The plant (Fig. 384) reaches a height of about 4V2 cm (the largest specimen collected, the smaller ones were about two cm only). It is fastened to the substratum, stones, shells etc., by means of a rather large, flat disc; from this disc, one or more, erect shoots grow up. The stem of these erect shoots is terete and solid. It bears the swollen, hollow and short shoots (Fig. 385). The shape of these is obovate- pyriform reaching a length of about 8 mm and a breadth of 5 mm. The plant is, when living, somewhat translucent. The colour is red with a yellow- brown tinge. With the excep- tion of the stem, which is firmer, it is of a rather soft and slimy consistency and adheres strongly to the paper. As to the anatomy of the thallus, we find the wall of the vesicles consisting of a layer of large cells (Fig. 386 A) which on their outer side are covered more or less completely by a layer of small cells (Fig. 386 B). Seen from the surface the innermost large cells show themselves to be roundish polygonal (Fig. 386 B, C). Above the transverse walls of the large cells, where some more space is left on account of the somewhat curved surface of these cells, we find a row of roundish cells and from these again smaller and smaller roundish cells grow horizontally out over the surface of the large wall-cells (Fig. 386 B).
