Abstract

The spores of Hypnum cupressiforme Hedw. var. cupressiforme, H. cupressiforme Hedw. var. lactmosunr Brid., H. cupressiforme Hedw. var. resupinalum (Taylor) Schimp. and H. jutlandicum Holmen and E. Warncke were studied. The apertural region consists of a leptoma in all of the spores. Taxa of the family are uniform, characterized by their surface ornamentation, reflecting the species' taxonomic relationships. The spore shape of all of the species is spheroid. The spore size ranged from 7 to 19 pm. in the genus Hypnum. The surface ornamentation is verrucate in all species of Hypnum. The spore walls of Hypnaceae include sclerine (the distinction between exine and perine difficult to define) and intine. The Moss species belong to corticolous habitat type. The taxonomic and ecological implications of the genus Hypinun were discussed on the basis of its spore morphology.
