REINSTATEMENT FISSIDENS JONESII BIZOT EX PÓCS
Bruggeman-Nannenga (2009) considered Fissidens jonesii as a synonym of F. lagenarius . Both species share mammillose laminal cells, axillary male buds, limbidia restricted to the (sub)perichaetial leaves, ±32 columns of exothecial cells around the capsule, and short setae, but their peristomes differ. Those of F. jonesii are wider (27-43 µm versus 18-30 µm in F. lagenarius ) and have a lamellar ornamentation that consists of a neat pattern of parallel, vertical ridges stretching from trabecula to trabecula ( Fig. 6I View FIG ), whereas the teeth of F. lagenarius show an irregular pattern of wavy vertical to oblique ridges ( Fig. 6J View FIG ). More elaborate descriptions and illustrations of these peristomes can be found in Bruggeman-Nannenga (2022: figs 10, 11). Because of the different peristomes, F. jonesii is here reinstated as a distinct species.
The two species are best distinguished by their peristomes. Furthermore, they have a different substrate preference, Fissidens jonesii is restricted to tree ferns, F. lagenarius is known from branches, trunks and rotting wood.
