Description:
Valves linear-elliptical with convex margins and capitate, broadly rounded ends. Length 20-31µm, width 6-9µm. Axial area narrow, linear. Central area a rectangular fascia, not reaching the valve margins. Stigma rounded, solitary placed. Raphe filiform with central endings double curved towards the stigma. Terminal fissures hooked towards the same side. Transapical striae radiate throughout the entire valve, 17-19 in 10µm.

Notes:
Grande Cascade, Ile de la Possession, Crozet Archipelago, Sample BM060 (coll. date 11/12/97).Rarely found in very dry mosses (F-value VIII).So far only found on Ile de la Possession.The taxon bears some resemblance to L. incoactoides Lange-Bertalot & Rumrich, described from the Andes, but the combination of the convex margins with the position of the stigma and the direction of the central raphe endings excludes all possible confusion. L. ledeganckii is one of the rare Luticola taxa that possess a stigma on the primary side. Most of the taxa belonging to Luticola have a stigma on the secondary side. Around the central raphe endings, several small, shallow puncta can be found.
