Wow.
Magnificent. The king of the
forest. The iconic mushroom, the fly
aguric. If you peel the cup of the fly
agaric, and if you dry it, you smoke it
or you eat it and then it's full of
psychedelic compounds. I should confess
that I never dare to taste it. I shoot
before I die. I prefer bugandi wine or
even better shabi. What you see there is
only the tip of the iceberg only maybe
five 10% of the mass of the mushroom.
The the the real mushroom the most
active part of the mushroom is
underground making long i long filaments
of cells called the mycelium. It's like
a It's like a web, you know. It's like a
web uh growing beneath our feet and and
connecting to the trees.
A single handful of soil can contain
miles of fungal threads that form an
intricate network. Fungi are not plants.
They don't use photosynthesis to grow,
but they do need carbon.
So fungi like this have evolved to
connect to tree roots and take carbon in
the form of sugars from the tree. In
return, the fungi give minerals and
water to the tree.
The tree will provide sugars to the
network and this network will use the
sugars to fruits and make this beautiful
mushroom.
Inside the gills of the mushroom,
millions of tiny spores form. These
reproductive seeds are carried away by
wind, rain, or insects to begin new
fungal networks elsewhere in the forest.
I can feel the mycelium beneath our
teeth and are just crawling full of life
and and trying to emerge. Wow.
More than 80% of all plant species form
partnerships with the underground
mcelium. By providing nutrients and
water, fungi support the growth of the
forest.
