In the asci arise the spores (technically, as('ox}>ores)^ usually eight in each, and these when mature are discharged from the asci, and give rise to new plants. The ascospores are formed in the asci by tho process known as free cell-formation (283). The protoplaam in the asci collects about as many ditferent points as there. Figr. 253. are spores to be formed, and a wall is then secreted about each. This mode, which is characteristic of a large number of Fungi, is quite distinct from that which prevails in the Mushrooms, where, as we have seen, the spores are formed by ahstricUon. 354. Ohara. Fig. 254 represents a Chara of the natural size. It grows almost everywhere in fresh waters, and is quite readily distinguished from other thread-like Fi;<. 253.—Very highly mayrnified view of section o an apothecium, showing the club-shaped asci.
