Spore morphology of some grimmiaceae arn. Species belonging to moss flora of Turkey

This study includes spore morphology of seven grimmiaceae taxa from turkey. the spores of schistidium trichodon (brid.) poelt,s. confertum (funck) bruch & schimp.,grimmia ovalis (hedw.) lindb.,g. pulvinata (hedw.) sm.,g. trichophylla grev.,g. dissimulata e.maier and g. decipiens (schultz) lindb. were examined by light and scanning electron microscopy. the apertural region forms from a leptoma in all spores. the spore morphology of the examined taxa of the family is verrucate type. the spore shape of all studied species is prolate-spheroid. spore size ranges from 6 μm to 17 μm in the family of grimmiaceae. the spore wall of the family grimmiaceae includes sclerine and intine. the examined species of mosses are belonged to saxicolous habitat type. the taxonomical and ecological implications of the family grimmiaceae are discussed on the basis of their spore morphology. © 2016,pakistan botanical society. all rights reserved.
