In this study, the spore morphologies of five different acrocarpous moss species (Weissia brachycarpa, Distichium inclinatum, Pterygoneurum ovatum, Ceratodon purpureus and Ptychostomum donianum) were investigated and discussed the taxonomical and ecological value of spores morphological characters of these species. Spores were prepared according to standard palynological techniques such as acetolysis and Wodehouse and analyzed using light microscopy to reveal sporoderm structures. The spores of the three moss species except Pterygoneurum ovatum and Ceratodon purpureus which are heteromorph are heteropolar and monolete. Also, in all species, the shape of the spores was determined as suboblate in equatorial view. In polar views, the shapes of spores vary as oblate-spheroid and suboblate. In equatorial view of the spores, the length of the polar axis (P) range from 9.60 μm to 27.90 μm on average, the length of the equatorial axis (E) is between 12.00 μm and 31.96 μm on average. The sporoderm layers of the spores were also examined and measured. It has been determined that the spores of the examined species have five different ornamentation types as verrucate, clavate-gemmate, baculate, clavate and baculate-clavate. The results obtained are discussed in terms of taxonomical and ecological aspects.
