134 EPPING FOREST 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 experiments 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. Their habitats vary greatly, but all derive their nourishment from decaying animal or vegetable matter. It is diffi- cult 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 years before the conditions favourable to its production will repeat themselves. The vegetative system is the mycelium, or rooting fibrils, which extend beneath the surface of the soil, and may exist for years in that condition, without producing the full development in stem, branches, or cap, which produce the fructification that is analogous to the flower or fruit of a flower- ing plant. I am indebted to Dr. M. C. Cooke, one of the greatest authorities on the subject, for the following very interesting notes on the various species most likely to be found in the Forest. He writes :— As not less than six hundred species of the larger fungi have been found within the limits of the Forest, it would only be embarrassing to give a record of all their names. We shall rest content with the enumeration of the most common, or most remarkable. EDIBLE FUNGI Amanita rubescens. Growing on the ground to the height of four or six inches, with a cap of four inches in
