Discussion

Entodon schleicheri is an uncommon Western species often confused with E. cladorrhizans. However, E. schleicheri has leaves abruptly tapering with the apicalmost cell elongate, about 4:1, whereas E. cladorrhizans has gradually tapering leaves with a short (about 2:1) apical cell. In E. schleicheri the annulus is absent, the exostome teeth are striolate proximally, and the plants are usually saxicolous. In E. cladorrhizans the annulus is present, the exostome teeth are papillose proximally, and the plants are typically corticolous.
