V I O L E T F U L I G O.

G E N E R I C C H A R A C T E R.

A fungus that is initially pulpy, most often diffuse and formless; covered with a fibrous or villous outer bark, membranous at its base; of a cellular and fibrous tissue, hairy inside, reducing with age into dust.

S P E C I F I C C H A R A C T E R.

Dilated, violet; outer bark yellow, thin, deciduous, filled internally with a compact, very black dust.

It is found on the trunks of pine trees in autumn, but not commonly.

Its width extends up to 2 or 3 inches; in its fresh state, its crust is golden yellow; its substance is very soft, but when it is dry it becomes more or less friable; in this species, the crust is often entirely destroyed, so that the cryptogame non-flowering plant/fungus appears only as a mass of a pleasant violet-purple, varied here and there with whitish villosity; its internal substance and cells are of a whitish-rust color; the powder is brownish-black.
