390 FUNGUS-FLOE A. 



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

 hollow ; spores elliptical, 0x3^. 



Agaricus (Omjjlialid) spliagnicola^ Berk., Outl., p. 131 ; 

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



On S])liagnum in swamps, &c. 



Whole plant tough and elastic. Odour scarcely any. 

 Pileus 1-1 2' in. broad, funnel-shaped from a very earl}'- 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 lirst, when it is very minutely squamulose above : in age 

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

 points with A. eficliysium, var. icmadojpliila, 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. lyijxidatus. (Berk.) 



Omphalia philonitis. Lasch. 



Pileus J-J in. across, membranaceous, entirely deej)ly 

 umbilicate, margin erect, not striate, hygrophanous, floccose 

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

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

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

 glabrous, grey, base floccose.

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



In swamps among Spliagnum, 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 wdien old, convex with an umbilicus, or infundibu- 

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

 grey, jDaler when dr}^ 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
