thumb|Phoma-Coelomycetes Pycnidium A pycnidium (plural pycnidia) is an asexual fruiting body produced by mitosporic fungi, for instance in the order Sphaeropsidales (Deuteromycota, Coelomycetes) or order Pleosporales (Ascomycota, Dothideomycetes). It is often spherical or inversely pearshaped (obpyriform) and its internal cavity is lined with conidiophores. When ripe, an opening generally appears at the top, through which the pycnidiospores escape.

thumb|Nectria cinnabarina, section of sporodochium, with young [[perithecium]] A sporodochium (pl. sporodochia) is a small, compact stroma (mass of hyphae) usually formed on host plants parasitised by mitosporic fungi of the form order Tuberculariales (subdivision Deuteromycota, class Hyphomycetes). This stroma bears the conidiophores on which the asexual spores or conidia are formed. thumb|Tubercularia fici a: sporodochium, b, c, d: showing [[setae and conidial formation]] == References ==
