of the vegetable matter of which this Boletus is compofed.
I believe this plant is not before defcribed. I
found a large mafs fpreading full three feet, laft autumn,
in the hollow of an old elm in St. James's park,
forming a grotefque kind of cieling of diiferent tints.
About the fides of the cavity were beautiful varieties of
Agaricus ulmarius, and I think a variety of Agaricus
palmatus (tab. 62) hanging very fancifully, fome refembling
efcallop fliells, and others corallines, &c.
prettily relieved by the dark red wood, making a kind
of Fairy grot, remarkably clean, as if Puck had been
" fent with broom before,

BOLETUS NUMMULARIUS. Bull. t. 124.
I WAS firñ fliewn this plant on a bit of hazel flick,
and have fmce found it in Lord Spencer's park at
Wimbledon, on a Salix or willow, in various ftates, and
in other places likewife. The Rev. Mr. Abbot favoured
me with a fpecimen from Bedfordfliire. Thefe fungi
vary very much in fliape and fize, and differ alfo in
fubftance and texture according to the age or time of
gathering. At firft they are fomewhat leathery, afterwards
more horny. They are either flipitate or feilile ;
with or without a black bafe. The pores are irregular,
but fmall. May not Boletus Calceolus, Bull. t. 360
and 445, fig. 2, and alfo Boletus elegans, t. 46, of the
fame author, belong to this fpecies ?

CLAVARIA CYLINDRICA. Bull t. 463, fig. I.

of a wax-like friable nature.

C E L L U L A R I A CYATHIFORMIS. Fl Ban. t. 1450.
THIS is at prefent a new and rare Englifh plant. Our
fpecimens were found on an old deal maft near the
river Thames at Batterfea. I have fince feen fome very
fmall ones on a deal plank, that had been feafoned in
the Thames near Lambeth. It is very eafily dried,
becoming hard, refembling horn, and not changing
colour.

AGARICUS NUTANS.
A LITTLE elegant agaric, parafitic on fern ilalks,
&c. It might with fome propriety be called Agaricus
denticulatus, having uncommonly difliniSI; little teeth
at the edge of the pileus. The longer gills of this plant
have threads along their edges affixing them to the
ñipes. The gills are either fingle or in pairs. In damp
weather the pileus is fomewhat glutinous. This is
prefumed to be hitherto nondefcript.
