Mnium stellare Hedw.

Part of a leaf of Mnium stellare (Starry thyme-moss) under a high power microscope. It is starting to show the blue colouration of the cells, typical of this species when the cells die.

Hookeria lucens (Hedw.) Sm.

Hookeria lucens (Shining Hookeria), on the Gower Peninsula in May 2019.
It's always a pleasure to find this moss, often shining out from a shady woodland bank, or a dark crevice in a cliff face.

Chiloscyphus polyanthos (L.) Corda*

Chiloscyphus polyanthos/pallescens (St Winifrid's Moss), on a rock in a stream in the Brecon Beacons, July 2020.
*Not identifiable with certainty without perianths, but the habitat and appearance suggest C. polyanthos in this case.

Sphagnum subnitens var. subnitens Russow & Warnst.

Fruiting Sphagnum subnitens (Lustrous Bog-moss), near the almost unpronounceable Bwlch in the Brecon Beacons, June 2020. Capsules are common with this species, but no less beautiful for that.

Philonotis fontana (Hedw.) Brid.

Philonotis fontana (Fountain Apple-moss), June 2020 in the Brecon Beacons.

In this area, Philonotis fontana often seems to develop this branching at the shoot tips in late spring / summer.
Presumably these are deciduous branchlets used for reproduction, as they are not visible later in the year so must have broken off and dispersed.

Sphagnum subnitens var. subnitens Russow & Warnst.


Sphagnum subnitens
Sphagnum subnitens var. subnitens branch leaves under the microscope. On the left, the concave surface showing widely exposed chlorocysts and large pores. On the right, the convex surface showing narrowly exposed chlorocysts and small pores. Care must be taken in the latter not to focus down onto the larger pores in the concave surface.
Stained with methylene blue.

Tortella fasciculata (Culm.) Culm. ex J.J. Amann

Tortella fasciculata
Tortella fasciculata with capsules, found and photographed by Peter Martin at Craig Cerrig-Gleisiad, vc42 in March 2020.
This is only second fruiting record of this species, the first being by R. Hall in 1951 on a wall by Lochan-na-Lairig in vc88.

Moerckia hibernica (Hook.) Gottsche

Moerckia hibernica (Irish Ruffwort)
Here is an image of female plants of Moerckia hibernica photographed on the ridge north of Sron Chona Choirean, Stuchd an Lochain, Perthshire on 17 September 2019, in a Sphagnum-dominated flush at 810 m, in a site where it was first discovered on the Killin BBS meeting in 2014.
M. hibernica is much less common than its relative M. flotowiana being found in neutral Sphagnum-dominated flushes, whereas the latter prefers much richer fen and dune slack habitats.

Marchantia polymorpha subsp. montivagans Bischl. & Boisselier

Marchantia polymorpha subsp. montivagans
The relatively rare cousin of the Common liverwort, Marchantia polymorpha subsp. ruderalis which is found in gardens throughout the UK. Note the absence of a black median line, present in both other subspecies. Subsp. montivagans is characteristic of base-rich springs and flushes.
