Can the children discover how the fungus gains access to the wood? They may find some broken limb or some place where the bark has been injured, to account for the infection. With shade and garden trees all wounds should be painted over as soon as made, to protect the trees from the spores of fungi. In gen- eral, decaying wood, stumps, branches, or trees upon which these fungi have begun to grow should be cut and burned, to prevent infection of healthy trees. Any piece of rotten wood will show how the fungous growth affects the tree. Seek for pieces that con- tain plainly visible mycelium, white threads, permeating the wood. These, as with mushrooms that grow on the ground, form the nutri- tive part of the plant, absorbing certain elements from the wood cells, thus causing them to soften and crumble. At certain seasons the spore-forming portion is pushed out into the air. Spine-Bearing or Hedgehog Mushrooms, Hydnacecz. ââ If a mushroom, instead of gills or tubes, has spines that point toward the earth, it may be called by ^"Zol\^^^^loT' either of the above names, or, botanic- ally, it is a Hydnimi. The class contains most variant forms. Some are umbrella shaped with central stems, others grow on wood and may form a mere flattened layer closely attached to it, while others may develop shelf or bracket forms, like many of the Polypori. Other species grow in branching forms, like the coral mushrooms, but are distinguished from them by the fact that the teeth or spines always point earthward instead of upward. Several common species are said to be edible, and no Hydnum described in the books is stated to be poisonous. I have endeavored to give a few suggestions that may form an introduction for a child to a large, interesting, and.
