For the most part they do not form mycelia, but increase by budding and by the formation of spores. Saccharomyces cereviseoB is the well-known Brewer's Yeast. The cells are oval and colourless, and provided with one or more conspicuous vacuoles; the cell-nucleus is not readily demonstrable, though there is little doubt of its existence. Growth here is by budding, little processes being pushed out at the periphery at one or more spots and gradually enlarging (figs. 387*-^'^); ultimately they are cut off from the parent-cell by the completion of the membrane across the point of union.
