Probably throughout Europe, in similar situations. Descr. Scarcely gelatinous, forming a deep green fleecy covering to floatingplants, on which it occurs. Filaments of considerable diameter, nearlystraight. Ordinary cells of a beautifully blue-green colour, very short andcompressed, giving the filaments the appearance of an Oscillatoria; con-necting cells of a pale reddish, but sometimes the plant is of an uniform dullgreen. Thw. in litt. Spores elliptical, at length acquiring a deep browncolour. It will be seen by the figure, that the presence of a membra-nous tube to the filament, alone distinguishes this genus fromSphcerozygu. (.. Fig. 1 Spkrmosira litorea ; appearance of the mass. 2.
