The
term
mushroom
usually
refers
to
the
aboveground
fruiting
body
(spore-producing
structure)
of
fungi
with
a
shaft
and
a
cap,
and
in
extension,
referring
to
the
entire
fungi
of
such
appearance,
but
is
also
used
to
refer
to
many
visible
fungi
in
general.
Mushrooms
are
used
extensively
in
cooking
many
cuisines.
However,
many
mushrooms
are
poisonous,
often
resembling
edible
varieties,
and
eating
them
can
be
fatal.
Picking
your
own
wild
mushrooms
is
extremely
risky
-
far
riskier
than
gathering
edible
plants
-
and
a
practice
not
to
be
undertaken
by
amateurs.
This
is
due
to
the
fact
that,
while
there
are
only
about
400,000
species
of
plants
worldwide,
there
are
an
estimated
1.5
million
mushroom
species.
Further
complicating
this
is
the
lower
degree
of
variety
in
easily
identifiable
traits
between
mushroom
species.
Mushrooms
and
other
fungi
are
studied
by
mycologists.
People
who
collect
mushrooms
for
consumption
are
known
as
mushroom
hunters,
and
the
act
of
collecting
them
as
such
is
called
mushroom
hunting
-
an
activity
with
potentially
deadly
outcome
that
one
should
be
well
prepared
for
before
attempting.
One
common
method
used
to
assist
in
identification
of
mushrooms
is
the
spore
print.
Psilocybin
mushrooms
possess
hallucinogenic
properties
and
are
commonly
known
as
"'shrooms".
A
number
of
other
mushrooms
are
eaten
for
their
psychoactive
effects,
such
as
Fly
Agaric.
Currently,
many
species
of
mushrooms
and
fungi
utilized
as
folk
medicines
for
thousands
of
years
are
under
intense
study
by
ethnobotanists
and
medical
researchers.
Maitake,
shiitake,
and
reishi
varieties
are
prominent
among
those
being
researched
for
their
anti-cancer,
anti-viral,
and/or
immunity-enhancement
properties.
