features

Pseudocrossidium hornschuchianum forms fresh green to light green, loose to moderately dense and easily decaying lawns. The up to 1.5 centimeters high shoots are not very branched and have moist, upright leaves. When dry, the leaves are inflected and twisted in a spiral. They are lanceolate, gradually narrowing to the sharp point, keeled, the leaf margins strongly rolled back from top to bottom. The strong leaf vein emerges as a sharp spike tip. The leaf cells are rectangular and smooth at the bottom, round and square at the top, densely papillosome and about 8 to 15 micrometers in size. The elongated and slightly curved spore capsule on the seta , which is red below and yellow above, has long and spirally wound peristome teeth. The capsule lid is long beaked.

Location requirements

The species loves warmth and colonizes open, calcareous, loamy, sandy to stony soil in light-rich, often dry and warm places, especially on roadsides, embankments, on ruderal areas, footpaths, fallow fields, in gravel pits, quarries or in gaps in the dry grassland. Common companion mosses are Barbula convoluta , Barbula unguiculata , Phascum cuspidatum , Tortula protobryoides and some Bryum species.

distribution

In Europe, it is particularly widespread in the western, central and southern parts. Other occurrences are in Northeast and Southwest Asia, in North America, North and South Africa and in Australia.
