390 FUNGUS-FLOEA. 



1 line thick, slightly wavy, glabrous, coloured like the pileus, 

 hollow ; spores elliptical, 6 x 3 /i*. 



Agaricus (Omphalia) sphagnicola. Berk., Outl., p. 131 ; 

 Cke., Hdbk., p. 94 ; Cke., Illustr., pi. 289a. 



On Sphagnum in swamps, &o. 



Whole plant tough and elastic. Odour scarcely any. 

 Pileus 1-1|^ in. broad, funnel-shaped from a very early stage 

 of growth, faintly striate and minutely squamulose, dirty 

 ochraceous, becoming darker in age ; moist but not viscid ; 

 gills pale, decurrent, narrow, moderately distant, thick so as 

 to present in front a flat edge. Spores white Stem 1-2 in. 

 long, 1 line thick, hollow, somewhat crooked, smooth, except 

 at first, when it is very minutely squamulose above : in age 

 it is nearly pervious above. — This species agrees in many 

 points with A. epichysium, var. icmadopliila, but its tough and 

 elastic nature is so different, that I cannot but consider it 

 distinct. The pileus is not membranaceous even on the 

 edge, which must separate it from A. pyxidaius. (Berk.) 



Omphalia philonitis. Lasch. 



Pileus J-f in. across, membranaceous, entirely deeply 

 umbilicate, margin erect, not striate, hygrophanous, floccose 

 when dry, smoky-grey ; gills deeply decurrent, rather 

 distant, narrow, lanceolate, grey ; stem hollow, 1|-2J- in. 

 long, not more than 1 line thick, equal or attenuated upwards, 

 glabrous, grey, base floccose. 



Agaricus (Omphalia) philonitis, Lasch, in Fries, Icon., t. 76, 

 f. 1 ; Cke., Illustr., pi. 289b ; Cke., Hdbk., p. 94. 



In swamps among Sphagnum, and on rotten wood. 



Differs from 0. oniscus and 0. epichysium in the longer 

 stem, the deeply infundibuliform pileus not-having even the 

 margin reflexed, and in appearing in the spring. 



The gills are too white in Cooke's figure. 



Omphalia oniscus. Fr. 

 Pileus up to 1 in. across, almost membranaceous, flaccid, 

 fragile when old, convex with an umbilicus, or infundibu- 

 liform, often irregular, undulato-flexuous, glabrous, dark- 

 grey, paler when dry, even, hoary-grey ; gills decurrent, 

 rather distant, grey, darker when dry; stem stuffed, then 

 hollow, rather firm but tough, about 1 in. long, 1 line or
