Abstract :In this study, spore morphology of Weissia controversa Hedw., W. condensa insert ignore into journalissuearticles values(Voit); Lindb. and W. brachycarpa insert ignore into journalissuearticles values(Nees & Hornsch.); Jur. were examined by the light microscopy insert ignore into journalissuearticles values(LM); and the scanning electron microscopy insert ignore into journalissuearticles values(SEM);. All spores are small, the length of the polar axis insert ignore into journalissuearticles values(P); is between 13.39 µm and 15.0 µm, equatorial diameter insert ignore into journalissuearticles values(E); is between 17.56 µm and 18.38 µm. The smallest spores observed in W. condensa and the biggest spores in W. controversa. The shapes of all spores were determined as suboblate. Ornamentations are differing on leptoma and on distal pole. Baculate, baculate-clavate, pilate-baculate and ecinate ornamentation types were observed on the distal pole. The ornamentations are diluted on the leptoma. In addition to spore morphology, capsule structures were examined and photographed with SEM. As a result, the spore size, shapes, ornamentation types and the capsule structures show some differences among these species and these differences can be used as a distinctive character in the identification of the species
