notes Slo.: no name found - syn.: Jungermannia cavifolia Ehrh. - Habitat: River shore, young mixed forest on alluvial deposits, Salix eleagnos, Picea abies, Fagus sylvatica dominant; calcareous ground, flat terrain; humid air and ground, in shade; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 6-8 deg C, elevations 560 m (1.840 feet), alpine phytogeographical region. - Substratum: Picea abies bark about 1 m above ground, growing among other bryophytes and mosses (see fig. 4.: the central, somewhat bigger and slightly reddish shot is an another species not Lejeunea cavifolia). - Comments (pertain to pictures in Flicker album Lejeunea cavifolia): Lejeunea cavifolia is a small, creeping, leafy liverwort living on basic rocks as well as on tree bark. It often creeps through other bryophytes and mosses. It is a widely distributed (Europe, Asia, North America and North Africa) and quite common species, particularly in mountains, much less in low elevation plains. To distinguish it from several other similar small creatures one needs a magnifying lens or even better a dissecting stereo microscope. Namely, leaf cells have many, many oil bodies, many more than all other species of this genus. So, this is a quite reliable trait for proper identification. - Ref.: (1) Smith A.J.E., The Liverworts of Britain & Ireland, Cambridge University Press (1991), p 263.
