The little cups or discs of the Fungus that appear on the surface are lined with vivid colors, and have delicate little bags or sacs, with seed-like spores inside. The Fungus supplies a shelter from extreme cold, and also holds water in which the Algae finds raw material. It is like a man and wife housekeeping, the man providing the house and the raw stuff flour, eggs, sugar, etc. and the wife makes these materials into food. Plants, by aid of their green stuff, work over the carbon and other materials they get from air and water and make sugar and starch, or organized food. This is their manufacture and they must have an abundance of light to do it well, so when the sea Algae grow to be immense kelps or seaweed, hundreds of feet long, they are kept afloat by their air bladders. Now, it is true the Fungus in our Lichen could not live at all without its busy Alga, which it holds in its transparent filaments, but it is not a useless partner, so we will not call it evil names. I think you will be surprised to hear, after all the warning given by these dependent and generally worthless idlers in the plant world, some of the beautiful and blooming flowers have fallen into their bad habits and are regular underground thieves. |
For the Gerardia or false foxglove has established no partnership; it is plain stealing. It still works, so it has not lost its green of the leaf, or the purple and gold of its flower, but it steals the materials for its work. When it becomes utterly idle and useless it will lose all its color and be like the ghostly white Indian pipes that grow in the shadowy pine woods. |
