Note 357 — ENGLAND.
Reading edition
In Northumberland the common people call a certain fungous excrescence, sometimes found about the roots of old trees, Fairy-butter. After great rains and in a certain degree of putrefaction, it is reduced to a consistency, which, together with its colour, makes it not unlike butter, and hence the name.
