1 Selliguea lauterbachii is usually easily recognisable by the narrow fertile fronds with separate sori, and the usually squarrose, strongly dentate, brown rhizome scales. It can be similar to forms of S. plantaginea, S. costulata and S. tafana. Some specimens have fronds that are intermediate to S. plantaginea, gradually narrowed from a wide, sterile base to a narrow, fertile apex.

Selliguea costulata frequently has interrupted coenosori, thus blurring the distinction from S. lauterbachii. Selliguea tafana can be distinguished by the blackish rhizome scales which are less strongly dentate, the relatively short fertile fronds, and the frequent occurrence of small scales on the fronds. It usually occurs at higher altitudes than S. lauterbachii, but especially sterile specimens from the intermediate range cannot always be identified.
2. In very narrow fronds the coenosori are elongated longitudinally, in somewhat wider fronds they are distinctly oblique, directed towards the margin, forming a transition to S. plantaginea.
