Omphalia campanella Batsch. One of the most common and widely 

 distributed species of the genus is 

 the little bell-omphalia, Omphalia 

 campanella. It occurs throughout 

 the summer and autumn on dead 

 or rotten logs, stumps, branches, 

 etc., in woods. It is often clustered, 

 large numbers covering a consider- 

 able surface of the decaying log. 

 It is 1-3 cm. high, the cap 8-20 

 mm. broad, and the stem very 

 slender. 



The pileus is convex, umbilicate, 

 faintly striate, dull reddish yellow, 

 in damp weather with a watery ap- 

 pearance. The gills are narrow, 

 yellow, connected by veins, strongly 

 curved because of the form of the 

 pileus, and then being decurrent on 

 the stem. The stem is slender, often 

 ascending, brownish hairy toward 

 the base, and paler above. 



Omphalia epichysium Pers. This 

 plant occurs during the autumn in 

 woods, growing usually on much 

 decayed wood, or sometimes appar- 

 ently on the ground. The smoky, 

 or dull gray color of the entire 

 plant, the depressed or funnel- 

 shaped pileus, and short, slender 

 stem serve to distinguish it. The 

 cap is 2-4 cm. broad, the plant is 

 3-5 cm. high, and the stem 2-4 mm. 

 in thickness. 



The pileus is convex, becoming 

 expanded, umbilicate or depressed 

 at the center or nearly funnel- 

 shaped, smooth, smoky or gray 

 with a saturated watery appearance, 

 light gray or nearly white when dry. 



The gills are narrow, crowded, or a little decurrent. The slender 

 stem is smooth, hollow, equal. Figure 104 is from plants (No. 3373,
