Kiaeria starkei occurs frequently on vertical rock surfaces, and is distinguished by the sessile male inflorescence, which is located close to the perichaetia. It can be separated in the field from the more terrestrial K. blyttii by its shiny, falcate leaves. Subalpine forms of K. falcata are more commonly found on horizontal rock surfaces and do not have grooved sporangia.
