Discusión taxonómica
Selaginella mosorongensis is distinguished from S. oaxacana by having long-aristate median leaves, each with a short-ciliate, basiscopic auricle, reflexed lateral stem leaves with large, long-ciliate auricles, axillary leaves short-ciliate at bases, and tan microspores. The auriculate median leaves, reflexed lateral stem leaves, tan microspores, and denticulate sporophylls of S. mosorongensis distinguish it from S. mickelii. See S. illecebrosa for differences from that species.A
