location
Lower Trenta valley, between villages Soča and Trenta, east most part of a small riparian forest on the right bank of river Soča situated south of Otokar farmhouse, Trenta 4; East Julian Alps (Posočje, Slovenia)family
Neckeraceae
notes Slo.: zgrbljeni zavesar - syn.: Neckera crispa Hedw., Neckera pseudopennata (Warnst.) Scjlieph. & Zmuda. - Habitat: riparian forest on young alluvial deposits, flat terrain; calcareous, alluvial ground; predominantly Picea abies, some Fagus sylvatica and Salix eleagnos; in shade, high ground and air humidity; partly protected from direct precipitations by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 6-8 deg C, elevations 535 m (1.760 feet), alpine phytogeographical region (M. Wraber, 1969). - Substratum: bark of Picea abies and other trees. - Comments (pertains to pictures in the Flicker album Exsertotheca crispa): Exsertotheca crispa is a pleurocarpous moss. That means that capsules are borne on short, lateral branches. Therefore, they emerge mid stem and not at the tips of stems or branches as with acrocarpous mosses. The species is large; the longest shots can be well over 10 cm long. Capsules are relatively rare (see Fig. 22b for some). Distinctive traits of the species are glossy (whether moist or dry!) and strongly, transversely undulated leaves and wide, distinctly flattened shots. They offer a strikingly handsome look, particularly under an appropriate angle of in falling light. - Generally, the main substratum according to literature are calcareous rocks and boulders and, much less common, bark of the trunk base of trees. In rare occasions it can be found also on ground. Yet, in the Trenta valley this is different. Finds on rocks (although nearly all rocks and boulders in the region are calcareous) are relatively rare compared to extensive occurrences of Exsertotheca crispa on tree bark in the small patches of riparian forest along the river Soča. In these very humid places Exsertotheca crispa grows on lower parts of living and dead Picea abies (which are the dominant species in this habitat) and other trees. The trunks are often thickly covered by this moss from ground to sometimes well over 2 m height. - The pictures in this album show Exsertotheca crispa on three substrates: on forest ground (Figs: 1 - 3.), on dry stone fence (Figs: 10 - 13.) and on tree bark (Figs: 20 - 24.). - Ref.: (1) M.
