Sonae"'b'f these spores, carried by the wind, find lodgment in dead b1.'anches-or the stubs of broken-olf limbs of their favorite hosts. Here they germinate sending forth a germtube into the dead host-tissue. This..gerr.fi'tube develops into a mycelium which penetrates to the heart-wood.. '..-where it spreads in all directions but most rapidly up and down, feeding accumulating a reserve of food. The character of this mycelium and its relation to the host-tissue can be best studied in prepared sections made through the region of the black line. Study the sections provided and OBSERVE: 15. The black line. Of what is it composed? 16. The invasion of the medullary rays and wood-fibers surrounding the tracheae in advance of the black line. 17. The character of the mycelium in the region of the black line and when advancing into uninvaded tissue. 18. The character of the mycelium inside of the black line where the tissues have already been delignified. Make DRAwINGs showing the above points. After a year or more, a sporophore develops from this mycelium, usually emerging from the old infection-court. The lower surface develops a pore-layer which is annually renewed thereafter for many years. Examine the sporophore that has been sawed through and NOTE: --l9. That it is composed of many pore-layers or strata, one below the other, each succeeding one being more extensive than the preceding. Normally one layer is formed each year. DRAw. 20.
