2 DECADES OF FUNGI. 



Caespitose, pileus hemispherical, f of an inch broad, sub- 

 carnose, quite smooth, liver-brown. Stem 1| inch high, 

 11 line thick, of the same colour as the pileus, smooth, 

 cartilaginous, composed of stringy fibres attached, at the 

 slightly incrassated base, to leaves, &c v by the reddish downy 

 mycelium. Gills fawn-coloured, nearly free, rather narrow, 

 attenuated behind ; margin thin and denticulate ; interstices 

 smooth. 



A beautiful species, somewhat resembling M. erythropus, 

 but quite distinct from every described species. 



103. M. sarmentosus,™. sp.; pileo hemispherico subspa- 

 diceo primum umbonato dense sericeo, margine involuto 

 demum expanso ; stipite vilio depresso vestito, demum 

 glabrescente eximie sarmentoso. 



On dead leaves, especially on their nerves, little sticks, 

 &c, from thence spreading and attaching itself to every 

 plant in its neighbourhood. Jamaica, Mr. Purdie. 



At first appearing under the form of a little silky tubercle, 

 varying in size according to the nature of the matrix ; this 

 soon acquires a stem, which is rapidly elongated, occasionally 

 to the extent of several inches, and remains for some time 

 perfectly simple ; more frequently, however, it becomes 

 attached to some neighbouring object by a little patch of 

 white or reddish down, so that a mass of the plant, when 

 gathered, presents quite a Flora of mosses, ferns, and dead 

 or living phaenogams. It soon throws off, at right angles, 

 short lateral branches, which are sometimes opposite, each 

 terminated by a little pileus, in general, smaller than the 

 primary pileus. 



Pileus |-1 line broad, at first subglobose from the margin, 

 being strongly involute, tipped with a conical umbo, densely 

 silky, bright-brown or tawny, at length expanded but still 

 retaining some traces of the umbo. Stem thickest at the 

 base, setiform varying greatly in length, sometimes eight 

 or nine inches long, without branching, sometimes on the 

 contrary, branched when scarcely exceeding an inch, clothed 

 at first with pale more or less closely adpressed and generally
