The spores in formation in/are ripe towards evening ; no others were formed ; the one which apparently began to be formed in the third cell from the top in d and e has disappeared ; the cells in /, which did not contain spores, perished by about nine o'clock in the evening ; r, a quadricellular rod with ripe spores; gi, a five-celled rod with three ripe spores placed in a nutrient solution after several days' desic- cation, half an hour after noon ; g2, the same specimen at about half past one; g3, the same about four o'clock; 7ii, two spores with the walls of the mother-cells dried and then placed in a nutrient solution about forty-five minutes after eleven ; h2, the same about half past twelve ; i, k, Z, later stages of germination as explained in the text; m, a rod formed from a spore placed eight hours before in the nutrient fluid and in the act of splitting transversely ; a mag. 250, the rest of the figures 600 times. ( Borrowed from De Bary.) Generation.âFrom this point of view, Van Tieghem divides the schizomycetes into endosporous, meaning those capable of reproduction by spore formation, and arthrosporous, those in which spores are not known to ever exist. The usual mode of reproduction, however, is by fission, that is to say,. Please note that these images are extr
