Homalia Bridel, 1827.

Homalia is not yet found in California. In Washington State it is not uncommon on trees and calcareous rocks from sea level to montane elevations. It can readily be placed in the Neckeraceae on the basis of the blunt and costate, complanate leaves with short cells. One might think of Porotrichum on first encountering Homalia, but the dentate margin of the former plant differs radically from the finely serrulate margin of Homalia.
