ted warts finally with spines. The thick, older cell-wall is brownish (Figs. 4, 9

R 10). The cells contain much rose-coloured oil, hardly any starch. Pyrenoid was not visible in the cells. Reproduction takes place by autospore formation. The daughter individuals with thin, smooth cell-wall escape by means of the gelatinization of the cell-wall of the mother cell (Figs. 5,6). This microorganism bears resemblance most to the Trochiscia americana KOL species. It differs from it, however, on the basis of the following features: 1. the cell is light brick-red. 2. the wall of the cell is ornamented with warts. 3. it is smaller. KOL (1968) found the Trochiscia americana KOL species to occur in several places of the North American Rocky Mountains, from where she had described it first. References BOHLIN, K.
