Agaricaceee 



Omphaiia. when dry even, changeable in appearance, silky, flocculose, rarely 

 squamulose, the margin, wliicli is at first in flexed, crenate (scalloped). 

 Stem short, not exceeding I in. long, almost I line thick, stuffed then 

 soon tubed, slightly firm, equal or dilated toward the apex into the 

 pileus, of the same color as the pileus, commonly smooth, but varying 

 pubescent, white villous at the base. Gills very broad behind, triangu- 

 lar, decurrent, very distant, edge of the gills straight. 



Cosmopolitan. The common form is to be found everywhere from 

 the sea level to 4,000 feet. Stevenson.

O. umbellifera.is known the world over. It is very variable in size 

 and color. With us it is seldom over X in. broad. Stem ^-1 line 

 thick. It grows on decaying wood and ground full of decaying ma- 

 terial. There are several varieties. All are edible, but not worth de- 

 scribing. This description is given that the student may recognize one 

 of our common plants, and eat it, if very hungry. 



MYCENA'RII. 



0. campanel'la Batsch. campana, a bell. Pileus thin, rather tough, 

 hemispherical or convex, glabrous, umbilicate, hygrophanous, rusty 

 yellow-color and striatulate when moist, paler when dry. Gills moder- 

 ately close, arcuate, decurrent, yellowish, the interspaces venose. Stem 

 firm, rigid, hollow, brown, often paler at the top, tawny-strigose at fJie 

 base. Spores elliptical, 6~7x3-4/x. 



PileilS 4-8 lines broad. Stem about I in. long, scarcely I line thick. 



Much decayed wood of coniferous trees. Very common. May to 

 November. Peck, 45th Rep. N. Y. State Bot. 



Spores ellipsoid, 6-8x3-4/1. C.B.P.; 7x3/x W.P.; 6-9x3-4^ B. 



The quantity alone, in which this small species can be found, makes 

 it worth mentioning as an edible species. It is common over the United 

 States where coniferous trees abound. Its favorite habitat is upon the 

 rotting debris of these trees. Occasionally it grows from the ground, 

 but only from that which is heavily charged with woody material. It 

 is social in troops, or affectionate in clusters, or maintains a single ex- 

 istence. 



It is edible, of good substance when stewed, tender and of fair flavor.
