Pycnidium

Pycnidium (plural pycnidia) is a type of conidioma, or asexual reproductive structure, found in many fungi, especially ascomycetes. It is typically globose to flask-shaped and contains spores (conidia) produced within an internal cavity. In many pycnidia the spores are released through a small opening called an ostiole.
