Guessing at Fungi, and a Sly Visitor!

If you've been reading my blog in the past few months you will know that I love fungi, but it's really a very recent thing that was kickstarted last autumn, when I was looking for birds (unsuccessfully) in a local wood, and suddenly noticed I was surrounded by autumn fungi, of all shapes and sizes. Then it turned into an obsession when I was in a German wood and found fungi in red, yellow, green and purple, and all kinds of shapes and textures. From then on, I've been noticing fungi everywhere.


I can't remember why I never noticed fungi before this autumn, as I was always out birdwatching before that in places where fungi might be found. I think it was something to do with an idea I had about most fungi being brown and white mushrooms that all looked the same and weren't very interesting. I knew there were more different shapes and colours and textures, but I thought you had to be an expert to find those ones, and you'd only get to that point after getting really good at looking at the brown mushrooms. However, I now realise this is absolutely not true- once you begin looking out for fungi you will start to realise that some of the commonest species of fungi are some of the most brightly coloured, strangest in shape, and weirdest in texture! I'm going to go on to show you some examples that I found in the past couple of months at my local patch during my weekly bird-counting visits- despite the bright colours of some of it, I might have overlooked if I hadn't had my eyes open for fungi.


First, a quick note: fungi is awesome to look at, but even species that look really distinctive can be strangely hard to identify. I found this out with my Meadow Coral/Yellow Stagshorn confusion in the Germany post I linked above, and from some correspondence I had with the excellent Mark Baldwin at Wildlife Online (http://www.wildlifeonline.me.uk/) I learned that photographing fungi where it grows may not be enough to always be sure of a positive ID- you may need to photograph the gill structure as well, or cut it in half to look at the structure inside, or for some of the 'brown mushrooms' I mention above, you might even need to taste the fungus's secretion! (Note: do NOT do this unless you are an expert!!! I certainly won't be trying it for a while!) The identification book for fungi that I use (which Mark also recommends), is Mushrooms by Roger Phillips, which I have on long-term loan from my dad, but I really must get my own copy ^^- this book includes how common a fungus is which is really useful (and also how poisonous/good to eat a fungus is, which is just interesting!). To back this up, when I think I've IDed something I use the Hampshire Fungus Recording Group website that I mention at the end of this post, and if there's not many records of it I reconsider the plausibility of my ID. I may also do a google image search on a species I think I've found, especially if it looked close but was a slightly different colour or shape than in the picture in the book, as fungi are widely variable in colour and shape (some with age, some...just to be annoying, I think XD) and an image search should show you several variations of the same species.


Now: on to the fungi!


I think these interesting little things are most likely to be Common Jellyspot, even though most of the pictures I saw of Jellyspot were more orange than these various shades of pink and maroon! I love the huge variety of shapes, sizes and textures that were all on the same log. The incredible smoothness, curvyness and shininess looks like some sort of modern art. Looking back at these photos now, I kind of wish I'd poked them with a stick to see if they were as squashy as they look! In the 4th photo down is what looks like one that's been squashed, so maybe they are.



These are both the same one- you can see in the top one how it seems to melt into the tree, and in the second one how high the dome is. I love this one because of how wet and jelly-like it looks, as if it's sort of melted down over the bark! Unlike the Jellyspot (and most other fungi I seem to see), this one was on its own. This was hard to ID but I think it might be White Milking Bonnet? Heeding Mark's advice about the gill structure, and also because I wanted to see what the stem was like under the cap, I took the following photo:

I had to make it bigger than the others as it's one of my favourite photos I've ever taken! :D

Even though this photo came out really nicely, I'm not experienced enough to actually use the gill structure to verify ID yet. I think the White Milking Bonnet is a subspecies of Milking Bonnet, and there aren't as many records of White Milking Bonnet in Hampshire as there are Milking Bonnet, but it's tricky with subspecies. This was a really hard one to get even a tentative ID on so if anyone knows about Milking Bonnet-type fungi or has another ID suggestion for my melting white mushroom, let me know! :)



This little bright one was a relatively easy; it's a Yellow Brain fungus! I couldn't have thought of a better name myself. Again, these are photos of the same one from different angles.


This one was an odd one. It looks quite like the Jelly Spot without any of the colour, but I found a photo of a fungus that looked like it in the suggested images while looking at google search results for the Yellow Brain- clicking into it showed it was called the Crystal Brain. Despite the name, as you can see it's not really that similar looking to the Yellow Brain, and the Latin names (Tremella mesenterica and Myxarium nucleatum) suggest they are not closely related at all. (Even fungi that do look alike aren't necessarily related, of course!) Crystal was the closest ID I could find for the fungi in the photo, but weirdly Crystal Brain wasn't in Roger Phillips' fungi guide at all, not even under the Latin name. But when I searched the name in the Hampshire fungi site, there were many records. Does anyone know why it might not have been in the book? Very odd, and it's a good thing the name is similar to the Yellow Brain or I might never have even had an idea what it might be!

********************************************************

The more interested I get in fungi, the more I see it everywhere! And to an extent, the same thing is happening with signs of mammals. As I wrote about in this post, I've been keeping notes about signs of mammals I see for the National Mammal Database, and my local patch is no exception. Warning in case you're eating dinner: poo pictures to follow!


Up at the top of my patch there's a railway line surrounded by scrubby vegetation, and back in January I detected a sly visitor up there! Unlike most mammals, you can sometimes detect this one with your sense of smell. Walking along the field margin next to the railway line, I smelled a distinctive, spicy, peppery odour that can only mean one animal- a fox! And aside from the smell, there were various visual signs.



 My local patch is very popular with dog walkers, and unfortunately a large number of them don't clean up their dog mess, so dog would be the main confusion species for these droppings. However as you can see from the closeup, there are feathers and what looks like crunched up bones in this dropping, not something you'd generally find in the poo of a dog fed on dog food. Plus when I was taking this photo, I noticed that the smell was...actually not as bad as you'd expect from a dog! While dog poo really stinks (and it makes my patch a bit unpleasant on a hot summers day, I can tell you!) this poo merely smelled like more of the fox smell, which wasn't unbearably unpleasant. I haven't included badger as a confusion species for this despite the size being similar, because I've seen no evidence of badgers at my patch or in the area at all, and don't think it's likely. But as I mentioned in the post I linked at the start of this section, badger poo doesn't really seem to have a smell.


I also found these nearby: 



Considering that the fox droppings had feathers in them, and these Woodpigeon feathers have been broken off by the shaft, I suspect that someone caught a pigeon and ate at least some of it near here! A sign you can use to tell if a mammal removed the feathers from a kill rather than a bird of prey is if the feathers are bedraggled, which can be due to the saliva of the animal and the fact that they sometimes chew the feathers. However in this case I think they're bedraggled because of the rain. The feathers in fox poo show a much more likely connection.


And finally, I found what looked like trails a fox-sized animal would make while pushing through the undergrowth: 


I was glad to find so many signs of my sly visitor! I don't know if any foxes have a territory nearby, and I've never seen or heard one in the area near my patch (it's near the suburban neighbourhood where I live, and I've never had any reason to believe there are urban foxes about), so it's possible this fox was just passing through. I did smell the foxy odour on a couple more visits since this, but never found so many clear signs again. This was all found a few months ago, I wonder where the fox is now?

It's funny- the more I look for different types of nature, the more I realise the value of educated guessing. You may not know 100% what you're looking at all the time, but you can get better at guessing, while waiting until you know more, or perhaps meet someone who knows more who can help you. For example, when I first was contacted by Mark Baldwin at Wildlife Online (linked at the top of this post) he verified some speculation I'd been mulling over in my Badger Mysteries post about whether badgers ever kill pheasants and other gamebirds. Mark showed me research that says- they do! It was brilliant to find out for sure. :) Thanks Mark, and as I always say, if you can give me the answers to any of my questions or you want to correct me on something, then I would absolutely love to hear from you!


And as the Spring rolls in, while you're keeping your eyes on the trees and your ears open for birdsong, don't forget to look down to the ground and keep your nose open too! ;)

Recording signs of mammals for the National Mammal Atlas

Note: This post contains photos of dead animals and poo. Just a heads up in case you're eating your dinner!

At the start of this month I was in Wales, and when I came back I was determined to write about the wildlife...but I have epic writer's block on that post. So to try and shift it, here's a post about looking for mammals!

Recently I became aware of the National Mammal Atlas, a project by the Mammal Society to try and map the distribution of every British mammal species, and being someone who loves recording records online (I already submit to Birdtrack, BTO's garden bird count, goingbirding.co.uk, and seasonal counts such as the Big Garden Birdwatch and the Big Butterfly Count) I was very interested in the project. They want every single record, from rare species to common ones like Rabbit, Brown Rat and Grey Squirrel. As well as reports of living mammals they accept reports of dead animals, meaning roadkill can be a useful record, and they want records of signs of mammals, such as burrows, droppings, footprints or mole hills. As a birdwatcher I sometimes see mammals, but if I'm lucky I might see two species in one trip. So I decided to go on a walk and see how many signs of animals I could find.

Since the weather has been gorgeous recently I decided to go to a good place for butterflies, Stockbridge Down, and sure enough the place was alive with them: Meadow Brown, Gatekeeper, the lovely Marbled White, the tiny Small Heath and the cute, bright orange Small Skipper. Best of all was the large, lurid orange fast-flying Dark Green Fritillary. The Down is also fantastic for birds, and though it's getting to a quiet time of year for songbirds there was still plenty to see, including a male Blackcap popping in and out a tree with beakfuls of food, a blindingly yellow male Yellowhammer singing from the top of a bush, and a flock of 5 or 6 Mistle Thrushes (maybe a family?) flying by.

But what about the mammals? By the time I arrived at the Down I unfortunately already had records for two species from the drive over. I say unfortunately because of course they were roadkill: a Grey Squirrel about halfway through the journey, and rather heartbreakingly, a Badger, very close to the entrance to the Down. I've never seen a living Badger before (though I have found signs of them) and I hate seeing them dead on the roads. Then I had barely stepped through the gate of the nature reserve before I found a third mammal, a Common Shrew. This is another animal I've never seen alive, despite it being incredibly common in Britain; I expect it's probably nocturnal like a lot of small rodents. This, of course, is why records of dead animals are useful to the Mammal Society- otherwise they'd end up with far more comprehensive records for diurnal animals than nocturnal animals. Anyway, here's a picture of the Shrew.


Poor little thing. Ask anyone: I have a soft spot for small furry creatures. ^^ You can tell this is a shrew by its very pointy nose (unlike the rounded nose of a vole) and its hairy tail (unlike the bald tail of a mouse) that is short compared with the body. Finally, the teeth of a shrew are tipped with red, as you can see in this close-up:


I would love to find out why the teeth are red, so if anyone knows, let me know. 

As for how I know this is a Common Shrew and not one of the other kinds, I confess it was mostly process of elimination: the Common Shrew is far more numerous and therefore it is most likely to be one. The fur colour (warm brown rather than dark grey) and size (about the size of a mouse rather than smaller) also helped me come to this conclusion. 

How it died is a bit of a mystery to me, as being killed by a predator would seem the most likely cause of death, but why would the predator then leave its kill? But then on the Mammal Society information page on Common Shrews, I found this: 'They are often found abandoned by the predator..since a liquid produced from glands on the skin is foul tasting.' So that seemed plausible. And in the first photo you can see what looks like it might be the fatal wound, on the back of the Shrew's neck, which is where a predator would bite to kill its prey.

As I continued my walk, I found mole hills, and burrows covered with rabbit droppings, as well as the only living mammal I saw on my walk: a lone, alert-looking rabbit! Rabbit droppings are easy to identify, but later on I found some poo that caused a bit more confusion.

 


As you can hopefully see in the close-up, these droppings are packed with beetle shells, which made me think 'Badger!' straight away. The reason for that is I remember when I was a Wildlife Explore (young RSPB member) we found some poo like that on a field trip, and the leaders said it was Badger poo. I did a little research all the same, and then began to be unsure, because I found out that Badgers make latrines near their setts and that's where most of their dung will go. This was found out on the grass, not in a latrine and nowhere near a sett, so I started to look for suggestions for alternative possibilities online. It seems that beetle shells can be found in Hedgehog dung, but to rule that one out size is the main factor, and though I didn't measure the droppings (must bring a ruler next time!) compared with the size of a Hedgehog, I think they were far too big. Domestic dog can be ruled out immediately because the poo didn't smell, and dogs don't tend to eat loads of beetles. Same with sheep, which do graze on part of the Down, but they certainly don't eat beetles. Fox poo can also be ruled out because that has a peppery, pungent smell (I've had the dubious pleasure of finding Fox poo before) which this didn't have at all.

So for a while I was unsure about what I had found here, until I noticed something else which you should be able to see in the close-up: there's some long, white hairs stuck to the droppings! I'm almost sure they are Badger hairs, and I already know Badgers are in the area (thanks to my sad find near the entrance of the reserve earlier) so I've reported this to the Mammal Atlas as a field sign of Badgers. Just in case, though, I've attached a photo so the record can be checked. I did the same for the Common Shrew, though not for the mole hills or dead squirrel, those are pretty easy even for a mammal novice such as myself. ^^

The best thing about trying this experiment out was realising how much I might normally miss: if I wasn't thinking about looking for mammals, I might not even have noticed the shrew or the Badger droppings, or the mole hills, which even though they are a common sight, are a sure sign that an animal barely anyone ever sees is present in the area! So, although I only saw that one Rabbit, I also found Badger, Mole and Common Shrew, as well as that squirrel on the journey, and therefore had 5 species to submit to the Atlas. And I learned some new things about Common Shrew and Badgers!

To anyone who wants to submit your own results, follow this link: http://www.mammal.org.uk/ and go to 'submit records' on the left. You can submit any mammals you have seen in Britain since 2000, as long as you know the date and the location you saw it, which you pinpoint on a map. When doing this, it helped me to remember whereabouts the animal was found in relation to a landmark: for example, the dead squirrel was on the road near the entrance to Sparsholt College, so that made it easier to find on the map. At some point I want to go back and submit some mammals I've seen in the past.

Hopefully Wales post will be up next! Because I really did see some awesome things there...
