 to the apex. The uncoloured figure is insufficient to express the dif- 

 ference. (Tab. V. fig. 2. M. populiformis, natural size, with the pileus

Pileus |-1 inch across, convex, smooth, white, membranaceous. 

 Stem f-1 inch high, not \ a line thick, smooth, springing from an or- 

 bicular disc, which is hollowed out in the centre. Gills narrow, linear. 



Interstices veined. 



The disc from which the stem springs calls to mind Agaricus platy- 



pi(s, but the other characters are very different.

fiS-7.) 



Hab. On decayed trunks. January. Panure. 



Pileus 2 inches across, deeply umbilicate, brown, variegated with 



subtrlangular, pale and patent scales, which are composed of close-set 

 flocci. Stems ascending, irregular, pale, connate, rough with a few 

 furfuraceous rigid scales. Gills lilac, denticulated, decurrent, very 

 narrow below, where they are clothed with furfuraceous pubescence, so 

 as to have the appearance of ending abruptly. 



The pileus has much the colour of that sort of tobacco (bird's-eye) 

 which is variegated with paler patcTies. Tlie gills are described by 

 Mr. Spruce as lilac when fresh ; in the dried plant they are greyish.
