In the thick peripheral membrane of Chrysymenia Agardhii an endophytic, widely spreading plant (Fig. 401) of a very characteristic appearance was found, form- ing patches of great ex- tensions in the host plant. This plant I think referable to the genus Endoderma as a new species. In dried material the Endoderma was easily recog- nizable owing to its green coloured chromatophores, filling out the whole cell homogenuously. And, as to material preserved in alco- hol, the plant in this case, too, when put into water and Iodine, was easily recognizable, the whole contents of the cells being coloured nearly black on account of the starch contained in the cells. The plant consists of long cells of very irregular shape form- ing together highly ramified filaments. The apical cells are sub- cylindrical with obtuse summits and more or less undulated walls, but soon the cells swell in the middle, this swelhng occu- pying nearly a third part of their whole length. Because of these swellings and, on the whole because of the very varying diameter of the cells, these being now thinner, now thicker and the undu-. Fig. 401.
