Abstract

Hypnum subcompressum Müll. Hal. from Ethiopia is transferred to Schimperella Thér. (Brachytheciaceae) based on its evenly foliate habit with ovate-lanceolate to ovate, acuminate leaves and twisted apices; serrate to serrulate leaf margins with teeth extending nearly to the insertion; leaf bases with numerous subquadrate to short-rectangular alar cells; autoicous sexuality; blackish, cylindrical, and erect to suberect capsules; and peristome with a slightly reduced endostome. The new combination, S. subcompressa (Müll. Hal.) J. J. Atwood & Brinda, is an earlier name for S. bellointricata (Müll. Hal. ex Broth.) W. R. Buck (≡ H. bellointricatum Müll. Hal. ex Broth.), which we consider to be conspecific. Lectotypes are designated for both H. subcompressum and H. bellointricatum.
