Microcera is a genus of Ascomycete fungi in the Nectriaceae family.
It was thought to be monotypic genus with only one species, Microcera coccophila {{Au|Desm. (1848)}}Desm., Annls Sci. Nat., Bot., sér. 3 10: 359 (1848) As well as former species Microcera coccophila var. platyspora {{Au|Sousa da Câmara (1920)}} being reclassified as Microcera coccophila. Microcera coccophila was initially found on the bark of young living trees of Salix and Fraxinus in France.{{cite web |title=Species Fungorum - GSD Species |url=https://www.speciesfungorum.org/Names/GSDSpecies.asp?RecordID=249367 |website=www.speciesfungorum.org |access-date=12 August 2023}}
The genus has been considered as a synonym of genus Fusarium {{Au|Link}} in major taxonomic revisions.{{cite book |last1=Wollenweber |first1=H.W. |last2=Reinking |first2=O.A. |title=Die fusarien, ihre Beschreibung, schadwirkung und bekämpfung |publisher=Paul Parey |location=Berlin, Germany |pages=1–355}}{{cite book |last1=Booth |first1=C. |title=The Genus Fusarium |date=1971 |publisher=Commonwealth Mycological Institute |location=Kew, UK |pages=1–237}}{{cite book |last1=Nelson |first1=P.E. |last2=Toussoun |first2=T.A. |last3=Marasas |first3=W.F.O. |title=Fusarium Species: An Illustrated Manual for Identification |date=1983 |publisher=Pennsylvania State University Press |location=University Park, PA, USA |pages=1–193}}
Then Gräfenhan et al. in 2011 resurrected genus Microcera based on DNA sequence data and accepted four Microcera species, viz. M. coccophila, M. diploa {{Au|(Berk. & M.A. Curtis) Gräfenhan & Seifert}}, M. rubra {{au|Gräfenhan & Seifert}} and M. larvarum {{au|(Fuckel) Gräfenhan, Seifert & Schroers}}. Lombard et al. then further investigated phylogenetic relationships of Microcera based on DNA sequence data and reported that it constitutes a lineage distantly related to Fusarium but closely related to Fusicolla and Macroconia. Both within the Nectriaceae family.{{cite journal |last1=Lombard |first1=L. |last2=Merwe |first2=N.A. |last3=Groenewald |first3=J.Z. |last4=Crous |first4=P.W. |title=Generic concepts in Nectriaceae. |journal=Stud. Mycol. |date=2015 |volume=80 |pages=189–245}}
Then in 2021, 3 fungi were associated with Kuwanaspis howardi, a scale insect found on Phyllostachys heteroclada (fishscale bamboo) and Pleioblastus amarus (bitter bamboo) in China. New species Podonectria kuwanaspidis {{au|X.L. Xu & C.L. Yang}} sp. nov. and Podonectria novae-zelandiae {{au|Dingley}}, (both in Podonectriaceae family, Pleosporales order) as well as Microcera kuwanaspidis {{au|X.L. Xu & C.L. Yang}} sp. nov.
It has a cosmopolitan distribution worldwide.{{cite web |title=Microcera Desm. |url=https://www.gbif.org/species/2556549 |website=www.gbif.org |access-date=12 August 2023 |language=en}}
