S.denticulatum is a common species in very wet acidic habitats on the Lawers hills, especially on flushed slopes and rock faces.  Plants are often a bright orange colour and show the curved branches typical of the species.

Distichium capillaceum

Meall Corranaich
Distichium capillaceum is a common species on damp calcareous crags on the Lawers hills.  It is usually abundantly fertile, maing it easy to recognise.

Dichodontium palustre

 
 

 

 

Dicranoweisia crispula

 
A common species on exposed schist on all the Lawers hills, D.crispula is recognisable by its crisped leaves when dry and the usually abundant capsules on a yellow seta.

bcE corrie of Ben Lawers
One of very few mosses endemic to Britain, this species was only recognised as distinct in the early 1980s.
In the field is resembles B.ferrugunascens but always grows in permanently wet sites.  Under the microscope, the broad leaves with abruptly tapered, strongly toothed apices make it instantly recgnisable.
Unfortunately I didn't get a photo of this plant in habitat as the persistent rain had fogged up the lenses - I'll have to go back on a better day!

B.caledonicum is restricted to Scotland, where it found at scattered montane sites from Skye to Perthshire.

Schistidium frigidum var.havaasii

sfMeall Corranaich
This very rare Schisitidum is another of the specialities of the Lawers range.  It is known from Ben Lawers and Meall Corranaich and is very scarce on both hills.

In the field it is distinctive in its small size, greenish colour and capsules on a short seta.  The capsules are not as abundantly produced as in S.dupretii.

Under the microscope, S.frigidum has strongly sinuose leaf cells, a border of basal cells with distinctly thickened margins and the nerve ends below the leaf apex.

Nationally, S.frigidum var.havaasii is known from only seven 10km squares, only three of which have been observed since 1990.  It is a near endemic plant, otherwise only known from western Norway.

S.frigidum var. frigidum is more frequent, having been recorded from twelve hectads, and is much more widespread globally.

leaf section, Ben Lawers
 
A common moss of exposed acidic rocks in upland areas western and northern Britain, R.sudeticum is a common sight on Ben Lawers and its neighbouring hills.

Under the microscope, R.sudeticum has a distinctive leaf section, with a tristratose (3-cells high) nerve and a leaf lamina one cell thick apart from at the margins, which are bistratose for one or two rows.

Meall Corranaich
One of the real gems of the Lawers range, this attractive moss is extremely rare in Britain and known from only _____________ sites, one of which is a well-known population on Meall Corranaich.

It is an easily recognised species (in Britain at least), resembling a translucent, pale green, soft-textured Polytrichum species, and quite unlike any other British moss.

T.austriaca is much more common in the mountains of continental Europe, where it occurs with the very similar-looking T.bavarica.  You can see photos of both of these species and read more info in the ___________ section of the site.
