British Guiana. Schomburgk. 
Pileus i-9 inches across, coriaceo-suberose rather rigid 
about a line thick orbicular deeply incised and lobato- 
crenate depressed umbilicate repeatedly zoned concentri- 
cally, with the zones waved from radiating slightly ru- 
gose lines, sericeo-striate, rather shining, but not the 
least laccate, of a brown umber as is also the internal 
Substance, Stem 14 inches or more high, 4 a line thick, of 
the same colour as the pileus flexuous marked with short 
longitudinal pits either perfectly central or lateral. Hyme- 
nium sepia-brown approaching to black, slightly concave; 
even; pores very minute, scarcely visible to the naked eye, 
about + of a line deep: dissepiments very thin. 
This species in some respects resembles Pol. auriscalpium, 
which has the stem occasionally central; but from an in- 
spection of authentic specimens of that plant, it appears that 
t is a far more elegant and very distinct species. The pileus 
has not the slightest laccate crust, though this point is not 
always to be depended on.

The stem in these specimens is 
the species, but of the same colo
