FCNGI 39 rich earth which has fine threads of mycelium all thru it, but of course not to be seen in the mass, which will continue to grow in similar rich earth. Fig. 21 represents the mycelium of a mould that grows upon bread, and illustrates well the mycelium of the mushrooms. After the mycelium has grown for sometime and accumulated a great amount of nutrition it is ready to form spores. Then it pushes up rapidly the toad stool, puff ball, or what ever other spore bearing apparatus it may possess. The conspicuous forms that we see above the ground or on the rotting log are simply the spore bearing part of the plant, tho they grow sometimes with such remarkable rapidity as to make "mushroom growth" an often used comparison. We must remember that the forming ol the conspicuous spore bearing portions of the mushroom is but an incident in the life of the plant, and that it may have taken months of hard work tc get ready for the import- ant incident. Briefly the life of a fungus consists of: The sprouting of a minute thread from a spore; the growth of this thread into a tangled felt of mycelium which pene- trates the substance it grows upon; then the forming a spore bearing apparatus which pro- duces the spores from which the cycle begins again.
