Definition

Noun: * A species of inky cap mushroom, scientifically classified as Coprinus atramentarius, commonly known as the common inky cap or tippler's bane. It is characterized by its bell-shaped, grayish cap that undergoes autodigestion (deliquescence), liquefying into a black, inky fluid as the spores mature.

Usage

This term is used in scientific, mycological (fungal), and foraging contexts to specifically identify this mushroom species. It is a formal, taxonomic name.

Examples
  • Scientific Identification: "Under the microscope, the spores of were clearly visible."
  • Foraging Warning: "While some mushrooms are edible, contains coprine, which can cause a severe reaction when combined with alcohol."
  • Descriptive: "We found a cluster of growing on an old tree stump; their caps were already beginning to liquefy at the edges."
Advanced Usage
  • Chemical Interaction: The compound coprine found in this mushroom inhibits the enzyme acetaldehyde dehydrogenase. When alcohol is consumed, acetaldehyde builds up in the body, causing an unpleasant "disulfiram-like" reaction (flushing, nausea, palpitations). This is the origin of its common name "tippler's bane."
  • Taxonomic Note: While traditionally placed in the genus , some modern classifications may place it in the genus (e.g., ). However, remains the widely recognized name.
