 A HISTORY OF SUFFOLK It was at one time supposed that the larger fungi, such as some of the Agarics, Polypori, &c., only attacked dead or decaying trees, but though the spores may only gain access through injuries or decay, the mycelium spreads into the surrounding parts, and thus kills the tree or portions of it. Another point worth mentioning is the very restricted nature of the matrix on which some alone will grow. Thus Agaricus muddus only grows on beech, Polyporus hetulinus on birch, P. dryadeus on oak. Boletus laricinus under larch trees, while many others show a marked preference for one particular species of tree, as P. squamosus for ash, P. giganteus for beech, P. sulphureus and Fistu/ina hepatka for oak, while others are not at all particular, but attack many species of trees. The same is true of the smaller fungi. The north-eastern part of the county, like the adjacent portion of Norfolk, is noted among mycologists for the very rare Trichogastres — Batarrhea and species of Geaster — which have occurred there. No one since Mr. Skepper's death has paid much attention to the smaller species, which are not given here, but may be found in the Flora of Suffolk.
