A new species of fungi for the Thorne Moors list?

December 7, 2017

Wednesday 29 November started out cold (4 degrees C) but sunny and bright.  The afternoon saw a couple of intermittent showers.  But otherwise and dressed like an onion, it was one of those days when it’s great to be outdoors and rummaging about in carr woodland looking for things of natural history interest.

The woodland floor was a quagmire and very wet in places, particularly where deer had passed through and churned up the mud. Not to be deterred, using the faithful thumb stick as a very useful tool to test the ground ahead and pushing aside with ease bramble or other obstructive material, the hunt was on ….

The microclimate in the woodland recently has been conducive to fungal growth and this rather intriguing material was spotted on a fallen willow branch.  Immediately recognisable as a species of ‘oyster’ fungi.  No stem was present and the fungi was growing directly from the timber.  Particularly noticeable was that the fan was possessed of hairy-fibrillose growths in its dark centre.  I nick-named it ‘Punk-oyster’ and took the photographs below to aid identification and reference upon return to my library.

Out came the faithful Phillips (1981), Bon (1987) along with various other tomes but nothing akin to the grey ‘Punk-oyster’ we’d photographed.  Trawling the internet can often produce useful indicators but not in this instance.  Drastic measures were needed now so I posted an appeal for assistance into the ‘twittersphere’ and in no time at all the helpful Lukas Large a Natural Science Curator based in Birmingham came back  with a link to a site which certainly tested my language skills but it was an start to determining the material.  Further exploration of the web established that it had been found in the Sorby NHS area in the Limb Valley in 2010, so whilst not a new VC63 a possible new record for Thorne Moors?

Keen to get confirmation of the tentative identification I emailed the images to Chris Yeates the Mycological and Lichenological Section Recorder of the YNU.  The prompt response confirmed the determination and provided some useful additional background information on the species including the distribution map for Yorkshire.

This was great news and pleasing that the images were deemed of good enough quality to allow determination.  It is not always possible to make identifications from photographs and in the case of fungi, spores are often needed for microscopical examination.  Chris added that Apparently some authorities consider this as a form of R. applicatus; I’m not sure whether the necessary sequencing has been done but macroscopically they seem perfectly distinct.

Chris also remarked that the map below was prompted by this record. Whether this somewhat compact pattern is real or not of course is difficult to say, although this species has few records north of Yorkshire (those do include single records from Orkney and Shetland!). Your record is indeed the first from the Thorne area as far as I am aware.

So, is this a new record for Thorne Moors?  Let me know if you believe differently.

Badgering away ….

February 23, 2014

The weather was pleasant, the kind of weather you feel like rambling around the moors.  But, a gathering was calling …. what is the collective noun for a group of naturalists?  In the interim of discovering the noun, a distinguished collection had gathered for Sorby Natural History Society’s fifth South Yorkshire Natural History Day.  We set up the Forum’s display – I have to say the new roller banners look great but the invertebrate exhibits that Peter and Paul brought along go a long way to evidencing what science the Forum has been undertaking.

There was a crammed programme of talks, all the kind that leave you feeling that there aren’t enough hours in the day to do what you’d really like to do.  Garden acculeate hymenoptera, which illustrated opportunities which might exist on your doorstep.  Odonata target species towards the atlas in prepThe state of scientific collecting in Yorkshire was an interesting presentation following analysis of a survey undertaken amongst Sorby NHS members.  Somehow it fell flat for me and that was in no way down to the speaker who was quite rightly a justified enthusiast for the practice of collections and voucher material accompanied by accurate data.  Is it a sign of age when experience acknowledges that the area where you live (or rather pay Council Tax to) has no real interest or enthusiasm for its Museum service?  Doncaster Museum for example houses some significant collections including George Hyde’s substantive series of Large Heath Butterflies.

The real passion verging on understandable anger came from the South Yorkshire Badger Group’s speaker who provided an update on the ‘badger debacle’.  You only have to look back over the last four decades or so to realise what started out as a disease of cattle has now been media managed by the agri-industry to become a badger problem.

It seems astonishing that it is the country’s badger groups who are funding vaccination programmes in hot spot areas.  Owen Paterson prefers a cull despite the fact that the Kreb’s trial tested some 11,000 badgers and found that only 166 animals were infected.  I reckon my calculator must be dodgy because it makes that 1.5% of a pretty significant sample!  What more recent independent science had been commissioned?  David Miliband commissioned the following: Bovine TB: The Scientific Evidence A Science Base for a Sustainable Policy to Control TB in Cattle An Epidemiological Investigation into Bovine Tuberculosis Final Report of the Independent Scientific Group on Cattle TB Presented to the Secretary of State for Environment, Food and Rural Affairs The Rt Hon David Miliband MP, June 2007

An interesting quote by Professor John Bourne (Chair of Independent Scientific Group (ISG) on bovine TB) who said “I think the most interesting observation was made to me by a senior politician who said ‘fine John, we accept your science, but we have to offer the farmers a carrot.  And the only possible carrot we can give them is culling badgers’. 

When you start researching the various arguments it is absolutely astonishing to discover the facts and the fiction.  How many readers are aware of which way their MPs voted, for or against the cull?  When did the incidence begin to reach the plague proportions we hear reported in the media, why did poor ‘Brock’ become the scapegoat?  I can offer no better background reading than ‘Badgerlands’ a well researched book by Patrick Barkham (also author of The Butterfly Isles).  The book takes the reader through the centuries and mans relationship with the badger.  Barkham explores and appreciates the complexities faced by farmers whose livelihoods are impacted by the disease but equally he delves into the politics of the problem and here you sense frustration.  Barkham’s style is enthusiastic and infectious at times and if it achieves readers actively engaging in the debate then that is an added bonus.

Brian May championed the call to the Coalition Government to rethink the cull, that petition is now closed having reached a staggeering 300,000+ signatures which requires a response from the Backbench Business Committee (BBC).  Mmmh, call me a sceptic (although I’d prefer realist) but I shan’t be holding my breath for anything positively proactive or pragmatic from many of the incumbents in the Westminster penthouse.  But at least that action sparked a chain reaction which has seen groups work collaboratively and that is people power promoting change, let’s have ‘moor’?  Team Badger for example is an interesting mix who champion the case for that crepuscular and enigmatic black and white icon of the British countryside.  It supports vaccination as an alternative to culling.  According to the tbfreeengland website 213,799 cattle have been slaughtered since 1 January 2008, from 8 million animals tested, that represents 2.67% of the test sample which was a considerably larger sample than that of the Kreb’s trial.

If the Wildlife Trusts and Badger Groups are funding vaccinations in hotspots why haven’t the NFU assisted?  Damien Carrington’s Environment Blog reports on an interesting NFU approach to opposition.

Katy Brown writes for Ethical Consumer magazine and asks “Why are the supermarkets keeping so schtum about the badger cull?”

Surely, it is not beyond the wit of man if there is a will there is a way forward?  We can fly a man to the moon, why have successive Governments failed to find a scientific solution to this disease?  But, whilst this is not a new problem clearly it does need a new approach.  Dump the polarised views, the black and white exremes and collectively collaborate?  Now that really would be something?   If we subscribe to the view that we all share this planet and it is on loan from future generations, the we need to leave it rich in wildlife not depleat ….

Rethink the badger cull is an epetition still running by 38 degrees.  See also Petition against badger cull.  Another HM Government epetition, initiated by Nigel Ross is still running here.  It runs until 09/09/2014 and currently stands at 7,618 signatures.  It needs a bit of help to reach the required 10,000 to ensure that the Government’s BBC discuss it!
