Type speciesJuncigena adarca Kohlm., Volkm.Kohlm. & O. E. Erikss.

NotesJuncigena Kohlmeyer et al. (1997). was initially included under Magnaporthaceae by Eriksson (1999). Further protein coding and rDNA based phylogeny by Schoch et al. (2006) revealed Juncigena adarca clusters with Swampomyces sp. in Coronophorales. Jones et al. (2009) included Juncigena under Hypocreales incertae sedis. With resolving the TBM (Torpedospora/Bertia/Melanospora) clade with terrestrial Falcocladium, Jones et al. (2014) referred Juncigena under Juncigenaceae. Kohlmeyer et al. (1997) revealed that Cirrenalia adarca was the asexual morph of Juncigena adarca. Abdel-Wahab et al. (2010) transferred C. adarca to Moheitospora based on phylogenetic and morphological evidence. The genus currently comprises Juncigena adarca and J. fruticosae. Juncigena is distinctive from other genera in having the cylindrical, short pedicellate asci with an apical ring (Jones et al. 2014). Réblová et al. (2016b) referred Moheitospora fruticosae to Juncigena as the two genera are congeneric, and Juncigena has priority.
