The Fuscous Honeyeater is the plainest of the 'tufted' honeyeaters (Lichenostomus sp.), with the least obvious tuft. It is similar to the Yellow-tinted Honeyeater, L. flavescens, which shares its range in north-eastern Queensland, but this species tends to be more yellow, with a more conspicuous black crescent-shaped mark at the ear. Other similar honeyeaters, such as the Grey-fronted, L. plumulus, and the Yellow-plumed, L. ornatus, have larger and more conspicuous yellow plumes, boldy bordered with black, and have more streaked underparts, while the White-plumed Honeyeater, L. penicillatus, has an olive-green to yellow head and a white neck plume.
