H ab. On dying, putrescent fungi, chiefly Boleti ; frequent in autumn.
Plant appearing at first in the form of a minute white cottony down, gradually
covering the whole fungus ; and when the latter is broken, it is
found to be filled with a mass of bright yellow sporidia, interspersed
with a few white filaments ; this seems to be the general appearance
of Sepedonium mycophilum in a mature state. The filaments are branched
and very slender. The sporidia globular, minute, excessively numerous,
and probably attached to the filaments at one period of their growth.
