188 DECADES OF FUNGI. 
'This is a very elegant species, which I referred in the first 
instance to Pol. modestus, Kze. but that species, of which I 
have lately seen authentic specimens, resembles some states 
of Pol. xanthopus and affinis. The pilei are sometimes la- 
terally connate though arising from a distinct base. 
5. P. (Apus) portentosus, n. s. giganteus, pileo carnoso 
demum friabili pulvinato vertice elevato glaberrimo azono 
cuticulo tenui alataceo vestito margine subtenui flexuoso ; 
hymenio convexo poris pro ratione pilei brevibus parvis intus 
pallidis extus fuscis, demum secedentibus, dissepimentis te- 
nuibus. 
Swan River. Mr. Drummond, n. 125. 
Stemless. Pileus a foot or more in diameter, 10 inches 
long, 6 inches thick, very light and brittle when dry, ex- 
tremely convex, especially at the vertex, which is much 
elevated, pulvinate, with about three depressions which cause 
corresponding waves in the margin of the pileus, which is 
thin in proportion to the rest of the plant, clothed with a 
delicate perfectly smooth tan-coloured cuticle. Hymenium 
convex, extending to the edge of the pileus, which is not 
inflected ; pores rather short, pale within, externally of 
a dark brown, atleast in the dry plant, small, 7, of an inch 
broad, at length separating from the pileus. 
This magnificent species is nearly allied to Pol. betulinus, 
with which it accords in many respects, but its general ap- 
pearance is very different. 'The same species, apparently, 
was gathered in Brazil by Mr. Gardner, but the specimen is 
still imperfect though of a considerable size, and consequently 
the colour is deeper than it would be in the fully expanded 
pileus. It is also minutely scabrous, a character which 
would probably vanish with age.
