This is Leucostegia truncata (syn.: L. immersa).  Has a short-creeping, narrow underground rhizome.
Mature material is better to photograph or collect.

The Digital Flora of Karnataka lists Leucostegia truncata as a synonym of Leucostegia immersa (Hypodematiaceae)

The Plant List considers L.truncata and L.immersa as separate species…!

This fern was identified by expert as Leucostegia truncata (D. Don) Fraser-Jenk.
Was collected from Cherrapunji area of Meghalaya.
Please help to validate the id….

Yes, that’s it, L. truncata – as for what family it REALLY belongs to instead of the cladonomic molecular mythology – well I comment no further!
