It pays to wash your hands!

September was a month which saw lots of time being spent on bog cranberry plants and scratching the head as to which waxcap was I seeing. The cranberry (Vaccinium spp) checking began after I remembered botanist Andy saying my photos of a plant on Rannoch Moor in 2016 looked like it had hairs on the flower stem and this confirmed that I had found the rarer cranberry (Vaccinium oxycoccos) rather than the commoner species in our area, small cranberry (Vaccinium microcarpum).  As usual, cranberry checking started by accident as the list of ‘stuff’ in my diary for the 1st 
The brilliant bog
September reminded me.  I set out that day to look for a rare form of honey fungus that had been found a month earlier at RSPB Insh Marshes (Armillaria ectypa) in a brilliant bog area close to the Kincardine Church by the B970.  Once on the bog the first diary entry was for a collection of dead deergrass stems to see if there were any fungi present (Mollisia fuscoparaphysata) to help with Brian’s study down at Kew but as I bent down I could see something unusual popping out from the 
Bog jellydisc (Sarcoleotia turficola)

peaty pool.  Initially there was just one, a small round growth topped by a brownish cap and straight away I was thinking this was actually the wee fungus that grows in association with sphagnum moss and is known as the bog jellydisc (Sarcoleotia turficola).  As I searched around I found quite a few more fruiting bodies but then I noticed something else a bit unusual, stems of cross-leaved heath flowers (Erica tetralix) that were forming ‘circles’ rather than growing straight up.  There was also a small white ‘growth’ on the stem, close to the spiralling stem!  Some sort of gall?  Photos taken along with a couple of specimens which turned out to be Eriococcus devoniensis (heather scale bug) a member of the Hemiptera group of insects and it is the actions of these insects (sucking sap from the plant) that cause the plant stems to curl.  The NBN Atlas map shows just one record in the UK for this wee bug but Margaret Redfern confirmed my ID and also said that it was common in the UK but 
Cranberry leaves (Vaccinium spp) top and flowers bottom
seldom recorded.  This proved correct and I found it on all the other boggy areas I visited during the month.  I then stumbled on my first patch of cranberry and the wee light in my head asked “which species”?  Normally I just record all cranberry locally as small cranberry, but on this occasion, I decided to check if there were any hairs on the flower stem, and there were just a few so I thought if I take the flower head home, along with a bit of creeping stem and leaves, I should be able to check leaf size to confirm the species.  Wrong!  I can see entries in my diary going right through to the 20th September as I visited other bogs to check flowering stems and leaves to determine which species we were dealing with.  The simple guidance suggests if the leaves are widest near or below the middle and the flower stem (pedicel) is slightly hairy (pubescent) you have cranberry.  If the leaves are widest at the base and the flower stems are hairless (glabrous), then you have small cranberry.  However, the books also say that the flower stems of small cranberry are glabrous – or almost so – bringing in a little doubt into easy ID.  So, over the next few days leaves of cranberry plants were

brought back, along with a flower stem if present, and a selection of leaves were measured and photographed to see what developed.  With Andy’s help several were named, providing new local sites for the rarer Vaccinium oxycoccus, but also highlighting the fact that more work is needed to determine exactly which species is which and that, like me, folk further south shouldn’t just list cranberry, and folk further north list small cranberry, without at least making a few more checks.  The cranberry plants on the first day did though, produce something for which I’ve been looking for for a while, half red leaves, confirming the presence of the Exobasidium rostrupii fungus, a species with 
Bladderwort 'hairs' Utricularia stygia top & U. minor botton
less than 50 UK locations currently.  The diary list ended with an entry for bladderwort which, after checking the bladder hairs, turned out to be the northern bladderwort (Utricularia stygia).  At another bog site a collection of bladderwort plants confirmed that there were two species present, the northern plus lesser bladderwort (U. minor) but again only after checking the bladder hairs.  The latter species is one that may be found flowering occasionally locally but more regularly further west and north from my find location.  Here endeth the 1st of September!

The next day we had a nice family outing to support daughter Laura who was taking on her first 5K run in Huntly.  We were picked up by Ruth and the boys and on a gloriously sunny day we headed over to Aberdeenshire to visit a town where, as a youngster, I went with mum and dad to my uncle Robs wedding many decades ago.  We all met up about half an hour before the start and saw many of 
Laura at the start and completing the run.  Well done.
the competitors going through their warm up exercises.  The middle of the town was taken over with craft stalls, food outlets and a farmers market and after we waved Laura off we took the opportunity to grab a quick bite to eat especially for the boys who’d had quite an early breakfast.  There was just too much to choose from but eventually sausage butties, chips and other goodies were bought and everything was finished just in time to get to the finish line to cheer Laura home after half an hour of running.  Well done.  Just time for a walk round the craft stalls and the local charity shops before heading back over the tops to Dufftown and on to Strathspey.

A phone call from farmer Hugh on the 4th caused a bit of excitement, he had seen a couple of red kites whilst bailing hay the day before and, as he spoke, he confirmed they had just re-appeared overhead.  Cameras quickly assembled and off I went to Boat of Garten to see if I could catch up with what is, quite a rare visitor locally.  As I pulled off the road into one of the hay fields I saw the first kite straight away followed by a second a few minutes later.  Taking photographs of the birds against 
Local red kites including a tagged one
the sky was difficult to see if the birds were carrying any tags and when I saw them land on some of the round bales in the next field, I drove along the road to get a better view.  Of the two birds in view I could see one was tagged so I tried to get as good a photo as possible to hopefully read the details later.  Being parked on the road verge wasn’t the safest place to be so I drove on to one of the farm tracks and looking back at the birds and the hay bales I could see that there were three kites but just the one with wing tags.  A bit of a battle with rooks ensued and two kites disappeared up into the woods before it was time for me to head off to pick up the boys from school.  On the way back from school we drove past the field with the bales but didn’t see any sign of the kites and Hugh confirmed that they had moved off later that day.  The birds appeared at the time the hay was cut, and Hugh told me that lots of insects and small mammals are killed or injured during the cutting and baling process and that is probably what had attracted them in initially.  The tagged bird was from the Beauly Firth and was tagged in 2015.  Was this a family group?  Might they have bred nearby?  It will be interesting to see if there are any more reports of sightings and even more interesting if any are seen at the start of the next breeding season.

If the cranberry plant checking accounted for quite a bit of time re site visits and leaf checking this month, a visit to the ex Boy’s Brigade field at Carrbridge started off another.  For many years this field was used as an annual camp location but, whether the agreement to use the site ended or the 
Protesters in March 2015 top and the stubble turnips
after the important Boy's Brigade field was ploughed up
Brigade found another site with modern facilities I don’t know, but in recent years I had got to know the site because of the species losses that would occur if the plan for new housing was successful.  Over the years a list of locally rare grassland fungi and plants (orchids mainly) had shown this field was something special probably due to it never having been ploughed or heavily fertilised.  When the last planning application was made in March 2015 by Inverness-based developer Tulloch Homes for 72 houses for the site, with an additional 24 close by, over one hundred protesting locals were on site when the developer and Cairngorms National Park planners and Board members made their site visit to decide whether to allow or turn down the application.  On this occasion it was turned down.  
Hygrocybe punicea waxcap now lost from BB field
However, on the BB field things were slowly changing and encroachment by increasing numbers of cattle was having more and more of an impact despite the Park Board knowing of its natural history importance.  The final nails were firmly nailed into the coffin this summer when the developer told the tenant farmer to plough it up!  So, instead of waxcaps, rare coral fungi and orchids the site is now a wall to wall field of stubble turnips and the important site has now been lost forever all on the whim of a local developer.  You don’t need planning permission to destroy an ecologically important site in the Cairngorms National Park and, despite all the information provided about the species present at the time of the planning application, no safeguards were put in place by the Park to ensure its survival.  I doubt they even know it’s gone!  The last week of September saw me start checking a few other locally important unimproved grassland sites, just to try and build up a picture of what was supported by those that remained.  The first site was the field just at the end of our road, known 
Shaggy inkcaps, fresh (top) and deliquescing inky spores (bottom)
locally as the ‘pony field’ and a location turned down for housing just a few years ago.  However, waxcaps are not the easiest group of fungi to identify so a visit of a few hours often meant many hours of checking via the microscope, especially when dealing with a group I’ve had little experience in.  On the way to the pony field I stopped at Ross’s house to photograph an amazing display of shaggy inkcaps/lawyer’s wigs (Coprinus comatus) with everything from newly emerging through to the last drips of ‘ink’ (spores) as the edges of the curled-up cap.  In all, there were about 50 fruiting bodies a few more than the 4 that popped up in 2016.  After about four hours in the field I had 20 entries in my diary comprising ten species of spindles or waxcaps with once again the crimson waxcap (Hygrocybe punicea) being the biggest and most showy.  Three new species were recorded 
Smoky spindles (top) and white spindles (bottom)
for the site; smoky spindles (Clavaria fumosa), white spindles (Clavaria vermicularis) and parrot waxcap (Hygrocybe psittacine) adding to the 12 species recorded by fungus expert Liz Holden in 2010.  However, a return visit the next day to finish off the field saw yet more species added with handsome club (Clavulinopsis laeticolor) and vermilion waxcap (Hygrocybe miniate) probably putting this field into the very important category nationally. 

A quick visit to the Flowerfield orchid site also turned up a few species along with an unusual beetle Galeruca tanaceti (a female) which feeds on yarrow and other composites and with few Scottish records. The site though that has seen the most time and effort has been the edge of the proposed 1500 houses at An Camus Mor where a small strip of grassland has produced lots of goodies.  An email alerted me to the fact that there were a lot of earth tongues growing, another group of fungi

indicating an unimproved grassland site, along with several waxcaps.  A site visit the next day showed that there were 10’s of earth tongues along with 5 different species of spindle and 5 waxcaps, and this is where the fun started.  There is a very good book to help with identifying waxcaps ‘The Genus Hygrocybe by David Boertmann’ but when it comes to earth tongues there isn’t yet a ‘one stop shop’ detailing all the species, but this only became clear once I’d taken a specimen home, checked the spores, and then delved into various website to try and match the specimen to a species.  One

(x1000 oil) from a cross-section of earth tongue stem
species that wasn’t too difficult to name was the white fungus growing on many of the earth tongues (Hypomyces papulaspora) but the amazing sight that greeted me down the microscope re the earth tongue was, once again, going to take me down a long road to try and ensure the right name was given to the species found.  Brian at Kew offered some guidance and suggesting details were recorded covering the general appearance of the fungus, the size of the spores and the number of ‘divisions’ (septa) within the spores along with the shape of the ‘paraphyses’ hair-like structures growing between the sacs holding the spores.  The carrot that was also dangled was that there are probably species out there that could be new to the British list.  It took a little while to get properly organised and, as more and more earth tongue were found, everything was listed on a post-it and between 10 and 20 spores measured and the septa counted.  Each specimen took about an hour to 
The broad damsel bug (Nabis flavomarginatus)
check and, as September ended, more sites were still being found. It was obvious that another wee project was developing.  Watch this space.  At one site a wee bug landed on my GPS and stayed just long enough to have its photo taken and between the British Bugs website and invert expert Stephen, the name Nabis flavomarginatus the broad damsel bug was arrived at.

Mid-month I managed to make my trip over to Deeside to check on only the second known UK site for Bankera violascens.  The Morayshire site had done us proud (August Blog) so I had high hopes of a decent count at the original site.  As with the August site, the tooth fungus is growing in association with Sitka spruce, a non-native, and the main reason why the fungus, despite it rarity, doesn’t receive any conservation status designations.  At the site I found the grey tooth (Phellodon melaleucus) and Sistotrema confluens but not a single Bankera!  Perhaps it had been a dry summer on Deeside so I 
Mealy tooth (Hydnellum ferrugineum)
thought I should check another regular tooth fungus site near the River Dee.  The first surprise that greeted me was a group of seven scaly tooth fungi (Sarcodon squamosus) all the size of dinner plates, the biggest measuring 300mm across its cap.  Past records show that I’ve had three fruiting bodies here previously but with no mention of great size.  Lots of mealy tooth (Hydnellum ferrugineum) were present with a couple of last year’s fruiting bodies covered with another fungus, Collybia cirrata.  With plenty of tooth fungi here it was unlikely that this had been a dry summer so a little strange why there were no Bankera at the first site.  As I reached the end of the population of mealy tooth I spotted something that got me a little excited, definitely nothing to do with showiness or colour, but a drab brownish Boletus like fungus, about 10cm diameter, but growing so close to the 
Boletopsis perplexa, as found (top), underside (middle) showing pores
and spores (bottom) x1000 oil
ground it wasn’t possible to see below the cap.  If my hunch was correct, this wasn’t a species to collect so I carefully cut a section of cap away leaving most of the cap and stem in place and as I turned the cap over I could see a pored fertile surface, similar to a Boletus but with the pores of a different shape.  I was 90% certain that I was looking at Boletopsis perplexa a species I had seen close to here in the past but with very few records from the UK.  It is a fungus associated with pines and is part of the Bankera (tooth) fungus family rather than Boletus.  Once home there were just 
The 'giant' Sarcodons
about enough pores to hopefully produce spores and when I checked the next day I knew 100% that this was the Boletopsis.  This is just the thirteenth UK record.  The first was in 1876 but was mis-identified and with six recent records all coming from the same location about 10 miles from my find, this was a species with few UK locations.  My part specimen and glass slide covered in spores is now deposited at Kew.  An odd plant turned out to be northern bedstraw, and, with a northerly wind blowing, the first pinkfeet of the year passed overhead.

Whilst visiting a bog to check cranberry leaves I found a small population of destroying angel fungus and took a sample home (very carefully) to check.  Somewhere along the way I must have licked my spore laden fingers and had a slightly upset tummy for a day.  If trying to self-harm once wasn’t bad enough a day out in Nairn also posed a problem.  It was a lovely sunny day, lunch was taken at a nice local food stop and we then walked down towards the harbour.  Following the River Nairn, we 
River Nairn swans
stopped to watch a pair of mute swans trying to ‘hide’ and whilst taking their photo I thought I had found a group of small nettles (Urtica urens).  Whilst investigating I also noticed an unusual yellow flower which Janet suggested was the same as we had seen on our visit to Edinburgh way back in May.  Not convinced I took a sample to check once home.  As we walked along with samples of nettle and yellow plant in hand I noticed my fingers had been stained orange and I assumed I had come into contact with a leaf fungus somewhere.  Once home I got the plant book out and was working my way through the pages first to confirm I had just the common nettle (Urtica dioica), but was having trouble naming the yellow plant.  Flicking through ID books I have a habit of occasionally licking my fingers to help with page turning and as my bottom lip started to tingle I didn’t realise how grateful I should have been to Janet who had also been checking out the yellow 
Greater celandine (Chelidonium majus)
flower.  “I told you it was the same as the Edinburgh plant” she informed me and as we read through the description of greater celandine (Chelidonium majus) it informed us that “the stem is sparsely hairy, producing bright orange latex when cut”.  The cause of my orange fingers!  The plant description also told us “Introduced, and cultivated for medicinal purposes, but the whole plant is very poisonous.”  Time to give my hands a good wash and to swill out my mouth with clean water which thankfully stopped the tingling lip!  There were no further symptoms, thankfully.

At the start of the current breeding season a new project was initiated aimed at improving the conservation fortunes of six of the rarer invertebrates living within the Cairngorms National Park.  Gabrielle Flinn was employed as the Projects Officer and was based at the RSPBs Abernethy Reserve.  We eventually met up after the orchid count at Flowerfield Meadow and I was asked if I could help with a training day linked to one of the six, the shining guest ant.  The 23rd September

Success!
was the date chosen so all I had to do was find a shining guest ant for the attendees to see!  So, through late August I paid regular visits to wood ant nests where I had seen the ant previously and was hugely relieved when, early in the month I managed to find a nest with guest ant in residence.  Three days before the event I saw two guest ants on the nest so it was fingers crossed that they would be visible on the day.  The 23rd dawned very cold with almost a frost, a little worrying when the guest ant only seems to be active when the wood ants are out and about, but by 11am the sun was up.  The training day started with a visit to two big ant nests in Garten Wood so Gabrielle could explain the workings of the ants and the nest, but we failed to find any guests.  Introductions over we headed round to Tulloch to the occupied nest and, as I crouched down by the nest I managed to see a guest ant.  Slowly, the trainees came to the nest and amazingly, despite the tiny size of the guest ant when compared to the wood ants, everyone managed to see one.  In fact, as we watched we saw up to three guests wandering around the top of the nest.  The nest we were watching was just one of about 6 small nests at that site and as everyone spread out to watch their own nest, there were shouts of “I’ve got one” from four of the six nests which was something similar to what I had found a couple of years ago.  An excellent outcome and I await with interest news of new finds.  The link below gives more details about the project and the species involved.

What an amazing late summer for red admirals.  During August I had quite a few diary entries for red admiral.  Similarly, for early September.  An email though on the 20th alerted me to someone locally having 6 in his garden followed a few days later with a count of 20 then a count of 45 with the butterflies feeding mainly on Michaelmas daisies.  Our own garden was also doing well; 6 regularly 
feeding on the flowering kale plants in the veg patch and there were up to 10 on a buddleia bush just down the road.  Why?  It would appear that over the last few years the numbers of red admirals now residing in England has been increasing and some of these must be ‘migrating’ north into Scotland.  A very timely programme also popped up on BBC Radio 4 where a repeat of a Living World programme, first broadcast in 2008 explained quite a bit about what is happening, even then.  During the summer, Butterfly Conservation staff have been finding red admiral caterpillars locally, showing the butterfly must be arriving early in the summer before getting down to breeding.  One to watch into the future.

Raigmore Hospital visit on 13th and Dr. Soh is very happy with the blood tests results following the radiotherapy treatment, PSA down by two-thirds.

That’s it for another month, hope you enjoyed the read.
