As I wrote yesterday, with very little fungi to be found our Glamorgan Fungus Group foray on Saturday developed into a more general nature ramble. I’m afraid I wasn’t writing down the names of all the various critters and plants we saw so I can’t identify everything in these photos but I can name some.

The first is a Red-headed cardinal beetle (Pyrochroa serraticornis), a very pretty beetle though this one wouldn’t keep still for me. The centipede was the same and I’m afraid I don’t remember its name, though I was told it’s not particularly common. It tickled! I think the little yellow dots are the eggs of the Green dock beetle (Gastrophysa viridula) as we saw a pair mating nearby. The tiny moths on the buttercup flower are Micropterix calthella. The plant with the pink flower is one I actually remembered from my botany walk on Thursday – a miracle! It’s Common Stork’s-bill (Erodium cicutarium). Then we have two different species of snail cosying up together. Once again, I was told the names but didn’t write them down and have forgotten (must do better next time!). This very pretty plant was a new one for me and it has two common names, so you might know it either as Wall pennywort or Navelwort (scientific name Umbilicus rupestris). Next is another beetle, this time a Poplar leaf beetle (Chrysomela populi). It was a gorgeous wee thing, with metallic green thorax and dark red body, almost like an oversized ladybird. And, last but not least, was this rather angry Blood bee (Sphecodes sp.). It was trying to lay its eggs in the holes of mining bees when it was netted and potted up for a quick close-up look.

My favourite moment of the day, though, was when I turned over this log. I particularly loved the little grouping of millipede, pill-bug and slug but these were only a few of the various creatures to be seen. It was just nice to see such biodiversity co-existing happily together. A lesson for us all, I think.

Saturday dawned fine and mostly sunny, good news for most but not such good news for fungi enthusiasts, who are already bemoaning the recent lack of rain. Still, keen-eyed fungi fans can always find something and our Glamorgan Fungus Group has some of the keenest in ‘Eagle-eyes’ Emma. Though we were just a small group of six and a half, we enjoyed a splendid day searching the woodland areas of Merthyr Mawr National Nature Reserve, and our limited numbers were, in fact, a bonus, as we had amongst us the county recorder for Orthoptera (grasshoppers and related insects) and an experienced botanist, so we were able to enjoy, discuss and identify a broad range of flora and fauna. As expected, our fungi finds were limited but we finished the day with a very respectable total of 21 species and had a great time along the way.

Here are some of our finds: the rust Melampsora populnea on Dog’s mercury; another rust Kuehneola uredinis, on Bramble; Microbotryum silenes-dioicae, a smut that occurs on the anthers of Red campion flowers; another rust Melampsora epita var. epitea on Spindle; fungi enthusiasts inspecting the one group of cap fungi (‘real mushrooms’) found this day; the ‘real mushrooms’ that must remain unidentified as they were much eaten and turning gloopy; likely one of the Mollisia species of Disco fungi; Phellinus hippophaeicola on Sea buckthorn; Phylloporia ribis on Spindle; a rather old and faded Blushing bracket Daedaleopsis confragosa; a Puccinia species of rust on Common ragwort – this needs microscope work to positively ID; and the pimple-like growths of Dandelion wart Synchytrium taraxaci on one of the gazillions of Dandelion species, so Taraxacum officinale agg.

Fungi Friday: The rust challenge

Back in January I posted about the Cobalt crust-finding challenge I was taking part in with my friends from the Glamorgan Fungus Group. This month we’ve been at it again but our challenge species are rusts, specifically Uromyces dactylis (below right) and Uromyces ficaria which are both found on Lesser Celandine; Puccinia urtica (below left) on Nettles; Uromyces muscari (the other four photos) on native, cultivated and hybrid Bluebells; and on Nipplewort Lapsana communis.

Though finding and photographing the Nettle rust is more for the masochist than the faint-hearted – our group has joked about buying thick rubber gloves up to our elbows(!), the other rusts are less dangerous though no less of a challenge. I’ve had most success with the Bluebell rust – probably a reflection of the fact that everyone loves Bluebells so they’ve been planted almost everywhere, but have found only one specimen of one of the rusts on Lesser Celandine, despite the flowers being very plentiful and numerous in my local parks and wild areas. And I have yet to find a specimen of Nipplewort rust – probably because I have yet to positively identify Nipplewort (this is why I’ve taken up a botany menteeship!).

Still, just as we did with Cobalt crust, our group members have thrown themselves into this challenge and, to date, our combined total stands at over 140 separate finds. And, just like last time, our finds are being fed into our local biodiversity database so our challenge is helping to increase the knowledge base for these under-recorded fungi. Citizen science rocks!

My fellow Glamorgan Fungus Group members and I are taking part in another challenge this month, hunting far and wide within the county to see how many specimens we can find of the supposedly rare Cobalt crust fungus (Terana caerulea). You may remember that I blogged about this special, once-seen-never-forgotten fungus back in February. It’s generally classified as rare but, here in Glamorgan, it most certainly isn’t.

Here are the latest stats: for the 14 days from 13 to 26 January inclusive, 14 of our group had made a total of 45 separate finds on 16 different host plants, ranging from elder, bramble and buddleja to hazel, oak, ivy and even Japanese knotweed. Our results just go to show that this fungus is not actually rare but rather rarely recorded, and our participation in challenges like these also highlights the benefits of ordinary folk like you and I making the effort to record the biodiversity we see around us every day. We’re helping to rewrite science!

Fungi Friday: The Holly parachute challenge

My friends and I from the Glamorgan Fungus Group have a team challenge going on and, if you live in Britain and enjoy fungi forays, this is something you might also like to have a go at. The Holly parachute fungus (Marasmius hudsonii) is usually described in fungi guides, if it’s included at all, as being a rare find but we wonder if it is, in fact, just rarely recorded because of its incredibly tiny size – its maximum cap size is 5mm and it’s frequently less than half that measurement.

As the name suggests, this small and very delicate mushroom is shaped a little like a parachute, though it has one interesting feature that makes identification easy – it’s covered in microscopic hairs that are a real challenge to see with the naked eye but are easier if you use a hand lens or a macro lens on a camera.

As its name also suggests, the Holly parachute grows exclusively on holly, specifically on dead and damp holly leaves like those you can find in the leaf litter beneath a holly tree. You might think that would make it easy to find but it’s not. Holly trees are usually evergreen so shed few leaves and they often grow amongst deciduous trees so, at this time of year, the ground is awash with all kinds of leaves that often smother the few holly leaves that have fallen.

However, members of our group have found Holly parachutes in more than 20 locations in our county since we began our challenge a month ago (I’ve found it twice) so we are leaning towards the idea that it is more common that the records might suggest. How about taking up the challenge and seeing if you can find it in your area?

UK Fungus Day 2016

The sun shone and the people came, full of interest and enthusiasm … but where were the fungi? It had been a dry week and, as Parc Slip Nature Reserve sits on top of an old coal spoil tip, the ground doesn’t retain moisture well, so the fungi were nowhere to be found.

Luckily, Glamorgan Fungus Group president Mike Bright is a man of forethought and ingenuity. When he checked the site of the walk yesterday and found it virtually barren, he spent the rest of the day – six whole hours! – scouring other locations for fungi specimens and, thanks to his super-human efforts, today’s walk was a huge success. Mike led us on a wander in the woods and combined that with a ‘show and tell’ of what he’d found the previous day, and everyone was mightily impressed. I reckon he must take the prize for the best organiser for UK Fungus Day 2016, and for finding the biggest parasol mushroom!
