Our one species of Eucladium can easily be recognized. The strongly papillose leaves typical of the Pottiaceae are obvious even in the field by the opaque appearance of the leaves. The plane-margined leaves place Eucladium as unusual in a family dominated by recurved margined leaves. Even under a hand-lens the glaucous leaves and rather long stems suggest identification, and the observation of crenulate margins even of the upper leaves causes one to look for the rather large, often binate teeth on the leaf margin at the intersection of the rectangular and pellucid basal cells with the quadrate and pluripapillose cells of the limb. Eucladium, especially in the arid interior of the state, is common along seeps and springs with high calcareous or alkaline content. It is often found in areas of tufa precipitation. Another common plant in such spots is Didymodon tophaceus, which has margins recurved proximally.
