Mushroom \Mush"room\, n. [OE. muscheron, OF. mouscheron, F.
   mousseron; perhaps fr. mousse moss, of German origin. See
   {Moss}.]
   1. (Bot.)
      (a) An edible fungus ({Agaricus campestris}), having a
          white stalk which bears a convex or oven flattish
          expanded portion called the pileus. This is whitish
          and silky or somewhat scaly above, and bears on the
          under side radiating gills which are at first
          flesh-colored, but gradually become brown. The plant
          grows in rich pastures and is proverbial for rapidity
          of growth and shortness of duration. It has a pleasant
          smell, and is largely used as food. It is also
          cultivated from spawn.
      (b) Any large fungus developing a visible fruiting body
          with a stem and cap, usu. of the basidiomycetes;
          especially one of the genus {Agaricus}; a toadstool.
          Several species are edible; but many are very
          poisonous. The term mushroom is used most often for
          edible varieties, the poisonous ones being termed
          {toadstools} or other names. But this distinction is
          often ignored.
          [1913 Webster +PJC]

   2. One who rises suddenly from a low condition in life; an
      upstart. --Bacon.
      [1913 Webster]
