250 FUNGI. 



support them are so slender that they shake and quiver 

 in every breeze. The colour is grey, shaded dark to the 

 summit of the bell, and pale to the margin ; the folds 

 are white at first and then become greyish. The smell is 

 like that of walnuts ; and the plants perish as rapidly as 

 they appear. Another pretty species of this group, sent 

 to us from the Somersetshire woods, is the pale green 

 Mycena (M. epipterygius), it grows among fern leaves, is 

 decidedly green in hue, and in other respects resembles its 

 allies. 



On a twig of bramble I found a cluster of slender 

 Agarics, their stems thread-like, their caps pure white. 

 The twig was in a decaying state, lying amongst fallen 

 leaves in the Chase Wood, near Eoss, in Herefordshire. 

 The fungus was the bramble Mycena (M. roridus). 



The folds turned down the stem mark the Omphalia 

 group. A pretty species of Omphalia attracted my 

 attention as it grew from the margin of a peat-bog on 

 the Yorkshire moors, very early in my fungus experi- 

 ence. It is a small plant, not measuring more than two 

 inches across ; the cap depressed in the centre, so as to 

 earn for it the name of Cup Omphalia (0. Pyxidatus, 

 Plate XVII., Jig. 7), and striped and puckered at the 

 margin. The colour of the whole plant is a bright ochre. 



The Orange Omphalia (0. fibula, Plate XVII, Jig. 16) 

 is a slender and elegant species. AVe found it in the 

 grounds of Craig House, near Edinburgh — parasitic on a 

 dead leaf. 



The Pleurotus group has either a one-sided stem or no 

 stem at all. There are some very handsome species, as 

 the Meadow and Oyster Pleurotus (P. ulmarius and
