'''''Dendroconche''''' is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, erected in 2019.<ref name=TestFielSessSund19/> {{As of|2020|February}}, the genus was not accepted by some sources.
==Description== Species of ''Dendroconche'' are usually partially epiphytic. They grow from long, creeping rhizomes that are flattened from top to bottom and bear brown scales. In some species, the rhizome may have cavities. The rhizome produces two kinds of roots: those from the sides grip the surface on which the plant grows; those from underneath enter the substrate. The leaves vary in shape from undivided to deeply divided, and are up to 70 cm long by 40 cm wide. Some species produce leaves of somewhat different shapes. The leaves may or may not have a petiole, which if present is usually winged. The leaf veins are prominent. The sori are round or elongated.<ref name=TestFielSessSund19/>
==Taxonomy== The division of the subfamily Microsoroideae into genera has long been uncertain. A 2019 molecular phylogenetic study suggested that there were three clades, comprising species previously mainly placed in ''Microsorum'', that were close to ''Lecanopteris'' sensu stricto and distinct from other clades in the subfamily. The authors of the study preferred to set up three extra monophyletic genera, rather than use a broader circumscription of ''Lecanopteris''. The genera are related as shown in the following cladogram.<ref name=TestFielSessSund19/>

{{As of|2020|February}}, the ''Checklist of Ferns and Lycophytes of the World'' recognized the segregate genera, including ''Dendroconche''.<ref name=CFLW/> Other sources did not; ''Plants of the World Online'' regarded ''Dendroconche'' as a synonym of ''Microsorum''.<ref name=POWO_17245150-1/>
The genus name ''Dendroconche'' is Greek-derived, from ''dendron'', meaning 'tree', and ''konchē'', meaning 'shell', apparently referring to the rounded leaves and growth habit of ''Dendroconche annabellae'', the type species.<ref name=TestFielSessSund19/>
===Species=== {{As of|2020|February}}, the ''Checklist of Ferns and Lycophytes of the World'' recognized the following species:<ref name=CFLW/> *''Dendroconche ampla'' <small>(F.Muell. ex Benth.)

==Distribution and habitat== ''Dendroconche'' species are native to eastern Australia, parts of Indonesia, New Guinea, New Caledonia, the Solomon Islands and New Zealand. ''D. linguiforme'' is widespread, and appears to have escaped from cultivation in India. The other species have narrow distributions. Species are found in rain forests at low to middle elevations.<ref name=TestFielSessSund19/>
