There is a fatally poisonous mushroom to which it bears some resemblance, and which might be taken for it, viz., Amanita _verna_, or "Spring mushroom." It is therefore necessary, in order to guard against such a mistake, to give particular attention to the characteristics of these two mushrooms. They are both white throughout, and both have white spores and ringed stem. Amanita _verna_, however, carries a white volva or cup-shaped sheath at the base of the stem, and the gills do not show a pinkish or flesh colored tinge at any stage. In Lepiota _naucinoides_, as in all the Lepiotas, the volva is wanting. Amanita _verna_ is apt to be moist and clammy to the touch, and is tasteless. L. _naucinoides_ is dry, and has a pleasant flavor. The first is found _wholly_ in _woods_; the second prefers pastures, open grassy places, and gardens, though sometimes found in light woods. I have never found an Amanita in a lawn, pasture, or garden. An edible mushroom, Agaricus (Psalliota) _cretaceus_, found in pastures, bears a slight resemblance to L. _naucinoides_, when the color of the spores and gills are not taken into consideration. In the former the gills very quickly change from their early stage of rosy pink to a dark purplish-brown color, like that of the common mushroom. The spores are purplish-brown, while in L. _naucinoides_ the pinkish hue which tinges the fading plant is very faint, and changes to a very light tan color with age. The spores being white, the gills retain their white color for a long time, never changing to dark brown. L. _Americana_ Pk. A. & S., L. _excoriata_ Schaeff., and L. _rubrotincta_ Pk. have been tested and are of good flavor. L. _Americana_ has a reddish or reddish-brown cap, umbonate, with close adpressed scales and white flesh. The gills are broad and free from the stem, sometimes anastomosing near it, white; stem white, hollow, tapering towards the cap, annulate. When dried the whole plant has a brownish-red hue. When cut or bruised it sometimes exudes a reddish juice. Miss Banning reports specimens found in Druid Hill Park, Baltimore. I have gathered very beautiful specimens in Montgomery county, Md. This mushroom sometimes grows to a very large size. L. _excoriata_ has a pale fawn-colored cap, slightly umbonate, with thin cuticle, breaking into scales; gills remote, white; stem white, hollow, and short, nearly cylindrical. Odor faint, pleasant. L. _rubrotincta_ Pk. "_Red-tinted Agaric_." Cap reddish or pinkish, broadly umbonate and clothed with adpressed scales; gills whitish, free, and close; stem nearly equal or slightly thickened at the base, with a well-developed persistent white or pinkish ring. Spores white, sub-elliptical. L. _holosericeus_ Fries has a fleshy white cap, soft, silky, and fibrillose, a solid bulbous stem, with persistent broad, reflexed ring, and free ventricose, white gills. Edible. It is found in gardens and cultivated places.
