Knole Park, Nov 2015

Knole Park is full of deer; Fallows and Sika.  These three were by the side of a pond, a lovely spot that is not so easy to find unless you know it's there, because the pond is off the main path, is quite high up and is not overlooked.

I was confused by these because of their winter colouring, but luckily the experts on the iSpot site knew what was what.

It was a drizzly and overcast day.

I have shown this pond before - here is the same pond last year, on a much sunnier day.

I was hoping to find lots of waxcap fungi, as we did last year, but I only spotted two species.  But I did see a tree covered with fruting bodies of the Hoof Fungus, sometimes called Tinder Fungus, known to have been used as tinder 5,000 years ago.

I think this tree must be well known to fungus fans.  It's clearly visible from one of the main paths, and one fruiting body has been sawn off, presumably taken for study.  The one at the top left of this photo is also missing a chunk.

Somewhat less obvious was this small but pretty yellow fungus in the short grass.

The books say this Meadow Coral is common, but I do not actually see it very often.  The same is true of many other species!

I also checked out the western wall of the enclosed gardens, where two years ago there was a good display of ferns, polypodies and at least one Black Spleenwort.  But a year ago they looked unhealthy, and now they have all dried up and disappeared.  Shame!

Petts Wood

Willett Memorial Sundial, Petts Wood.  October 2015.
Willett Memorial Sundial, Petts Wood.  October 2015.
Petts Wood is on the borderland between London and the countryside, where suburbia alternates with fields and woods.  Parts of the countryside in this sort of area are only there because they have been saved from development, and this is the case with Petts Wood and the Hawkwood Estate.  Petts Wood is also the name of a suburb just over a railway line.

There are two memorials in Petts Wood the wood.  One is this memorial sundial, which I wrote about four years ago.  Since then, Google Translate has improved.  The Latin inscription ""HORAS NON NUMERO NISI AESTIVAS" now comes out as "Summer hours are not numerically," which almost sounds like part of a real sentence.  There is a leaflet which gives it as "I only tell the summer hours," which is even closer.  Literally, it's more like "I don't tell the time unless it is summer."   It ought to add "And the sun is out," which it wasn't when I took this photo.

This is the other memorial, the Edlmann Memorial, commemorating the saving and donation of the woodland.  

The woods are full of pathways, mostly through trees and small screams.  There are a few patches of heath.

They are at  a lower level than the surrounding woods because the topsoil and leaf litter has been scraped away to expose the natural gravelly underlayer.

This is the wood where we found many interesting fungi in October .. there are still some more fungus photos to come.

Mice and Voles

Wood Mouse, Apodemus sylvaticus.  Jubilee Country Park, 15 November 2015.
In mid-November, the Friends of Jubilee Country Park had a "small mammals" morning.  I wrote about one of these small mammal events back in February 2011.  This time, local expert Marcus Jordan and his assistant Steven Lofting did all the hard work.

Marcus Jordan and Steven Lofting.

Here, they are getting ready to work their way around the traps that had been set the previous evening.  The box is to carry the emptied traps, and the big plastic bag is to empty the traps into.

When the traps are set, they contain some straw, some apple and carrot, some seeds and a few blowfly maggots, to cater for any of the variety of small animals that might be caught.  The maggots are in case of shrews, which need to eat very often or they will starve.  Shrews have a very fast metabolism and react badly to being handled, so they are let go straight away if they are found in a trap.

The whole contents of the trap are emptied into the big plastic bag.  This lets the trappers see and sort out what is in there.  In theory it is easy, but in practice the mice and voles are not keen on being sorted out, and this time two of them managed to be up a trapper's arm and away into the wood before they could be grasped.  They are very quick!

The idea is to corner them so that they can be lifted out by their scruffs, rather like kittens.

The creatures are then identified, sexed and weighed.  To weigh them, they are put into a small plastic bag, and the weight of the bag is subtracted from the figure shown on the scales.  The mouse at the top of this page has just been weighed. Then they are released, having suffered only indignity.

Bank Vole, Myodes glareolus.   Jubilee Country Park, 15 November 2015.
We found Wood Mice and this Bank Vole.  The tail is shorter than that of a Wood Mouse, though I didn't manage to capture the tip of it to demonstrate; and it has much smaller ears.  The vole has just been weighed, and unfortunately for it, the weighing bag by that time contained rather a lot of Wood Mouse urine.  They do tend to wee when alarmed.

Marcus and Steven thought at one point that we might have a Yellow-necked Mouse ..


But although it showed some yellow in the neck area, it was not a complete collar, so this was just a big healthy Wood Mouse.  A male, this time.

(All photos taken with my EOS 5DS and 100mm macro lens, not using the flash so as not to alarm or blind the small mammals.)

Later addition: A mammals expert says it is not so easy to discount the possibility that this mouse might be a Yellow-neck, after all,  so it might be better to consider it an undetermined Apodemus species.

What Does a Fungus Look Like?

Daldinia concentrica, King Alfred's Cakes.  Petts Wood, 24 October 2015.

So, what does a fungus look like?  There is no simple answer.  I will start with some from Petts Wood, where the Orpington Field Club's fungus lovers had an outing this autumn.  These are not rare fungi.  You only have to look around, in the right places and at the right times.  It helps if you are with a group, because more pairs of eyes means more things are spotted, and it helps if you, or someone in the group, is familiar with fungi.

This first example, King Alfred's Cakes, grows almost exclusively on dead ash, and pops up along the whole length of fallen trunks and branches.  When young, the outside is this mid-brown colour.  Later, they turn black, like a cake that has been allowed to burn in the oven.  If you cut into them, they have a crisp texture and show this unusual concentric pattern.

This one, Purple Jellydisc, prefers the cut faces of dead stumps.  It could be one of two species, impossible to tell apart without a microscope.

Lemon Disco is smaller, but usually easy to see on old dead wood because of its bright colour.

And the Earth Fan grows on the ground.  This one was on the edge of a small patch of heath, where the soil was relatively clear of other growth.  The green shoots are heather, and you can see the dries remains of bracken, indicators of an acidic soil.

I'll show some more conventional fungus shapes later.

More Fallen Leaves

Rowan leaf-fall.  Hayes, 4 November 2015.
Here are a few more leaf-falls under particular types of  tree, following from the woodland photos a couple of posts back.  These were taken on a walk around my block.

The first is rowan, sometimes called mountain ash.  A small tree with clusters of white flowers followed by bright orange-red berries in the autumn, and a colourful leaf-fall.  This one is in a patch of grass opposite my house.

These leaves belong to a lime tree; the linden, not the citrus tree.  This tree has fragrant flowers that can be made into a refreshing tea.

Horse-chestnut leaf-fall.  Hayes, 4 November 2015.
Horse-chestnut leaf-fall.  Hayes, 4 November 2015.
This horse-chestnut has not suffered too badly from the leaf-miner moth this year.  There are plenty of signs that the leaves have been attacked, but in some years the leaves are almost completely demolished by the end of Summer.

Sycamore leaf-fall.  Hayes, 4 November 2015.

And this sycamore only has a few leaves infected with the tar spot fungus.  Sycamore leaf-fall produces lots of yellows, but lacks the oranges and reds of the otherwise very similar Norway Maple.

All these trees, and several others too, have been used to line my local streets.  It's good to see a wide variety of species.

This is an update to the post I made recently about the Streptocarpus species I grew from seed.  The one-leaved plant has now put out a little cluster of flowers.

Stapelia Seedpod

Stapelia variegata is a South African plant that I have been growing on and off as a houseplant for decades.  It lives outside in a sunny spot all summer, then comes indoors to avoid frosts.

Last year it flowered.

The flower smells of rotting meat and is pollinated by carrion flies, so however pretty it may be, that's a good reason to grow it outdoors.

The, this year, it developed a seed pod.  The pod just sat there until the end of October, when it suddenly opened wide over the course of a day.  That's a full 14 months between flowering and spreading its seed, which seems unusually long to me.

This is the pod just splitting open:

(There is a bit of another plant in there on the left.)  And here's a closer look at the seeds with their pappus.

With those thin seeds, these little packages are light enough to fly in the slightest draught, and they would be all over my bedroom by now if they were not emerging straight into a spider's web, which you can see some strands of at the top of the first photo.

This plant has recently been moved to another genus, and you may see it called Orbea variegata.
