3. Structure of Mushroom
• a) What is a mushroom?
• A mushroom is a macro-fungus (big fungus)
with a distinctive fruiting body, hetero-
nutritive. It makes its food by decomposition
of organic matter.

4. Mushroom Structure
• i) Cap (pileus)- Colour (white,
grey, yellow) and shape
(umbrella, kidney, cap) depend
on species
• ii) Stype (stem)- Stype is stem
like structure that supports the
pileus and transports nutrients
from the substrate to other
parts of mushroom.
• iii) Gills -tissues that produce
spores.
• iv) Mycelia- absorbs nutrients
from substrate

5. Principles of Mushroom Growing
When a fully grown mushroom opens its cap it
releases spores, which when flown by wind and
fall on suitable substrate, under optimal
environmental condition, they germinate into
hyphae (single strand of fungus) that branches
to become mycelia and colonize. The hyphae
produces enzyme that breaks down the
substrate material, converting it into food. After
some times, mushroom pinheads appear and
then developes into a mushroom.
