Barbilophozia barbata

bb

bb
Le Boreon, Mercantour PN
This attractive liverwort is widespread in the French Alps, although the plants shown here are the only ones I have come across on my travels so far.

I've described B. barbata in the Liverworts of Derbyshire section of the site, where it is a great rarity!

 

 

Tritomaria scitula

ts

ts
below Cime Nire, Val Gordolasque, Mercantour PN
This pale liverwort is reasonably widespread in the French Alps, where it is found on damp, base-rich rocks.  It resembles other Tritomaria species in its lobed leaves but is distinctive in the field in having brown gemmae at the tips of the shoots.  The leaf lobes are also more rounded than in T. quinquedentata.

 

 

Gymnomitrion concinnatum

below Cime Nire, Val Gordolasque, Mercantour PN
The most widespread Gymnomitrion species in the French Alps, this little liverwort is typical of cold, damp sites where snow lies late in the year.

I've described this species in more detail in the Liverworts of Ben Lawers NNR section of the site.

Scapania aspera

sa
below Col de la Bonette, Mercantour PN
Scapania aspera is the most widespread member of the genus in the French Alps and is found over a wide altitudinal range.  It is a typical species of damp limestone.

This species is described in more detail in the Liverworts of Derbyshire section of the site.

 

 

Scapania scandica

Radula lindenbergiana

rl
below Cime Nire, Val Gordolasque, Mercantour PN
This greasy-looking liverwort is fairly widespread in the French Alps, although the recent 'Mousses et Hepatiques des Alpes francaises' (Legland & Garraud, 2018) shows it as not observed in the Maritime Alps since 1990.

I've described this species in more detail in the Liverworts of Ben Lawers NNR section of the site.

Sphagnum capillifolium

sph
Val Gordolasque, Mercantour PN
More than a dozen Sphagnum species are recorded from the Maritime Alps, with this species being one of the most common.  While S.capillifolium is often pinkish-red, all of the plants I saw here were a dingy yellow-green.

This species is described in more detail in the Mosses of Scotland section of the site.

 

 

Sphagnum squarrosum

sq
Le Boreon, Mercantour PN
S.squarrosum is a very distinctive species and widespread in the French Alps. 'Mousses et Hepatiques des Alpes francaises' (Legland & Garraud, 2018) shows it as not observed in the central Maritime Alps since 1990, so this perhaps represents a new record for the area.  The plants here were growing on a seeping soil bank beside a track in larch forest.

This species is described in the Mosses of Ben Lawers NNR section of the site.

 

 

Andreaea rupestris

ar
by Lac Negre, Le Boreon, Mercantour PN
Three Andreaea species are recorded from the Maritime Alps - alpestris, frigida and rupestris.  I collected this in the hope it was the rare (and tricky to identify) alpestris, but microscopically it was confirmed as the common and widespread A.rupestris.

This species is described in more detail in the Bryophytes of Cumbria section of the site.

 

 

Polytrichastrum alpinum

pa
Val Gordolasque, Mercantour PN
This common alpine species is found on fairly dry rock ledges where some soil has accumulated.  It is the most common Polytrichum species in rocky habitats at higher altitudes.

I've described P.alpinum in more detail in the Mosses of Ben Lawers NNR section of the site.

 

 

Flexitrichum gracile

dg
Val Gordolasque, Mercantour PN
One of the commonest acrocarpous mosses of damp, calcareous rocks across Europe, this little species is often a dominant species on sheltered, base-rich crags.  Its name was recently changed from Ditrichum gracile.

F. gracile is described in the Mosses of Derbyshire section of the site.

 

 

Saelania glaucescens

sg
Col de la Bonette, Mercantour PN
sg
Col de Tende, Roya
This unusual moss is a great rarity in Britain, where it is only known from a series of limestone outcrops in Scotland which experience a distinctly continental climate.  In the Alps, it is much more frequent, although I have only seen it in small quantity in any one place.

Saelania is instantly recognisable in the field due to its ghostly grey-green colour.  This is caused by the leaves being covered in very fine fungal hyphae.  It grows in rock crevices and is often fertile, bearing cylindrical capsules on short setae.

Hymenoloma crispula (syn. Dicranoweisia crispula)

dc
Val Gordolasque, Mercantour PN
This very common montane species is easy to find almost anywhere in the French Alps.  It is worth looking carefully in case the very similar but much rarer H. compactum is present.

This common montane moss is described in the Mosses of Ben Lawers NNR section of the site.

 

 

Weissia controversa

wc
Col de Tende, Roya
Along with the very similar W.brachycarpa, this is the most widespread Weissia in the French Alps, although both species are more subalpine and lowland in their distribution.  W.wimmeriana is very similar to W.controversa but is distinguished by being paroicous.  It occurs at higher altitudes than W.controversa.

This species is described in the Mosses of Derbyshire section of the site.

 

 

Tortula hoppeana

th
Le Boreon, Mercantour PN
This montane species is widespread in the Alps and often easy to spot, thanks to its abundant capsules.  It shares its habitat with Syntrichia ruralis, and the two are superficially similar in the field.

T.hoppeana can be recognised by its unbordered leaves which have papillose cells in their upper half and often have a green hair-point (although this is sometimes absent).  The peristome is simple.

 

 

Tortula subulata

ts
Col de Tende, Roya
This common species is a colonist of sunny, dry ground, where it can grow alongside T.hoppeana (above).  In the French Alps, it tends to be a subalpine species, only rarely ascending to high altitudes.  T.subulata grows on soil, rather than directly on rock and has bordered leaves, unlike T.hoppeana.

The species is described in the Mosses of Derbyshire section of the site.

Grimmia unicolor

gu
Val Gordolasque, Mercantour PN
In Britain, this unusual Grimmia is a great rarity.  In the mountains of Europe, it is much more frequent, where it is characteristic of damp, hard volcanic rocks, particularly at the base of crags.

Microscopically, G.unicolor has a very distinctive appearance, as most of the leaf is occupied by a stout, very broad nerve.

 

 

Grimmia alpestris

ga
Col de Tende, Roya
At high altitudes in the Alps, this little grey Grimmia is a common sight, forming compact cushions on siliceous rocks.  It is visually and vegetatively indistinguishable from the almost-identical G.reflexidens (syn.G.sessitana) and fertile material must be collected to examine mature capsules microscopically - those of G.alpestris lack stomata.

This moisture-loving flush moss is described in the Bryophytes of the Queyras section of the site.

This occurrence in the Maritime Alps was my first encounter with Amblyodon, which is a very rare and seldom-seen moss in Britain.

 

 

Catascopium nigritum

ct
S of Col de la Bonette, Mercantour PN
Catascopium is a classic moss of base-rich, flushed ground, where its very distinctive, dark, horizontal capsules on long setae immediately draw attention to it.  No other moss resembles it in fruit.

Catascopium is widely recorded in the French Alps, although this site near Col de la Bonette remains the only place I have seen it.

Anomobryum concinnatum

ac
Col de Tende, Roya
Until recently, this species was considereda variety of A.julaceum.  These two mosses have a similar distribution in the French Alps, although A.julaceum has not been recorded as far south as the Maritime Alps.

A.concinnatum is distinguished by having a percurrent costa.

 

 

Bryum pallescens

bp

bp
Col de la Bonette, Mercantour PN
Bryum pallescens is a curious moss in the Alps, where it is a common species of montane rock ledges.  This is very different to its habitats in Britain, where it tends to be a casual weed of utterly unremarkable lowland habitats!

Microscopical characters of the mature capsules and fertile shoots are needed to identify this little species, as several very similar ones occur in similar habitats in the Alps.

B.pallescens is characterised by having appendiculate cilia on the inner peristome. It shares this feature with B.creberrimum, and the two are best separated by spore size - those of B.pallescens are larger (20+ microns), whereas those of B.creberrimum are between 10 and 14 microns. 

The visually similar B.algovicum has a different peristome structure which is immediately visible under a microscope.

 

 

Pohlia cruda

pc
Col de la Bonette, Mercantour PN
P. cruda is a very common species in many montane areas of Europe, as well as at lower altitudes.

I've described this species in more detail in the Mosses of Ben Lawers NNR section of the site.

 

 

Rhizomnium magnifolium

rm
Le Boreon, Mercantour PN
This moisture-loving species is quite widespread in the French Alps, despite being an extremely rare member of the genus in Britain.

Visually it resembles the very common R,punctatum, but the leaves are larger (hence the scientific name) and the stems bear micronemata (tiny, dark rhizoids which cover the stems).

The plants shown here were growing on a seeping, sheltered bank in larch forest, near the tree line with Sphagnum squarrosum.

In Britain, this attractive, small moss is very rare outside of the Scottish mountains. In the French Alps, it is more common but 'Mousses et Hepatiques des Alpes francaises' (Legland & Garraud, 2018) shows it as not observed in the Maritime Alps since 1990.  The colony shown here is almost certainly a new record.

I've described A.lapponicum in the Mosses of Ben Lawers NNR section of the site.

Pterigynandrum filiforme

pt

pt
Le Boreon, Mercantour PN
Pterigynandrum is a common moss in continental Europe, both on rocks at higher altitudes and as an epiphyte in Mediterranean regions.  It favours siliceous rocks, where it grows as loose wefts and patches with a slightly dingy greenish appearance.  It somewhat resembles Myurella species, but those tend to grow as paler, scattered shoots and have more rounded leaves without prorate cells.

I've described this species more in the Mosses of Ben Lawers NNR section of the site.

Lescuraea saxicola

ls
Le Boreon, Mercantour PN
I've only come across this attractive moss occasionally in my French travels - including on the very first rock I looked at!  L.saxicola is distinctive in having its leaves all curved n the same direction.  Microscopically, it has longer cells than the other common Lescuraeas and lacks pleated leaves.

L.saxicola is a great rarity in Britain, believed to have been extinct since the early 20th century.

 

 

Lescuraea radicosa

Val Gordolasque, Mercantour PN
Sanionia is one of the commonest pleurocarps in alpine meadows, where it thrives in sunny, short, calcareous turf.  It often occurs with Hypnum revolutum and Lescuraea species.

This species is described in the Mosses of Derbyshire section of the site.

 

 

Homalothecium lutescens

hl
Col de Tende, Roya
This common golden moss is a typical species of limestone terrain.  It closely resembles H.philippeanum, but that species has a nerve that reaches the leaf apex, rather than ending below it.  H.lutescens is very widespread in the French Alps but H.phlippeanum occurs widely as well.

This species is described in the Mosses of Derbyshire section of the site.

hl
 

Orthothecium intricatum

oi
below Col de la Bonette, Mercantour PN
This and O.rufescens are the only two members of the genus recorded from the Maritime Alps.  Given their reliance on damp habitats (especially the latter species), their occurrence is rather restricted - much of the limestone terrain in the Maritime Alps is too dry in summer for them to survive.

This species is described in the Mosses of Derbyshire section of the site.

 

 

Plagiothecium denticulatum ssp. obtusifolium
