Discusión taxonómica
(In relation to the synonym Trichomanes collariatum) This species is commonly confused with T. radicans (q.v.) but can be distinguished most readily by the broadly flaring indusial mouths, tapering blade bases with short stipes, and occurrence at lower elevations, 200–850 m. (vs. (600–)1250–2450 m).A
