Notes
Sphenomeris Maxon was conserved against Stenoloma Fee, a name of somewhat controversial application. In the Code of Nomenclature Stenoloma dumosum Fee was at first designated as type species, but afterwards, on Morton's suggestion (), this was changed to Stenoloma elavatum (L.) Fee, as this was said to agree much better with the original description of the genus. However, Fee explicitly mentioned as an essential character of Stenoloma, setting it apart from Odontosoria, the only basally attached but laterally free indusium. This is not found in any true species of Sphenomeris, and certainly not in Sphenomeris clavata. The issue should be reconsidered.
