The bryoflora of fumaroles occurring in some volcanic localities of C Mediterranean and Canary Islands is examined. The phytogeographical analysis has emphasized the presence of very rare species mainly belonging to the endemie, Mediterranean-Tropical and Atlantic elements. The very peculiar hot-hurnid ecological conditions of tropical type lead to the establishment or very specialized communities. The new combination Campylopus pilifer subsp. vaporarius is proposed.
