In their treatment of Bolivian Dennstaedtiaceae, Schwartsburd et al. (2017) included ten species in the genus Dennstaedtia . Recently, based on a molecular study, Triana-Moreno et al. (2023) have found that two species ( D. bipinnata and D. globulifera ) are more closely related to Microlepia and its segregate genus Sitobolium than to Dennstaedtia , and described the genus Mucura to accommodate them. Mucura differs from all other Dennstaedtiaceae by the combination of dichotomously branching rhizomes, petioles that lack epipetiolar buds, marginal sori with both abaxial and adaxial indusial components, and trilete spores with a unique perispore ornamentation ( Triana-Moreno et al. 2023). The distinctness of the genus is also evidenced in the key to Dennstaedtia by Schwartsburd et al. (2017), where they are separated from all other species in the first couplet.
