Technically there is no distinction between "mushroom" and "; The unsci- entific, however, generally hmit the term mushroom to the edible forms, and the lat- ter term to the non-edible and poisonous. A number of fungi are very poisonous, and many people are killed by carelessly gather- ing and eating them. One should not at- tempt to gather mushrooms for eating, un- less thoroughly acquainted with the common Fig. 170. Amanita, edible and dangerous kinds. There are (Poisonous.) ^ c ' 1 \ only a few poisonous mushrooms. A com- mon vers' poisonous form, the deadly amanita {Amentia phal- loides) usually grows in the woods, though it may occur in pas- tures and fields with edible mushrooms. This fungus looks much like the edible field agaric, but may be distinguished from it by the fact that its spores are white, not brown, in ma- turity. Moreover, it has a cup-like envelope around the stem.
