It was an eventful early morning as we had late notification that the Borrowdale road from Keswick was closed. I made an extra-early start from home and took the narrow and very winding route via Buttermere. Reaching Newlands Hause, I found the first few metres of the descent into Buttermere valley was very icy, with what looked like a covering of snow on the road, but beyond that it was fine and I made the descent safely. Arriving at the Seatoller National Trust car park I found that the road was not in fact closed, and most people had arrived via Borrowdale, which was probably just as well. We walked a short distance down the Seathwaite road, crossing the bridge and immediately taking a gate into the woodland. As the woods have been quite extensively surveyed, we decided not to do a full species list, but just check the species noted in Ben Averis’s report, and any additional species of interest. As there were a couple of beginners or near beginners in the group, we started by looking at some common species and explaining some of the basics of bryophyte identification. Andy McLay soon joined us, having been notified that the road closure was a false alarm.

We started by looking at some rock faces near the north edge of the woodland. There was plenty of Saccogyna viticulosa, and a few cushions of Rhabdoweisia crenulata, the teeth at the tip of the leaf just about visible through a hand lens. Lower down the north-facing side of the outcrop there was some Plagiochila spinulosa. Sloping rocks had plenty of Hageniella micans, sometimes more green than the typical golden colour, and this species would prove to be abundant across the north end of the site, despite being nationally quite scarce. We soon found some small patches of Harpanthus scutatus, standing out with its vivid green colour. Bazzania trilobata started to appear on small boulders. One such boulder had some nice Orthocaulis attenuatus, the pale tips of its shoots (with immature pale green gemmae) visible through a mat of Dicranella heteromalla, while nearby there were shoots with more mature red gemmae.

At NY244137 was a large rotting log which proved an excellent habitat for some interesting species, including Dicranodontium denudatum, Scapania umbrosa, Lophozia incisa, Cephalozia curvifolia, and a couple of small patches of Harpanthus scutatus. Andy took a small sample of Cephalozia, which he thought might be C. catenulata (found here by Ben Averis in 2010). Unfortunately he found no fertile material and was unable to confirm this species. We thought we could see tiny red shoot tips through the Cephalozia, and hoped this might be Anastrophyllum hellerianum, but this was perhaps wishful thinking.

We had pinpointed a couple of sites where Adelanthus decipiens had been recorded in 2010, but were unable to refind it. Likely looking boulders were covered in Rhytidiadelphus loreus, and we wondered whether nitrogen enrichment was favouring the growth of this species to the detriment of rarer liverworts. During the lunchbreak near the northwest corner of the woodland, a patch of Anastrepta orcadensis was found on a boulder near the flush heading down to the wall, as well as some Mylia taylorii. Heading south and uphill we followed the wall through some large boulders. Here there was much more Mylia taylorii, forming lovely fat cushions, and quite good-sized, healthy looking patches of Bazzania tricrenata. Reaching the top of the ridge, which was rather dry, we headed south, away from the bend in the wall, down into a bit of a boulder field. Adelanthus decipiens had been recorded on the north face of an outcrop, so we scoured all the outcrops we could find, to no avail. Reaching a flush and beck at around NY243135, we did however find abundant Radula voluta in healthy mats on stones in and around the water. There was also a patch of Pseudohygrohypnum which turned out to be the rarer species, P. subeugyrium (confirmed by Tom Blockeel).

Further up the slope, Paul found a nice patch of Odontoschisma denudatum, with its pale gemmiferous tips.

Heading back up the slope towards the west wall, we reached an area of very large boulders and outcrops. Near here Richard found the first patch of Ptilium crista-castrensis, while Paul found a very distinctive patch of Lepidozia Pearsonii, its thin, threadlike shoots looking distinctly different to the commoner Lepidozia reptans. The outcrops had good cushions of Mylia taylorii and more Rhabdoweisia crenulata, as well as several cushions of Plagiochila punctata, but no Adelanthus decipiens and no Herbertus hutchinsiae. We wondered whether the fairly dry conditions, which left many liverworts looking a bit crisped, was making it hard to spot things.

The light was starting to fade as we headed back downhill, and we decided to call it a day as visibility was becoming so poor. We returned towards the northern gate, following the contours below the steeper, rockier sections of the hillside. We passed a lovely, larger patch of Ptilium crista castrensis but didn’t see any new species on the return journey.

It had been a productive day and we’d seen lots of lovely species, some in surprising abundance. We were a little concerned about the species we had failed to re-find, and felt that it would be good to have a return visit to explore the lower section of Low Stile Wood, and perhaps High Stile Wood or the woodland south of Low Stile wood.

The January meet fell on a particularly sunny, and comparatively warm, day with only the slushy roads, and snow on the distant hills, hinting at the wintery conditions of the past few weeks. Another great turn out included a mix of experienced and newer learners, keen to expand their knowledge. We met by Haweswater and took a short walk along the road into Naddle Forest where we would spend the day. The woods are a great example of ancient relic forest, boasting a wealth of lichen and bryophyte species.

The Bryologists soon peeled off, climbing the steep slopes to examine a rock face which presented a good range of mosses and liverworts. A few common woodland species were quickly ticked off: Cirriphyllum piliferum, Hylocomiadelphus triquetrus and Rhytidiadelphus loreus. As represented by these first few species, there was a mixture of acid and calcareous species to be found throughout the site, hinting at the habitat mosaic.

Such a rich assemblage provided a good opportunity to compare some common pleurocarps. Paul gave a useful explanation of the differences between Loeskeobryum brevirostre, Hylocomiastrum umbratum and Hylocomium splendens. Although they are all large, red-stemmed pleurocarps, Hylocomium splendens is the most regularly branched of the three and has oval stem leaves with a long, tapering tip. The stem leaves of Hylocomiastrum umbratum and Loeskeobryum brevirostre are broadly triangular, but H. umbratum leaves are heavily pleated, distinguishing it from L. brevirostre which is a larger moss, and its leaves stick out, giving it a chaffy appearance.

With our heads now thoroughly in bryophyte mode, we moved upwards and came across the first of four Plagiochila species to be found; Plagiochila asplenoides. As the largest of the Plagiochila species, it clearly displays the characteristic convex, translucent leaves. After recording P. porelloides, which you could be fooled into thinking is simply a smaller version of P. asplenoides, we found our third species: P. spinulosa, which is an excellent example of an Oceanic indicator. Quick to differentiate from earlier species by the irregular teeth at the tip and back margin of the leaf, it bears more resemblance to our fourth species (read on!).

Another oceanic indicator was soon happened-upon, identified by its slightly untidy appearance and yellow-brownish colour: Scapania gracilis. These species like dry, sheltered areas within high rainfall habitats. Protected from temperature and weather extremes, S. gracilis thrives in these humid, acidic habitats. A less common oceanic indicator is Anastrepta orcadensis, so we were excited to find some quite large patches of this; surprisingly, we didn’t come across any more in the rest of the day.

After lunch we continued uphill and inadvertently split up into a few smaller groups to explore the crags and deadwood that littered the area. The habitat here was very similar to the morning, and the trees heralded woodland classics such as Frullania dilatata and Frullania tamarisci, two epiphytes that can be separated based on their growth form (appressed to trunk versus forming loose wefts) and their lobule shapes (helmet shaped versus small/long). While the area may not be considered as oceanic as some of the traditional oak woodlands in the western lakes, many interesting species continued to make their appearance. From the lovely looking Lophozia ventriculosa with green-gemmae-tipped bilobed leaves to the tiny, rusty coloured deadwood species Cephalozia curvifolia (previously Nowellia curvifolia), our list continued to grow at a rapid rate from relatively few micro-habitats.

Of particular interest was Schistochilopsis incisa found growing out of a heavily decaying log, (yet) another liverwort that forms a zag-zag pattern of jagged bi-lobed leaves on wet peats and decaying materials. In the same habitat was Riccardia palmata, growing profusely, and small amounts of Scapania umbrosa, the commonest of the ‘small’ Scapania species. This can be easily identified by the pale green to brownish colour and bright red gemmae present – but this proved challenging on the day as most had washed away in the rainy Cumbria weather!

As we climbed higher still up the slopes, we were able to regroup for a chat (and snack) around a calcareous woodland flush where the final push for species was revitalised by the change in habitat. Always great to find, Ptilium crista-castrensis (Ostrich plume feather moss) poked its feathers out from around a rock and on the damper ground around the flushes were ample patches of Hookeria lucens, a lovely liverwort-like moss with flattened, shiny leaves, and Fissidens dubius, a species easily distinguished from other Fissidens by its larger size and pale leaf margins.

With daylight fading fast on our steep north-facing slope, a last push into the crags by Kerry and Paul found Spinulosa punctata, Frullania fragilifolia and Bazzania tricrenata, all great indicators of oceanic climate and conveniently positioned close to the community associate Hymenophyllum wilsonii (Wilson’s filmy fern). So, while there are those that might tell you Haweswater isn’t ‘oceanic’ enough for a good moss hunt, here’s hoping our discoveries might convince you otherwise! Thanks to everyone that attended, and we look forward to seeing you all again in February.

Our December meet took place on a drizzly but mild December day at Black Beck Woods, an area of privately owned conservation woodland in the south lakes near Bouth (previously owned by the ‘Booth’ family in fact!). Due to the size of the site, we initially met just off the A590 to then travel in fewer vehicles along the smaller roads and access tracks to the starting location. We saw a record-breaking number of group members attend, meaning Kerry had the tricky logistical job of herding 20+ bryologists and lichenologists into cars so that we could get started in a timely fashion.

Black Beck woods is owned by Edward Mills, a woodland manager with a keen interest in using practical conservation and restoration methods to create a high-quality woodland in the temperate rainforest zone. Ed gave us a great introduction to the site and provided a plan for the day so that the group could prioritise visits to the most interesting parts of the woodland.

This was a rare occasion where the bryophyte and lichen groups stayed within view for much of the day, ambling up the woody slope from the access path to find our respective treasures. While Paul gave a beginner’s group an invaluable introduction to common acid species such as Pseudoscleropodium purum and Polytrichum formosum, others set out in hopeful anticipation of the oceanic indicator species found in many similar sites in the area. To our joy, we were able to quickly locate sizable patches of Bazzania trilobata alongside regular findings of associates Plagiochila spinulosa and Saccogyna viticulosa, all great indicators of healthier oceanic woodland.  

We headed through the woodland to a locally known ravine called ‘Scholar’s Gap’, a perfect damp, shaded rocky habitat for humid-loving species with locally rare Tilia cordata (Small Leaved Lime) growing from the crags. Here we discovered many of the same oceanic indicators (a good sign of a consistently high-quality site), as well as some wonderful hummocks of Leucobryum glaucum poking out between the rocks. The find of the morning, however, was of course Andy’s delightful discovery of Syzygiella autumnalis (previously known as Jamesoniella autumnalis) on a shaded rockface right at the bottom of the ravine slope.

We were able to meet up with the Lichen group for lunch, enjoying a chat about morning finds along the banks of the Rusland Pool at the southeastern side of the site. The afternoon saw us exploring a willow carr at the south end of the site, just off the public footpath at Fish House Bridge. Although we were still close to the craggy acid woodland from the morning, this wet woodland habitat provides very different conditions for new species discoveries. The flushing of water brings in a more base-rich influence, meaning common indicator species such as Calliergonella cuspidata and Sphagnum auriculatum started to appear. There were also many epiphytes within ID availability on the sprawling willows, and those with wellies were able to access species such as Frullania tamarsicum, Bryoerythrophyllum recurvirostrum, and Neckera crispa. Between the trees on the boggy woodland floor, Sue’s keen eyes spotted the shiny leaves of Hookeria lucens, a lovely flat-leaved moss that impersonates a liverwort at first glance.

The site sports a well-maintained boardwalk to host the public right of way, allowing us good access to the more inundated areas and perfect habitat for Trichocolea tomentella, the wonderfully named ‘Handsome Woollywort’ that was growing in abundant tussocks in perfect view. These wet areas were also great for Sphagnum, and our finalcount totalled at eight,which shows great diversity at the site.

While the day was already overflowing with species, there was one habitat we were yet to explore: deadwood! Luckily for us, there were conveniently placed logs all along the boardwalk that finally allowed us to tick off some classic deadwood species such as Odontoschisma denudatum, Cephalozia lunulifolia and Lophozia ventricosa.

Overall, the site turned out to be full of surprises, and although it currently has no SSSI designation there is hope that recording such as ours can start to create a better picture of the quality of the site in the future. Thanks to everyone that attended and to Kerry and Ed for organising the day. See you in January and happy holidays to all those who celebrate!

We started the field meeting at a small lay-by in Legburthwaite with a good turnout of around 10 bryologists. A last-minute illness meant our group lead was unfortunately unable to attend, but we still set off up the trail to High Rigg with a hopeful outlook on a drizzly but mild November day.

A brief hike up the path to Wren Crag brought us into monad NY3120 where we started our species recording on a rocky slope, finding many common upland species including Polytrichum alpinum, Orthocaulis floerkei, and Pogonatum urnigerum. There were signs of oceanic climate indicators in the rocky outcrops and sheltered crevices, particularly the liverworts Scapania gracilis and the more restricted Orthocaulis atlantica, distinguished from the aforementioned O. floerkei by the presence of red gemmae. Other liverworts here included both Lophozia excisa (with red gemmae and abundant perianths) and Lophozia sudetica (with many brownish gemmae and eroded leaves on gemmiferous shoots). The moss Leptodontium flexifolium caused some confusion. It looked rather like a Pohlia and was only identified under the microscope from its very papillose cells and large marginal teeth. It occurred in two forms in two different locations on the site: one small, looking rather like a Barbula species, and the other with more drawn-out shoots and deciduous bulbiform branchlets looking rather like Pohlia bulbils. It is fairly common in such acid habitats as this but we may be tending to overlook it as a Barbula.  

After an ambling climb uphill, we decided to pick up the pace and push further into the centre of the monad towards some promising mires and pools surrounding the High Rigg trail. While many distracting crags were found along the way, the wet heaths provided some great common acid indicator species such as Pleurozium schreberi and Hylocomium splendens. As we headed down into the mire, the species composition suggested a base enrichment entering via the springs and flushes in the area, and the Sphagnum species composition highlighted this variance nicely. The group quickly totalled up thirteen species of sphagnum, including Sphagnum russowii, S. girgensohnii, and S. auriculatum in good numbers in the base-enriched areas. The base influence was also supported by further discoveries of Calliergon giganteum around a pool and Hypnum cupressiforme var. lacunosum appearing on the surrounding slopes and scree.

After a quick stop for lunch the group decided to head back down the path to enter the monad from a lower location via a riverside path. Here a few of our members parted ways and a smaller group headed out to explore the lightly wooded scree slopes on the east-facing side of Wren Crag.

The find of the day was Ptilium crista-castrensis which appeared in surprisingly large numbers across the slope, with several well-established patches discovered during the afternoon. Spirits were further raised by the discovery of the western species Frullania fragifolia, an almost-black liverwort that lives up to its name; the fragile leaves practically fall off in your hands!

Overall, we recorded 107 species of bryophyte, and the site provided a good variety of different habitats to reinforce upland species learning. With many beginners on this trip, it provided a great opportunity for knowledge sharing and conversations around how and why our species form different distributions in the uplands and in microhabitats. Thanks to everyone that attended and contributed to species recording!

A small group (Clare Shaw, Kerry Milligan, Paul Ross, Judith Allinson, David Shaw) met at a parking layby on Leck Fell, just before Leck Fell House. We then trekked down the fell towards the beck, through deep heather and bracken, aiming for the less steep access point upstream of Ease Gill Kirk. The stream bed was totally dry, as the area is limestone and full of pot holes and sink holes, so the water drains away for long stretches.

In the overhand of a bank above the beck, Paul found a lovely patch of very fertile Seligeria recurvata, which we all admired. Rocks in and by the beck had Barbilophozia barbata and Barbilophozia atlantica with its distinctive red gemmae. A Grimmia growing on limestone, which seemed a candidate for G. dissimulata, turned out to be G. trichophylla.

We descended the beck into Ease Gill Kirk. Wet rock faces had abundant Chiloscyphus polyanthos, while a large boulder in the beck had Encalypta vulgaris (sadly without capsules) and a reddish Mnium marginatum.

A rock face and steep slope above the beck just upstream of Ease Gill Kirk had Marchesinia Mackai and Orthothecium intricatum, with Gymnostomum aeruginosum and Trichostomum crispulum and T. brachydontium at the base.

Judith and I left after lunch for the long-seeming trek back to the car across the difficult ground, but now with a steep uphill gradient to contend with.

After lunch a few more species were added to the list, including Dicranella rufescens and Metzgeria pubescens, adding up to a very respectable 98 species altogether.

Peter Bullard and I met up with a larger group of lichenologists for our field trip to Alcock Tarn. Parking in free parking areas in quarries on the minor road above the A592, we walked up the road and were soon climbing in sunshine on a good track. Alcock Tarn is at the far end of the monad, so we had a whole monad of footpath and surrounding areas to record in a single recording sheet, always something of a relief. We soon stopped to admire lichens and bryophytes on small rock faces by the track, including Bryum capillare, Orthocaulis floerkei, Andreaea rupestris, Racomitrium fasciculare and Racomitrium heterostichum. The track itself had good quantities of Polytrichum piliferum, with its distinctive hyaline hair point, and small Oligotrichum hercyanum, quite a common moss but restricted to acid soils in upland districts, where it is often seen on footpaths and tracks. Always lovely to see, it is clearly recognisable under a hand lens by its frilled ruff of wavy ridges (lamellae), often hiding within the inrolled margins of the leaf. In the same family, we later found Pogonatum aloides and Pogonatum urnigerum, which was a good opportunity to compare the features of the different species.

The lichenologists were having a lengthy tutorial session, so Peter and I decided to move on up the track. We found further boulders and rock faces, with an interesting small, dark Marsupella emarginata, which we speculated might be var pearsonii. Sadly, later examination suggested that the commoner (even ubiquitous) var. emarginata was more likely, as the pigment was dark brown without clearly reddish tints, and there was no sign of any apiculate lobes. The same rock did however have a nice example of Scapania compacta and Andreaea rothii.

Higher up, the path crossed a small beck which provided some good bryophyte habitats. Where the beck went under the bridge there was plenty of golden Sciuro-hypnum plumosum, Hygrohypnum luridum with abundant sporophytes and Rhynchostegium riparioides. Further down the beck was Chiloscyphus polyanthos s.l. a lovely patch of shiny Bryum julaceum on a rock, while an old tree had Lejeunea lamacerina, Metzgeria furcata and Frullania dilatata. At this point we were joined by Georgia Stephens, the new Rainforest advisor with Plantlife, who had come to learn more about bryophytes in the region, so we ran through some of our finds and headed up to the tarn, where we stopped for lunch.

The tarn was enlarged in the 19^th century with a stone and earth dam and has a fair amount of infrastructure, including a concrete outlet. This had abundant golden Sciuro-hypnum plumosum, while in the wetter parts at the base we found Dichodontium flavescens, Pellia epiphylla, Conocephalum conicum, and a small Fissidens which turned out to be Fissidens bryoides. There was a boggy area around beck exiting the tarn, which we scoured for Sphagnum. We eventually found a few patches by the beck, and went through the Sphagnum Field Guide key, identifying S. palustre, S. rubellum and S. subnitens, growing with Aulacomnium palustre. Among the hummocks of molinia we also found Calypogeia arguta and Plagiomnium elatum.

The afternoon was wearing on so we headed back to the car, meeting some lichenologists on the way. We didn’t have a very long list, but we’d had a very pleasant afternoon and done a lot of useful revision and consolidation!
