BOLETUS lucidus , pileo coriaceo iupcrnc caftaneo lucido, fulcis circularibus notato, inferne albo ; 
poris minutiffimis. 
BOLETUS rugofus. Jacquin. FI. Jujlr. t. 169. 
FUNGUS coriaceus, pileolo latiffimo atrorubente, pediculo breviffimo. Rail Syn. ed. 3. p. 11. ? 
FUNGUS fpeciofus putridis arborum truncis et dipi- 
tibus prefertim coryli innafcitur, totus lig- 
nofo- coriaceus et perfidens. 
STIPES durus, inaequalis, cadaneus, vernice veluti 
obduCtus. 
PILEUS plerumque fubdimidiatus, nonnunquam orbi- 
culatus, planus, fupeme cadaneus, nitidiffi- 
mus, fulcis circularibus concentricis notatus, 
rugofus, inferne dum recens albiffimus ; poris 
minutiffimis. 
FUNGI duo connati, in tabula proponuntur, hinc atque 
illinc fpeCtati, tum fungi pars inferior lente 
auCta ut pori magis luculenter appareant. 
This handfome Fungus grows out of the trunks of 
decayed trees, particularly the dumps of the 
hazel, and is throughout of a leathery of 
fomewhat woody fubdance, and permanent. 
STALK hard, uneven, of a chefnut colour, fhining 
as if varnifhed. 
CAP for the mod part forming half a circle, fometimes 
a whole one, flat, on the upper fide of a chef- 
nut colour, and highly polifhed, marked with 
circular concentric grooves, the edge thick 
and wrinkled ; on the under fide, when frefh, 
very white, the pores exceedingly fmall. 
Two Fungi growing together, are reprefented on the 
plate in two different views ; alfo part of the 
under fide magnified, to fhew the pores more 
plainly. 
I11 the month of November, 1780, I fortunately found the fine fpecimen of this Boletus, exhibited on the 
plate, in the Wood adjoining the Oak of Honour, near Peckham ; on fird difcovering it, the top of the Pileus 
and dalk were of fo bright a colour, and fo beautifully polifhed, that I fcarcely knew whether I had found a 
natural or an artificial production, a view of its under fide, however, foon convinced me it was natural ; it grew 
out of a rotten hazel dump. 
One principal character of this Fungus, is its polifhed or rather lacquered furface, for it has all the appearance 
of having been varnifhed ; this I believe it poflefles in all its fituations ; and on this account I have given it 
a name different from Jacquin , who has an excellent figure of it under the title of rugofus , in his FI. Aujlri- 
aca. The other characters which feem to be condant, are the deprefled circles on the upper fide of the Pileus, 
its wrinkled, thick, and fomewhat inverted edge, which is very apt to break out on the under fide of the Pi- 
leus, as reprefented on the plate, but omitted by Jacquin ; the unufual whitenefs of the pileus on its under fide 
and the extreme finenefs of its pores, which may be overlooked ; it appears to be incondant in the fhape of its 
pileus (which is fometimes orbiculatus , as is fhewn on the plate in a fmaller Fungus of the preceding year, and 
fometimes dimidiatus ) ; and in its dalk, which is fometimes wanting, as I difcovered from a lpecimen growing 
out of the bottom of an elm tree near Hyde Park. 
The dalk of the fpecimen figured, which I preferve, has not fhrunk at all, the pileus is about one third 
lefs, but retains its form and much of its beauty. 
There was fome reafon to fufpeCt this Boletus of being the perennis of Linnaeus, but the defcription given of 
that plant in his Flora Lapponica removed every doubt, and convinced me he had not defcribed it.
