The uppermost lid or cap-like region of the capsule is the operculum (Fig 202), which helps in the dehiscence of capsule and dispersal of spores. The fourth study describes stomata development and internal changes in sporophyte anatomy that lead to formation of air spaces in the moss Funaria. Starting with Greek philosophers such as Aristotle and Theophrastus, this species had been mentioned in the herbal literature (in many cases, as a ‘lichen’) long before modern plant taxonomic study was applied ( Lindberg 1877 , Schuster 1966 , Bowman 2016 ).
