The middle of the thallus consists of a tissue of colourless, rather poorly ramified, cell-threads which are loosely interwoven (Fig. 6b E); the cell-threads are from 2 to 12/z thick and con- sist of rather long and thick-walled cells. Towards the periphery these hyphæ-hke cell-threads are more richly ramified and here pass evenly into the radially pla- ced assimilating fila- ments, which are arran- ged in small groups (Fig. 65 A). They are dichotomously divided, moniliform, consisting of oval cells which are about 28// long and of about half that in breadth. In the upper end of the cell lies the chro- matophore, but often it fills up also more or less the whole cell; it is irregularly star-like, consisting of numerous strands which radiate from the centre of the cell in all directions (Fig. 65 F); when these strands meet each other at the periphery of the cell they grow together and form a clathrate layer with large and numerous openings with- in the cell-wall. In the central body of the chromatophore a pyre- noid is present which was densely stained by means of hæma- toxyline. The structure of the chromatophore seems thus to be in good agreement with that of Nemalion multifidum according to Wolfe's description ("Annals of Botany", vol. XVIII, 1904, p. 610) with the exception that he has not found a pyrenoid in his material. And further it also seems to agree well with that. Fig. 65. Nemalion Schrammi {M. eiS.)
