An introduction to recognisable Bryophyte species of Urban Parks
leafy-liverworts: marked stem and leaves.
thallose Liverworts: no distinct stem or leaves.
Some species of moss and liverwort that can be found around the Court Hey Park
Lophocolea bidentata / heterophylla– 194 records
Also known as the Bifid and Crescent leaved Crestwortsleafy liverworts, distinctive because of their size and leafyappearance, with shoots often several centimetres long,often found woven in with grasses and other BryophytesHabitat: Areas of un-disturbed Damp, shaded and moist grassland, also on rocks, plants and heathland in theright conditions.
This thallose liverwort can form large mats on almost
any bare surface, the subspecies can be separated
easily by looking at the ‘midrib’, ruderalis has a dotted
line, while polymorpha has a broad complete line both
produce a cylindrical gemmae cup with jagged edges.
Habitat: often makes use of man made habitats often being found along the joins of paving stones or almost any other urban bare ground or earth.
One of our commonest mosses its most recognisable feature’s are the wider steam leaves (which give the stem a fattened look) and the regular pinnate branching.
Habitat: This species occurs regularly in parks and grassland amongst turf and forming loose carpets over woodland often climbing the bases of trees generally favouring sheltered fairly damp conditions.
One of the smaller distinct mosses forming small tufts or with distinctive silvery nerve from a leaf that curls when dry and a slim pointed capsule held high on a orange seta when visible the capsule teeth are tightly twisted.
Habitat: This moss favours base-rich environments, often in urban areas this takes the form of old brick mortar but will also use concrete, roof tiles etc..
Not to be confused with T. muralis! Forms larger and much denser cushions but also with silvery nerve the capsules confirm as they are small and rounded on a seta that bends back into the plant.
Habitat: Often found alongside T. muralis and
favours similar habitat and so is often found
along the mortar of brick walls or on base-rich
A tall distinctive species forming dark green patches that
lighten towards the tips, when dry the shoots are tightly closed
with the silver hair point bent back at the tip of the shoot,
when wet the leaves at the head spread to form a star-burst.
Habitat: In urban areas this species can most regularly be found
In plant pots or on rotting tree stumps, posts and other dead wood.
A very urban species, this moss benefits from nitrate enrichment and flourishes in disturbed habitats, also very distinctive, forming small pale green cylindrical shoots with silver/white tips.
Habitat: pavement cracks, compact and disturbed ground at the edges of tracks and paths, plant pots, sand-dunes, stream or river banks.
When wet this species has an almost star or flower-like
look from above, however when dry the leaves curl
tightly and the shoot looks a little like a thread..
The leaf tip extends into a short hair and the moss
regularly produces capsules.
Habitat: This moss is very common and widespread and can be found in almost any habitat growing on any substrate to various sizes.
One of the more recognisable species with a leaves that curl together at the end of the shoot or branch to form sharp points, the branches themselves are irregular.
Habitat: commonly found in wetland habitats but can occur in almost any situation where wet enough, such as waterlogged turf or soil.
Highly distinctive moss, grows in amongst grasses and other mosses, it is irregularly branched and covered in leaves that bend sharply back on themselves. The head of the shoot spreads to become star-like which is noticeable even from a distance.
Habitat: Various grassland, especially where slightly
sheltered and damp can form extensive patches.
