A '''pycnidium''' (plural '''pycnidia''') is an [[asexual reproduction|asexual]] [[fruiting body]] produced by [[Mitosporic fungus|mitosporic]] [[fungi]], for instance in the [[Order (biology)|order]] [[Sphaeropsidales]] ([[Deuteromycota]], [[Coelomycetes]]) or order [[Pleosporales]] ([[Ascomycota]], [[Dothideomycetes]]). It is often [[spherical]] or inversely pearshaped ([[obpyriform]]) and its internal cavity is lined with [[conidiophore]]s. When ripe, an opening generally appears at the top, through which the pycnidiospores escape.<ref name="Punithalingam1966">{{cite journal|last1=Punithalingam|first1=E.|title=Development of the pycnidium in Septoria|journal=Transactions of the British Mycological Society|volume=49|issue=1|year=1966|pages=19–25|issn=0007-1536|doi=10.1016/S0007-1536(66)80030-X}}</ref><ref name="RogerTivoli1996">{{cite journal|last1=Roger|first1=C.|last2=Tivoli|first2=B.|title=Spatio-temporal development of pycnidia and perithecia and dissemination of spores of Mycosphaerella pinodes on pea (Pisum sativum)|journal=Plant Pathology|volume=45|issue=3|year=1996|pages=518–528|issn=0032-0862|doi=10.1046/j.1365-3059.1996.d01-139.x}}</ref><ref>{{Cite journal|last1=Ariyawansa|first1=Hiran A.|last2=Phillips|first2=Alan J.L.|last3=Chuang|first3=Wei-Yu|last4=Tsai|first4=Ichen|date=2018-07-26|title=Tzeananiaceae, a new pleosporalean family associated with Ophiocordyceps macroacicularis fruiting bodies in Taiwan|journal=MycoKeys|issue=37 |pages=1–17|doi=10.3897/mycokeys.37.27265|issn=1314-4049|pmc=6072833|pmid=30100794 |doi-access=free }}</ref><br />
