This order contains many commonly recognized mushrooms, both edible and poisonous.

Usage Examples

• Noun:
  • The shiitake mushroom is classified within the order Agaricales.
  • Mycologists study the evolutionary relationships within the order Agaricales.

Advanced Usage

• In taxonomic hierarchy: Used in formal biological classification.
  • The family Amanitaceae falls under the order Agaricales.

Variants and Related Words

• Agaric (n): A common name for a mushroom with gills, especially one belonging to the order Agaricales.

Notes on Meaning
