ITS FUNGI. 129 their growth. In duration they vary greatly. "Many spring up in a night and dissolve next day, or at least at the first shower of rain. Some are so delicate that they tremble in the hand when gathered, and, as in the case of Coprinus radiatus, melt away if breathed upon. Others, growing on old trees, are perennial, and almost as hard as wood." Their simplest forms consist of minute articulated filaments. Their highest developments are the brilliant domes and minarets which are called agarics, and which jewel the mossy banks in September and October. They are sought by many naturalists, not only for their intrinsic beauty, but for their varied structure, and the interesting problems which they present to the botanist and the microscopist. The bolder spirits try experi- ments in their edible qualities, but this cannot be done with impunity except by those who have acquired intimate knowledge of the varieties. The Forest Field Club annually devotes a day to a " fungus foray," and generally secures some rare and beautiful specimens. A method has been invented for their preservation with the natural colour, by Mr. English, the enthusiastic naturalist of Epping,1 to whom I am indebted for the list of Forest fungi which follows, and upon whose information, furnished to me, these remarks are founded. Their habitats vary greatly, but all derive their nourishment from decaying animal or vegetable matter. It is difficult to localise the species, as, having found a rare kind in a certain spot once, is no guarantee that it will reappear there the following year, and it may even be many 1 See Manual on the Preservation of the Larger Fungi and Flowers, published by James English, Epping.
