✨ Characters of Agaricus (Specimen)

  1. The common edible mushroom is the fruiting body (basidiocarp) of Agaricus.

  2. It is a saprophytic fungus that grows in humus-rich soil with semi-decomposed organic matter.

  3. The thallus is an underground, interwoven mass of thick, colourless hyphae.

  4. The fruiting body:

    • Young → spherical, button-like.

    • Mature → differentiated into two parts:
      (i) Stipe (stalk): Erect, formed of vertically arranged hyphae.
      (ii) Pileus (cap): Umbrella-like structure attached to the stipe.
      - At the base of stipe is a ring (annulus), the remnant of the young covering.

  5. On the underside of pileus, there are gills (radiating plates).

    • Gills bear basidia and basidiospores.

👉 Based on these features, the specimen is identified as Basidiocarp of Agaricus.
