UREDO LONGISSIMA.
P o A Aquatica, very pientiM in one part of Lambeth
Marlli, bears this parafite on the fohage early in autumn,
which gives the appearance of the frudtification
of an AJplemum. It feems nearly allied to ^. fegetum
of Bull. 2. (viz.) the fmut,as it is commonly
called, of the corn ; but this fine duft is brodai, and
imbedded in longitudinal ftreaks in the fubftance of the
foliage, covered by the epidermis, which it burils on
the front, and is vifible by being tranfparent at the
back. The fmut feems a change of the fubftance of
the feed, covered by its epidermis, and is much blacker.
See Uihilata in Bibliotbeca Bankfiana, vol. 3. p. 432, and
431. The French call it Ergot. Uredo is a new genus
oi Perfoon, in his work on Fungi.

rare, although I believe hitherto unnoticed by any
Britifli author. It is fomewhat fportive ; which, however,
in all the fungi depends much on the place of

generally of a deep buff hue, as well as the
gills, which are rather wide afunder. The ftipes is

AGARICUS opAcus. With. ed. p. 183.
T h e filvery glare and opaque furface of the pileus
will generally diftinguifh this plant; yet under particular
circumftances we have feen it without this
mark, when it occafionally reprefents A. infundibuUformis,
t. 286, and A. Jimbriatus, Bolt. t. 61. It is a very
common plant, grov/ing in woods, on heaths, &:c.
and occafionally along with A. orcades, which it re-
^mbles in flavour, but is more watery and tender.
The^opaque glare will eafily rub off when frefli, though
we have dried fpecimens that retain it.
