some distance and sometimes clothes the shorter ones 
entirely. - 
This is a very fine and remarkable species resembling in 
some respects H. crinale, but differing in its scattered aculei 
and in several other points. The aculei are in this species 
so large and distinct that it might almost be referred to the 
genus Clavaria, so intimately are the genera connected in 
Hymenomycetous Fungi. 
16. Irpex incrustans Mont. et Berk. pileo effuso-reflexo

British Guiana. Schomburgk. On dead sticks. 
Running for several inches over dead sticks which it com- 
pletely incrusts, spreading beyond them, and forming many 
semiorbicular lobes; thin of a soft but coriaceous texture | 
indistinctly zoned above, pallid ochraceous clothed with 
short matted down. Hymenium consisting of flat acute 
slightly lobed teeth which are arranged more or less dis- 
tinctly in lamelliform series, of a more or less deep ochra- 
ceous tint. The lamelliform arrangement is very di ti 
towards the margin; but as is usual parts of the plant 
exhibit more or less distinct pores which are, howeven 
evidently not the normal structure. 
This species which illustrates admirably the genus Irpex; 
bears a strong resemblance to well-developed individuals 
Hydnum ochraceum, though the processes of the hymenium : 
are totally different. 3 :
