Definition

Noun: - A type of ascocarp: An ascoma is a fungal fruiting body that produces and contains ascospores. It is characterized by having its spore-bearing layer of cells (the hymenium) on a broad, disk-like or cup-shaped structure called a receptacle.

Examples of Usage

• Noun:
  • The apothecium, a common type of ascoma, is open and cup-shaped.
  • Under the microscope, the structure of the ascoma revealed the orderly arrangement of asci.
  • The development of the ascoma is a key stage in the life cycle of many ascomycete fungi.

Advanced Usage

• "Apothecial ascoma": Specifically refers to an ascoma that is an open, cup-shaped apothecium.
  • The lichen's reproductive structure was identified as an apothecial ascoma.
• "Perithecial ascoma": Specifically refers to an ascoma that is a flask-shaped perithecium with a small opening.
  • The pathogen forms a perithecial ascoma embedded in the host tissue.
