pycnium

Pycnium is a term used in mycology to describe a type of fruiting body produced by certain fungi. It is characterized by its small size, typically less than 1 millimeter in diameter, and its dark color, often black or brown. Pycnia are often found on the surface of dead plant material or soil, and they play a crucial role in the sexual reproduction of fungi. Within the pycnidium, asexual spores called conidia are produced, which can disperse and germinate to form new fungal colonies. Pycnia are also known as asexual fruiting bodies, as they do not produce sexual spores. The term "pycnium" comes from the Greek word "pyknos," meaning "thick" or "dense," referring to the dense mass of spores within the fruiting body. Pycnia are found in various fungal groups, including the Ascomycota and Basidiomycota, and they are an important part of the fungal life cycle.
