 nearly even ; stem flexuose, thread-like, smooth ; base swollen 

 into a little bulb, which is radiato-strigose ; gills adnate, broad,

On dead fern stems. Rare. 



This species varies in different individuals from bright orange-red to rose- 

 colour, occasionally the upper part of the stem is brown ; the gills are orna- 

 mented with a bright orange margin ; the pileus in the young state is oblong, 

 oval, obtuse, minutely furfuraceous at the apes, marked with darker, slightly 

 anastomosing veins, which at length, in consequence of the quicker growth 

 of the subjacent stratum, and the collection of the veins themselves into 

 bundles radiating from the centre, form strise on the pileus. The stem under 

 a high magnifier is often streaked with veins like the pileus. — M.J. B. A 

 variety on oak leaves is described in " Eng. Fl." 



Sect. 7. InsititicB — stem slender, dry, growing on other plants, 

 without root ; gills adnate, with decurrent tooth. 



209. Agaricus (Mycena) corticola. Sclium. " Bark Mycena." 



Pileus thin, hemispherical, at length obsoletely umbilicate, 

 sulcato-striate ; stem slender, short, incurred, furfuraceous; gills 

 broadly adnate, uncinate, broad, rather ovate, pallid. — Fr. Epicr.

Amongst moss on bark. [S. Carolina.] 



Gregarious. Pileus 1-3 lines broad, hemispherical, in general obtuse, but 

 sometimes slightly papillose, rarely umbilicate, umber, white, cinereous, 

 lilac, flesh-coloured, rufous, bluish, &c., flesh rather thick in proportion ; 

 gills variously adnato-uncinate or sub-decurrent, partaking more or less of 

 the colour of the pileus ; stem |-1 in. high, incurved, minutely pulverulent, 

 stufi'ed, and not truly fistulose, minutely strigose, or tomentose at the base. 

 The whole plant dries up in drv weather, but revives with the first shower.
