosum (Fig. 22). This plant is also singularly like one of the branching sponges. The stem. Fig. 21.
