Mushroom season is definitely here.

Such a strange colour: surely Chlorociboria. You can read about it on Tom Volk's pages.  It stains the wood green - this was used for designs in 17th century inlaid boxes (Tunbridge Ware).

I went for a nice walk with my sister in Lower Woods this weekend. It's a lovely ancient woodland owned by the Gloucestershire Wildlife Trust. You'll probably get a trip out there on your course at some point. We were idiotically intending to go to Westonbirt (the national tree zoo nearby) but I freaked out at the vast numbers of people flocking towards it (very slowly, the jams went back miles). It was like trying to get into some massive festival. No-one much was at Lower Woods though. I felt calm again.

I don't know what these lovely peachy furry brackets are yet.

I thought you might like to see a few of the things we saw. We stuck to the paths and were only looking at Things On Logs so I imagine there'd be many more traditionally mushroom-shaped species about. But we mostly saw the freaky things on decaying wood.

Maybe Ascocoryne sarcoides. (Some convincing likenesses at First Nature.)

So if you find anything interesting, please do bring it in to be frozen, and I will pop it in the queue for the freeze drier. I've already done some mushrooms for several students and it seems to be working well.

Dave found some Hedgehog fungi on a walk at the weekend. Imagine the excitement. They have spines instead of gills. Whatever next.

And speaking of strange things,  I also found this, which turns out to be not a fungus at all, but a slime mould, namely Lycogala epidendrum. It was squishy to the touch. I do have a habit of investigating the relatively squishiness of all the peculiar mushroomy things I find. It's helpful with identification (and if you get unsuspecting accompanying friends to try too, you get a range of squealing noises).

These are very strange things. There are some more species on the First Nature website. Apparently some can solve mazes. I'm not kidding. Read more at the UBC Botanical Garden.

I'm supposed to be packing the field trip. But all this is a rabbit hole of interesting and distracting weirdness.

A quick fungi link: you can read all about Kew Gardens' "Fungarium" here.

30.10 Another mushroom update: I can't help myself so have bought a new book. It's by Peter Marren.  Its beautifully designed cover didn't help stop the money flying out of my account. It's supposed to be very engagingly written, and I hope it will fill me with interesting information to trot out to fellow mushroom hunters on field trips. I also read a very interesting article by him on A New Nature Blog in which he refutes the Forestry Commission's idea that picking fungi is Bad (for the fungi, that is).

You too may well find something interesting

Student B's exotic arachnid friend

This time last year I reported on an ex-taxonomic collectioner who had found a very rare and lovely lichen. You see, how many people are actually looking for these things? Not many. Most are watching ITV2 and playing games on their phones. And even the ones who are interested, are generally happy enough to leave their identification at "lichen" or maybe "some sort of Usnea lichen". But (unless it's really difficult to tell and drives you mad) there's much satisfaction to be had from being able to pin down the exact species.

This week, Student B brought in a cute little jumping spider (family Salticidae) which he'd found living somewhere at the zoo. There are 38 species in this country. But it wasn't any of those - it had very distinctive white pedipalps (which it was waving about) and lovely little spots on its abdomen. Not really knowing where to begin as there are a lot of jumping spiders in the world, we both asked on internet forums (I don't think this counts as cheating in this case). And it seems to be Hasarius adansoni, a common-enough creature in warmer parts of the world like Australia and Japan.

Come and use the lovely microscope camera with your finds- drop me an email.

I looked it up on the Spider and Harvestman Recording Scheme website, and they only have 3 records of it in this country (ever), so I am urging Student B to send in his sighting. Maybe it's living everywhere and nobody's noticed - but maybe it's not. Certainly nobody else has ever reported it from Bristol Zoo. So be encouraged - you really can add to the knowledge we have about the species in this country. You don't have to find anything so exotic of course - even reporting common species is important to provide data about how their numbers and distribution might be changing, or the times of the year that they're active. It's all useful and feeds into a bigger picture.


Meanwhile - I had word from an ex collector of bryophytes, Student H. She's currently on a Bog Conservation placement in the Pennines. She's become so enamoured with the mosses there, that she's set up her own Instagram moss page. How cool is that. It makes me feel very happy. Fluffy and feathered creatures already have a lot of supporters. You can make a difference for the more weird and wonderful plants and animals of this country.

I feel like I don't know anything (but that's alright)

 This morning I have been decanting some Tullgren funnel samples into pots for another class. I'm never fully convinced by whether they work, and also the leaf litter that was collected for them was pretty crispy - so the pots aren't exactly overflowing with creatures. But even so, I've spotted things in there that are going to make me look ignorant if someone asks me what they are.

Last year I spent a considerable amount of time swotting up about little soil creatures and making a guide: I learnt about things I had no idea existed (Protura, Symphyla) and realised I knew close to nothing about the groups I did recognise (Millipedes, Centipedes). And then today I ruefully realised that there are many many more things I don't know about that might be in those pots (Barkflies, Thrips... who knows) and I'm not going to become an expert before next week's class. Much as I'd like to be, for the students' sake as well as my own.

But this is not a reason to give up, is it. It's a reason to start. The world is full of amazing things. You can go and look for them and dip your toe into understanding how the world works. Knowing what's out there and where it is, underpins any scientific research in ecology and conservation.

I also find it quite good for existential angst, as all those plants and creatures are out there doing their thing regardless. That's quite reassuring when you get depressed by the absurdity of your own species (from international politics, to celebrity 'culture', to daft things happening in your own social sphere, to your own behaviour).

So my point is, don't be daunted by feeling you don't know anything at the start of this assignment. Ok, maybe some people know a little. You might fear they know a lot. But it's not a 'zero sum game' as they say - their knowledge isn't going to make yours less, and in fact I can tell you from experience that people are very generous in sharing their skills. Pick something you think you'll find interesting, and dive in. Rome wasn't built in a day (and all that). Remember that all those admirable experts started with a single beetle, or wild flower, or barkfly, once upon a time. Begin now.

P.S. A ridiculous and authentic post script.
I spent some of the lesson staring down a microscope with student J, trying to work out what the tiny 4-winged, long-antennaed creature in the petri dish was. In retrospect I think it was a bark fly, though this definitely didn't occur to me at the time. It's a shame isn't it. I can only trust that your young flexible brains will cotton on to things much faster. Here's a gallery of them so I don't get confused next time.

Welcome, neophyte taxonomists

  Heaps of people over the years have said to me this was their favourite assignment. I think it's because it gives you the opportunity to develop a genuine 'natural history' type skill - not only the sort of thing that will impress if you go for an ecological job, but also something you can get personal satisfaction from, when you start to recognise (and indeed, start to really See) the plants and animals around you. Maybe an interest in this sort of thing might have been behind you choosing an environmental course in the first place.

I always tell people to Begin Now - but it's really useful to take some time first to think what you might like to collect. If you find this difficult, think about what you might not want to do, and whittle away the options from the other end. Some people might have an existing interest, or a natural preference for animals or plants. (Not all animal-collecting necessitates death, by the way - you could choose snails and other molluscs and just collect empty shells). Some groups necessitate travel (don't choose seaweed if you can't easily get to the sea...) and most do benefit from visiting a range of habitats. But if you can't get far out of Bristol, some options are still very do-able.

Some nice maritime lichen I saw on the Cornwall field trip this year

Specimens of some groups are harder to find than others; some are seasonal (it's already too late really for grasses and Asteraceae). Some are easy enough to collect and preserve, but need more time to identify (like mosses, lichens and spiders). Some need identifying quickly before important features fade (like mushrooms) whereas others can be pored over at leisure (snails). Some need preserving quickly before they cause smells your housemates will complain about (seaweed). Don't waste your efforts - make sure you know the correct preservation technique for your group before you go out collecting!

If you like squinting down a microscope (and I do), then that's essential for some groups but not others. I enjoy the nerdy puzzle-solving of identifying a beetle from a key riddled with long words. I also enjoy looking at the amazing and unexpected detail of lichens, beetles, spiders, mosses (indeed anything) under the microscope.

 Some groups (like beetles) have many many species in this country - and it's literally a lifetime's work to become an expert - but you can start with just a few. Other groups have a limited number of British options and you can soon feel like you're getting to grips with them, though you might find you have to go out of your way to get the less common specimens that will get you a distinguished mark (trees and ferns maybe).

I hope you'll feel motivated to discover more about the species you find, and go out of your way to find more than just the 'minimum required': I hope you enjoy learning something new, and get a good mark too. The 'useful overview' on the left explains the basic elements of the assignment, and you can pick through the list of options under it. The 'cloud' on the right has all my waffling thoughts (among which are helpful hints I hope). But please feel free to contact me - send me an email or drop by to OJ16.

Collecting marine molluscs

Don't forget your notebook. Image by William Strode.

 You've doubtless experience of finding shells on a beach. But bear in mind, that to score top marks, the quality of your specimens is very important. They have to clearly show all the characteristic features for identification (their presence will not only impress the markers, but also stop you tearing your own hair out). Ideally your bivalves should display both parts of their shell - which may have different shaped teeth and other features. Realistically, you might not end up exhibiting the two halves of an individual animal, but that's ok. Gastropods should also not be too worn, and retain their original shape at their tip and aperture (empty shells can get damaged as they roll about among stones on a beach). Patterns of colour can help identification sometimes, so a shell in good condition is important for observing those too.

You can certainly find empty shells that will be in sufficiently good condition, so direct involvement with Death is not necessary for this group. However, if you find you want to take live specimens, and kill and clean them, then that's up to you (and some shell enthusiasts think this is the way to go). People have been boiling and eating shellfish for a very long time, so boiling's probably the method to go for. (I think I must officially recommend against the gastronomic part of the process - it's not always obvious whether 'effluents' are entering the water where filter-feeders live, and you'd need to keep them super-fresh even if not - or horrible gastric effects tend to result).

I've been looking at the website of the Conchological Society of Great Britain and Ireland, and I notice they have some detailed tips about where to seek out molluscs on rocky shores. You can look beyond the more obvious spots in rockpools and on boulders - you'll find other species lurking in crevices, in amongst seaweeds, under rocks, or specialised to live in areas with sediment or places where the receding water moves quickly. But do remember the Seashore Code (as set out by Buglife here) - and replace rocks and weeds if you move them to look underneath.

The 'Conchsoc' also has some good ideas about equipment you might like to take on your expedition. It's a bit of long list, though (as for many other groups) the most important things to take are waterproof label-able boxes or bags, and your notebook. As collecting environments go, you probably need to consider possible dangers more seriously, and take responsibility for your own safety (think about appropriate footwear and clothing, the times and directions of the tides, and which are safe / unsafe places to be collecting). I speak as someone who once broke their hand falling over on a rocky shore. I sat there pathetically in my rock pool until a kind soul hauled me out. Don't let this happen to you.

Hokusai's 'Shell gathering'

You can read my general remarks on collecting - and bear in mind the principles in the Joint Committee for the Conservation of British Invertebrates' code of conduct. Take empty shells where possible, don't take more specimens than you need, and do as little damage to the habitat as you can. Only a few mollusc species are protected under the Wildlife and Countryside Act 1981. They're rare and so you're unlikely to come across them - but it doesn't hurt to be aware of which they are.

Realistically, if you're on a beach where other people are wandering about, it's unlikely anyone's going to challenge you or haul you off to court for picking up a few seashells. But, I feel I ought to offer you some legally inexpert advice on where you can go and what you can do, and why seeking permission is not a bad thing, so I've written a page about that.

 Read on for information about identifying your specimens.

My improved offer for budding coleopterists

I have just been on a weekend course about beetles, at a Field Studies Council centre in Surrey. Yes, such things exist, and it's marvellous that they do. Imagine entering a room with a dozen other beetle fans and not having to explain yourself; being able to make enthusiastic gasping and squeaking noises about the creatures without restraint. It was great. One day I hope you will appreciate this sort of thing even if you don't now. You meet like-minded people who care about the environment and have a passion for a niche aspect of it: I'm very lucky in my job but a lot of people never experience this day-to-day. The enthusiasm of others inspires you to learn more and more. We were taught and guided by a very knowledgeable (yet very modest) expert - county recorder Steve Bolchover. Unlike when you're working alone, you don't have to sit in a limbo of not knowing if you're doing things and identifying things correctly or not. So that expert support helps you accept and absorb information much faster.

Obviously there's only so much you can take in over a weekend. There are a huge number of species in this country and most are not easy to identify for the beginner. In fact the enormity of the task seemed even more daunting at the end of the course than the beginning, ironically. But I now have more tools in my arsenal to draw on.

By Harde and Severa. It's old and it doesn't look 'serious' but it's the only book with so many illustrations.

I have a couple more strategies to share with you for identifying and displaying your specimens. I have bought a new book (I will never, ever have enough books I suspect - Steve had dozens, many obscure and some in other languages), and I have some other useful identification materials kindly shared by the tutor. I have a new appreciation and enthusiasm for card mounting small specimens, so can help you with that, and new advice about collecting techniques and despatching methods.

 It's been very dry and hot as you know, so there weren't a huge number of beetles that could be easily found: most of the ones I found were tiny. They might have been tiny, but they were still really amazing under the microscope - they can have such superb colours and sculpturing of their bodies. I found and managed to identify the beetle above, Crepidodera aurata. 'Aurata' means 'golden'.

I felt quite chuffed to pick up a Lesser stag beetle (Dorcus parallelipipedus) from under some wood (as the picture at the top) - but this was nothing compared to the female (not Lesser) Stag beetle (Lucanus cervus) that my course-mate found on our trip to a common. It was unmistakable and massive - it's this country's largest beetle (you'll be pleased to hear it was allowed to go on its way undisturbed). So that was an excellent moment and proved that you don't know what you're going to find - but you have to get stuck in and grub about to look.

Asteraceae: a good choice for summer collectors

Ox-eye daisy in the University of Neufchatel herbarium.

 Student K came in for a bit of support with her Asteraceae collection yesterday. I brought in my 20th-century collection to show her. As you will find out one day, it is slightly shocking how time flies. However, my pressed plants were still looking ok despite their advanced age. I had 35 species, and do you know what, I got a 2:1 for it (at least, that's my recollection)! Either my university had quite a different mark scheme. Or else it's an example of so-called grade inflation :)

 But don't you worry about that - I reckon you'll get a first if you turn in 35 species. Student K made a good dent on that number yesterday: we had an amble round the scruffy parts of campus and found 19. This is definitely the moment to go collecting Asteraceae. Grasses seem to have faded in all this heat, but the Asteraceae don't seem to care so much. I think my favourite was the slyly spiny Prickly lettuce (Lactuca serriola). It's full of milky latex (a trait you'll know from Dandelions) and has skin-snagging prickles along the back vein of the leaves. Both things would be enough to put off potential nibblers (large and small).

Distinctive weirdness on Perennial sow thistle. CC TeunSpaans.

 My other favourite was Perennial sow thistle (Sonchus arvensis). It looks a bit like a dandelion to the uninitiated, but is much bigger and branchier, has nice leaves that clasp its stem, and most superbly it has weird blob-tipped glandular hairs (get out those hand lenses). I imagine they're to deter little insects.

And remember, that although lots of species like tufty wasteground, if you expand your horizons you will find more species (and impress the markers). K lives near some saltmarsh: I suggested she might find Sea aster (Aster tripolium) there.

 Meanwhile there are other species that specialise on chalk grassland. I recently went to visit Student M on her marvellous placement looking after rare butterflies on a very steep calcareous grassland hill: she's noticed many lovely Asteraceae there including the Dwarf thistle (Cirsium acaule). I think I spotted the beautifully geometric Woolly thistle (Cirsium eriophorum) too.

Mmm so geometric. CC image Derek Harper

The picture at the top of the page shows a beautifully pressed Ox-eye daisy specimen in the University of Neufchatel herbarium - the sort of thing you could definitely emulate with your specimens. I think it's held onto the paper using this technique.

Now I have to go and squint at some mosses and lichens - first to identify them, and then to make something to help the new first years identify them as part of a new activity on Dartmoor. A nice job if it didn't require quite so much concentration in this heat. But do contact me if you'd like any help or advice about your botanical and entomological exploits.
