Leptodontium luteum is readily distinguished from all other members of the genus by the irregular and coarsely marginal dentations that extends to near the leaf base; the marginal dentation is sometimes obscured by the recurved leaf margin. Other features of this species include the margins recurved more than half the leaf length, the presence of a hyalodermis (flutted), reniform costa with a single row of stereids above the guide cells, low, scattered papillae over the surface of the cell lumen. Leptodontium buesii R.S. Williams is a synonym.
 
Leptodontium luteum se distingue fácilmente de todos los otros miembros del género por los márgenes dentados irregular y gruesamente hasta a cerca de la base de la hoja; los dientes del margen algunas veces están cubiertos por el borde recurvado de la hoja. Otras características de esta especie incluyen los márgenes recurvado hasta más de media hoja, presencia de hialodermis (acostillada), costa reniforme con sólo una fila de estereidas encima de las células guía, papilas bajas, esparcidas sobre la superficie del lumen celular.
