After De Bary. sexual reproduction is more simple. They are produced by slightly varying modes, as a result of the conjugation of opposite threads. These hyphae, either within or without the body of the host, produce lateral outgrowths at opposite points of two different threads, which meet midway between the two conjugating cells, and coalesce. The intermediate walls are absorbed, and a connecting tube is formed, through which the contents are mingled (Fig. 39). A gemma is produced on the connecting canal, which increases rapidly, appropriating the contents of the two conjugating cells to form a zygospore. After this the empty hyphae disappear. This process may be slightly modified in different species, but it follows the same principle, and the mature zygospore passes into a period of This much is known of sexual reproduction in Fungi: that 1 Vegetable Wasps and Plant Worms, by M.
