Abstract

Two moss species Trematodon longicollis Michx. and Bartramia ithyphylla Brid. have been studied with regard to morphology and spore exine ornamentation. Under SEM the exine of both T. longicollis and B. ithyphylla spores are characterized by verrucate ornamentation. On the basis of morphological characters and exine ornamentation, the taxonomic position of these two species is discussed.

Keywords
