_Filthy Gingram_ (Vol. ii., p. 467.).--The name "toad-flax" is evidently
put by mistake, in Owen's _Dictionary_, for "toad-stool," a fungus, the
_Agaricus virosus_ of Linnæus. The common name in the North of England is
"poisonous toad-stool." It is a virulent poison. See * 248. 407, 408., in
Sowerby's _English Fungi_.
