Sphagnum subnitens var. subnitens branch leaves under the microscope. This post shows the concave surface of the leaf with widely exposed chlorocysts and large pores. The next post shows the convex surface. Stained with methylene blue.
Sphagnum subnitens var. subnitens branch leaves under the microscope. The convex surface has narrowly exposed chlorocysts and small pores. Care must be taken not to focus down onto the larger pores in the concave surface. The previous post shows the concave surface view. Stained with methylene blue.
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.
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.
Female plants of Moerckia hibernica (Irish Ruffwort) 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.
This is 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. Photographed near Mynydd Llangattock, VC42 in February 2020.
Reboulia hemisphaerica (Hemisphaeric liverwort or Purple fringed liverwort) with friends, including Riccia sorocarpa.
Pterogonium gracile (Bird’s-foot Wing-moss). Understated elegance - surely deserves a better common name than this! Photo: Jo Denyer, on the Kerry Summer meeting 2019
A non-English bryophyte for a change. Captured by Peter Martin in Greece (under the pretence of visiting his daughter).
