Plagiotheciumschofieldii, a new species from the Aleutian Islands (Alaska, USA).

ABSTRACT: Plagiotheciumschofieldii sp. nov. is described from the Aleutian Islands, Alaska, U.S.A. Some morphological features of this species correspond to P.lamprostachys (Southern Hemisphere species); however, Plagiotheciumschofieldii is genetically and morphologically different from this and other common Northern Hemisphere species e.g., P.denticulatum, P.platyphyllum, or P.ruthei. The most important distinguishing morphological features differentiating this species are: the arrangement of the leaves on the stem; dimensions, concavity and symmetry of the leaves; dimensions of cells and their areolation; orientation of capsules. Additionally, due to the strong concavity of the leaves, they are very often badly damaged under the microscope. We prese
