Fissidens adianthoides

Haarfarnähnliches gap -moss ( Fissidens adianthoides )

The Haarfarnähnliche gap -moss ( Fissidens adianthoides ) is a moss species from the family Fissidentaceae.

Features

The Haarfarnähnliche gap tooth moss grows in loose, green or dark green to brownish green lawn. The strong and slightly branched leafy shoots are about 2 to 10 centimeters long and dense two lines. The tongue-shaped to lanceolate leaves are narrowed to a sharp point. Against the blade tip to them are irregularly serrated on the edges. The upper Blattspreitenteil is usually shorter than the sheath member. The midrib usually ends just before the blade tip.

The single- arranged lamina cells are somewhat opaque, rounded to rounded in shape and about 12 to 20 microns in size. At the leaf margins, the cells are thick-walled and slightly lighter in 2 to 4 rows.

The reddish, up to 3 inches long seta originates in the central part of the shoots and carries the slightly curved, inclined to horizontal spore capsule. The capsule cover has a long crooked beak. Spores are nearly smooth to finely papillose and 14 to 24 microns in size. Sporophytes are often formed Sporenreife is from late autumn to spring.

The plants are monoecious or dioecious.

Habitat requirements and distribution

The moss grows on wet, base-rich, often calcareous to weakly acidic, clear to semi- shaded locations: bogs, fens, wet meadows, ditches, spring swamps, waterfalls, shores of water bodies.

Deposits are found in Europe, Asia, North Africa, the Azores, Canary Islands and Madeira, in North and South America, Australia and New Zealand. In Central Europe it is distributed from the lowlands to the subalpine zone, but not often.

Others

This gap -moss art is one of the largest Central European species of the genus. It is similar to the comb - tooth gap Moos ( Fissidens dubius ), differs from this, among other things but by other site requirements, the larger growth habit and larger leaf cells.

By draining of wet sites and other drainage measures in recent decades, the species is generally in decline.
