FIG. 5. S. HEDEEJi.
THIS generally rifes through the cuticle of the leaf
in a fomewhat conical form.
F I G . 6. S. BETULINA.
THIS feems to fwell the cuticle, forming an oblong
black fpeck on the furface, and a woolly ferruginous
margin.

FIG. I. SPH^RIA SALICINA.
T H I S differs but little from the I". Lauri, t. y]X-fig- 4.
and ought to follow it. The mouth on the upper fide
of the leaf has a fmaller covering, and the bottom of
the fphierule by its peculiar conftruaion, after penetrating
the leaf, forms a black circle, foraetimes with
a black dot in the middle.
F I G . 2. S. PERFORATA,
T H I S forms roundiih holes through the cuticle of
the fticks on which it is found, iffuing from the cortex
either fingle or in bundles, with their mouths a little
beneath the holes.
FIG. 3. S. EL1.1PSOSPERMA ? Bull. 492. Jig. 3.
THE feeds were fo conglutinated together in our
fpecimens, that we could not pofitively difcern their
elliptic forms, though we were almoft confident they
were of that figure.
FIG. 4. S. BOMBARDICA. Bolt.
A VERY common Spharia, often fpreading over old
flumps of trees; and often one over another, not unaptly
refembhng grains of gun-powder. In the young
ftate, a white powder iffues from the mouths, afterwards
a black jelly or powder, till at length they become
empty fphajrules.
FIG. 5. S. CoRTicis.
THIS Fungus reaches entirely through the cortex.
The mouth perforating the cuticle fwells it a very little,
and fometimes a ftain appears round it.
F I G . 6. S. ASPER.
WE put this among the Sphasria from its refemblance,
although it feems deftitute of the common covering
of the genus. It burfts the cuticle in fo rough
a manner as to give the ftick it grows on the appearance
of a rafp or file.
FIG. 7. S . MARGINATA.
THE mouth of this Spbteria perforates the cuticle,
and the edges turn back upon it, forming a broad
whitifh border: fometimes thefe have 2 or 3 perforations
in them, and 2 or 3 mouths beneath.
F I G . 8. S. SUBIMMERSA.
ABOUT half of each fphaerule rifes, fwelling the
cuticle hemifpherically, and giving it a dark greyiih
tinge.
F I G . 9. S. PUNCTUM.
THE fphserule is nearly round, buried in the upper
part of the cortex. The mouth perforates the cuticle,
and has round it a blackifli ftain.
FIG. 10. S. EMERSA.
THIS burfts through the cortex, forming a mouth
under the cuticle, with a fpreading black circle round
it, occafionally perforating the cuticle with a fmaller
circle or ftain round it.
F I G . II. S. CRUSTACEA.
THE cruftaceous cover of this Fungus fpreads on
the outfide of the wood, in parts forming little puftulate
fphasrute, wdth fomewhat pointed mouths.
F I G . 12. S. INSIDENS.
ALWAYS on the outfide of the wood, or nearly fo;
fometimes confluent, roughifla and hard.
