A new California endemic species, Grimmia vaginulata, is described and illustrated. It is characterized by its very small size, julaceous habit, immersed capsule on a straight, centrally inserted seta, very large annulus, keeled unistratose leaves, autoicous sexuality, and a large cylindrical ochrea atop the vaginula that sheathes the seta to the base of the capsule. The differentiation and ecology of the new species is discussed.
