Mushrooms are fungi that produce fleshy fruiting bodies, often with caps and stalks. They have two main parts - the cap and the mycelia, which are thread-like structures that absorb nutrients from the soil without needing sunlight. There are six main types of mushrooms cultivated worldwide - paddy straw, oyster, button, milky, shiitake, and Jew's ear mushrooms. Mushrooms have specific temperature and humidity requirements for growth, such as button mushrooms preferring 20-28°C and 80-90% relative humidity over 50-60 days.

2. Introduction to Mushroom
 Mushroom is a fungi producing a fleshy fruiting body, especially one consisting of a stalk
with an umbrella cap.
 It has two part:
 Cap like structure is known as PILEUS.
 Attached with thread like structure MYCELIA.
 Mycelia absorb nutrient from the soil, it do not require sun light for their growth.

3. TYPES OF MUSHROOMS
Mostly only six mushrooms are widely preferred for large-scale cultivation.
 Paddy straw mushroom - Volvariella spp.
 Oyster mushroom - Pleurotus spp.
 Button mushroom - Agaricus spp.
 Milky mushroom - Calocybe spp.
 Shiitake mushroom - Lentinulla spp.
 Jew’s ear mushroom - Auricularia sp.
