'''''Coenogonium''''' is a genus of filamentous lichens in the monotypic family '''Coenogoniaceae'''. It has about 90 species.<ref name="Wijayawardene et al. 2020"/> Most species are leaf-dwelling or grow on bark, although a few are known to grow on rocks under certain conditions, and some are restricted to growth on termite nests. The genus was circumscribed in 1820 by German naturalist Christian Gottfried Ehrenberg.<ref name="Ehrenberg 1820"/>

''Coenogonium'' has a worldwide distribution, with most species known from tropical areas. Most species grow in tropical rainforests in the shaded understorey. They typically grow on tree trunks, branches, lianas, and leaves.<ref name="Mercado-Díaz et al. 2013"/>

==Description==

Although members of ''Coenogonium'' are relatively easy to identify given its unique characteristics, identifying to species is more difficult due to the slight differences between them. The genus is characterized by {{lichengloss|biatorine}} (rarely {{lichengloss|zeorine}}), yellow to orange or brown apothecia with a {{lichengloss|paraplectenchymatous}} excipulum, partially amyloid hymenium (I+ blue then quickly sordid green then red-brown), thin-walled unitunicate asci, and 1-septate or rarely non-septate ascospores. The photobiont component of ''Coenogonium'' is a green alga from the family Trentepohliaceae.<ref name="Kantvilas et al. 2018"/> The structure of the ''Coenogonium'' thallus is largely determined by the algal partner.<ref name="Stocker-Wörgötter 1997"/>

Similar genera include ''Malcolmiella'', which differs mainly by having amyloid asci with a thickened {{lichengloss|tholus}} and non-septate, usually longer and broader ascospores with an ornamented {{lichengloss|perispore}}; ''Absconditella'', which has a {{lichengloss|chlorococcoid}} photobiont and non-amyloid asci; and ''Cryptodiscus'', which has ''Gloeocystis'' as photobiont, amyloid asci with a thickened apex and non-septate paraphyses.<ref name="Kantvilas et al. 2018"/>

==Research==

Species of ''Coenogonium'' have frequently used in morphological/anatomical and ecophysiological studies. Examples include thallus growth,<ref name="Karling 1934"/><ref name="Redinger 1934"/> apothecial development,<ref name="Schwendener 1862"/> ultrastructure,<ref name="Meier & Chapman 1983"/> photobiont and resynthesis in culture,<ref name="Uyenco 1965"/><ref name="Stocker-Wörgötter 1997"/> and photosynthesis.<ref name="Thomas & Nash 1996"/><ref name="Thomas et al. 1007"/> The filamentous thalli of ''Coenogonium'' serve as a home for diatoms and other microorganisms.<ref name="Lakatos et al. 2004"/> Johannes Müller Argoviensis even used his erroneous interpretation of the thallus organization of filamentous ''Coenogonium'' to oppose Simon Schwendener's theory of the symbiotic nature of lichens.<ref name="Müller Argoviensis 1881"/>

The genus is well known in continental areas that border the Caribbean, such as Florida and Costa Rica.<ref name="Mercado-Díaz et al. 2013"/> About half of the world's biodiversity of this genus occurs in Brazil.<ref name="Aptroot & Cáceres 2018"/>
