OMPHALIA Fr. 

 o/u0a\dc, navel. 

 These plants strongly resemble Mycena and Collybia, but 

 differ from them by having a brittle stem, with the gills run- 

 ning down it, and by the pileus being more or less depressed 

 in- the center, frequently becoming funnel-form. They are 

 usually found growing on wood, especially rotten stumps in 

 swamps and damp localities. The most common species in 

 eastern Connecticut is O. campancUa, which occurs in immense 

 numbers. The specimens photographed for illustration grew 

 on a rotten stump in a swamp in Mansfield. This is the only 

 species thus far reported in Connecticut.

CLITOCYBE Fr.

This group contains a large number of species whose indi- 

 vidual characteristics vary so much that their identification 

 is puzzling even to the experienced collector. It belongs to 

 the white-spored series of Agaricaceae, and in all species the 

 ring and volva are absent. The pileus is generally fleshy, 

 thicker in the center and narrowed toward the margin. The 

 stem is similar to the pileus in consistency, is somewhat hollow, 

 and is held by fibers on the outside so that it does not break 

 easily when twisted or bent. 



The gills are joined squarely to the stem (adnate), or in 

 many species extend down the stem (decurrent). They occur 

 usually growing on the ground, and frequently are found in 

 large groups. C. illudens is often found grouped in large 

 numbers about the bases of stumps of old trees, and C. odora 

 is equally abundant in decaying leaves. This latter species is 

 interesting because of its fragrance, which resembles that of 

 water-lilies.
