CLASSIFICATION 195 



L. laccata. — Cap thin, convex, then often more or less wavy or 

 irregular, umbilicate, even, hygrophanous, rich brown or orange- 

 brown, almost white and minutely squamulose or velvety when dry, 

 i-2| in. across ; gills adnate, distant, coloured like the cap, at 

 length powdered with the white spores ; stem equal, fibrous, 

 coloured like the stem, tough, stuffed, 2-3 in. long (spores colourless, 

 globose, warted, 8-9 /x diameter). 



Very \'ariable in form and colour, being rich orange-brown when 

 moist, and pale buff or almost white when dry, the cap becoming 

 densely squamulose. 



On the ground in woods, etc. Very common. 



var. amethystina. — Structure and size identical with the typical 

 form, but deep amethyst or violet when moist, becoming pale lilac 

 or almost wliite, and densely squamulose when dry (spores same as 

 in the typical form). 



L. bella. — Cap rather fleshy, convex, then depressed or umbilicate, 

 orange-yellow, with small, scattered, darker adpressed squamules, 

 i-i.l in. across ; gills adnate, with a decurrent tooth, broad, rather 

 distant, yellow, connected by veins, at length powdered \\ith white 

 meal ; stem equal, tough, rivulose, yellowish, stuffed, about 2 in. 

 long. Smell foetid. 



Distinguished from L. laccata by its very foetid smell, which 

 resembles that of Clitocybe ectypa. 



On rotten fir wood. Somewhat clustered. 



Omphalia 



Cap symmetrical, usually thin, depressed or infundibuliform ; 

 gills decurrent ; stem central, distinctly cartilaginous or polished 

 outside, usually expanding upwards into the flesh of the cap ; spores 

 white. 



Agreeing with Clitocybe in having a symmetrical cap and decurrent 

 gills, but readily distinguished by the smooth, polished stem, which 

 in Clitocybe is fibrous. Separated from Collybia and Mycena by the 

 decurrent gills. 



The species are mostly small, growing on wood, twigs, etc.: some 

 grow on the ground. 



A. — COLLYBIARII 



Cap expanded from the first, edge incurved. 



B. — Mycenarii 

 Cap campanulate at first, edge of the cap straight and pressed to 

 the stem ivhen young. 



A. — COLLYBIARII 



* Usually large, gills narroic, mucli crowded. 



0. hydrogranima (PI. XI, fig. 12). — Cap thin, flaccid, deepty um- 

 bilicate. Very hygrophanous, edge spreading and rather wavy.
