Discusión taxonómica
(In relation to the synonym) Trichomanes hymenophylloides is closely allied to T. diaphanum Kunth (Guat to CR; Ven and Col to Peru, Braz, and Bol), but T. diaphanum has stipes alate to the bases and broadly alate rachises. For comparison with T. pyxidiferum, see that species and the key. Trichomanes hymenophylloides occurs at generally higher elevations than does T. pyxidiferum.A
