Quick Summary

A pycnidiospore is a type of spore produced within a fungal structure called a pycnidium. The pycnidium is a flask-shaped asexual reproductive body found in fungi, particularly in the phylum Ascomycota. These spores, also referred to as conidia, are released through an opening in the pycnidium. In rust fungi, a related term, pycniospore, refers to a haploid spore involved in sexual reproduction, which fuses with another hypha to produce different spore types. Advanced fungi produce asexual spores called conidia exogenously, often grouped into specialized structures like pycnidia.1234
