AGreatFISTULAR MUSHROON. So I call it. Given 
by Sir /?oZ>. Southwell. I find no Defcnption of this Spe¬ 
cies. They commonly grow upon the Elm. This is Li 
Cone , as having grown to the fide of the Tree without 
ftalk. TheDiametre of the Bafe, near i a yard; 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 com preflable,like a Pith, and is in fubftance really fuch. 
Confiding of an innumerable company of fmallfoft 
Fibers, wrought together almoftas pure fine Wooll in a 
Hat. The bottom is all over perforated with Pores 5 of the 
bignefs ot thofe little Fovea in the feeds of Poppy • and are 
the extremities of as many fmall ftrait and parallel Pipes of 
a confiderable length, probably, almoft through to the 
top, as I have feen them in a Idler of the fame kind. Thefe 
Pores or Pipes may be diftinctly feen without aGlafs. With 
one, a Slice of the Mufhroon 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 Mufhroon, 
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 
Mol a ; in comparifon, a rude mifhapen thing. 
That which hath formerly (a) been by me obferved 
with the help of Glaftes, by the Pith of this Mufhroon is 
further confirm’d , and clearly reprefented to the naked 
eye, fc. That the Pith of a Plant, as well as the Wood, is 
wholly fibrous. 
A fmailer FISTULAR MUSHROON, about four 
inches in diametre. In which the aforefaid Pipes apparent¬ 
ly run parallel for the length of near two inches and I, or 
from the bottom almoft to the top.
