A Great FISTULAR MUSHROON. So I call it. Given 
by Sir Rob. ■ Southwell. I find no Defcription of this Spe- 
cies. They commonly grow upon the Elm. This is * a 
Cone, as having grown to the fide of the Tree without 
(talk. The Diametre of the Bafe , near ? a yard 5 from 
whence it rifes above * of a yard in height, narrowing all 
the way to the top. Girded with feveral Rings of various 
breadth. Outwardly, very hard and denfe. Inwardly foft 
and compreflable,like a Pith, and is in fubftance really fuch. 
Confifting of an innumerable company of {mall foft 
Fibers, wrought together almoft as pure fine Wooll in a 
Hat. The bottom is all over perforated with Pores 5 of the 
bignefsof thofe little Fovea in the feeds of Poppy 5 and are 
the extremities of as many fmall (trait and parallel Pipes of 
a confiderable length, probably, almoft through to the 
top, as I have feen'them in a leffer of the fame kind. Thefe 
Pores or Pipes may be diftindtly feen without a Glafs. With 
one, a Slice of the Mujhroon looks like a piece of wood out 
of which Button-Moulds have been turn d. Both the fub- 
ftance of the Pipes, and of the other parts of the Mujhroon, 
fo far as vifible, is anfwerable only to the Cortical, or pithy 
Part of a Plant. So that it feems to be but half of a per- 
fect Plant: or wanting the Lignous Part, by which all 
Plants receive their various Figures, is a kind of Vegetable 
Mola 5 in comparifon, a rude mifhapen thing. 
Authors two ^ at w ^ lc h ^ atn formerly (a) been by me obferved

latter of wholly fibrous. 
p^tht. A fmaller FISTULAR MUSHROON, about four 
latter. inches in diametre. In which the aforefaid Pipes apparent 
ly run parallel for the length of neax two inches and \ or 
from the bottom almolt to the top.
