Entodon beyrichii is a large pleurocarpous moss that resembles Entodon seductrix in appearance. Both are shiny green to yellow brown and have quite concave leaves with an abruptly acute apex. The cells of the mid lamina are very elongate. The most distinctive characteristics of E. beyrichii seem to be its densely (but minutely) papillose exostome teeth and its deciduous annulus (absent on E. schleicheri). The papillose proximal exostome teeth are the outer teeth on the capsule, which are smooth or nearly so on E. seductrix and cross-striate on E. schleicheri (they become papillose distally on E. scheicheri). Entodon beyrichii is at its northernmost range extent in NM, AZ, and TX. We found it growing on a rocky outcrop at about 7000 ft elevation in mixed conifer forest both in the Gila and in the White Mtns. The White Mtn. population was identified first, and pix of those plants are here.
