Agaricaceae 



NATJCO'RIA Fr. 

 Naucum, a nut-shell. 



Naucona. PileilS more or less fleshy, conical or convex, then expanded, margin 



(Plate LXXVIII.) 



at first incurved. Gills free or ad- 

 nate, not decurrent. Veil fugaci- 

 ous or absent, sometimes attached 

 in minute flakes to the edge of the 

 young pileus. Stem cartilaginous, 

 hollow or with a spongy stuffing. 

 Growing on wood or on the ground, 

 sometimes rooted. Spores various 

 shades of brown, dull or bright. 



Naucoria corresponds with Colly- 

 bia, Leptonia and Psilocybe; from 

 the latter it is distinguished by the 

 spore colors and from Galera in the 

 brown-spored series by the margin 

 of the pileus being at-first incurved. 

 "The spores are rust-color, or 

 brownish rust-color. The color of 

 the pileus is some shade of yellow. 

 The stem is not distinctly ringed, 

 but sometimes a slight spore-stained 

 band marks the place of the obsolete 

 ring." Peck, 23d Rep. N. Y. State Bot. 



The members of this genus are with two or three exceptions very 

 common, and common over the land. The greater number grow on 

 the ground among grass; a few grow upon decaying wood. The stems 

 are not of the same texture as the cap and frequently will not cook 

 tender; The caps, however, are, of all species tested, tender and of 

 good flavor. Species of the genus are among the first to appear in spring, 

 and well reward the enterprising mycophagist for his early tramps.
