…The process of formation does not involve meiosis, so the nuclear phase of the conidia is the same as that of the parent hyphae. They are usually formed in a naked state on a specific hypha called a conidiophore, but they can also be formed inside a sac-like structure called a pycnidium. Conidia are unicellular or multicellular, and vary in shape, size, color, and formation process. Among fungi, especially in the Deuteromycetes, where sexual reproduction is not known, the characteristics of conidia are important criteria for classification. … *Some of the terminology explanations that mention "pycnidium" are listed below.

…形成の過程で,減数分裂をともなわないので,分生子の核相は母菌糸のそれと同じである。ふつう分生子柄conidiophoreという特定の菌糸上に裸出した状態で形成されるが,分生子殻pycnidiumという囊状の構造の内部に形成されることもある。分生子は単細胞または多細胞で,形,大きさ,色,およびその形成過程はさまざまであり,菌類のうちでもとくに,有性生殖の知られていない不完全菌類では,分生子の特徴が分類の重要な基準となる。… ※「pycnidium」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
