Wildlife in the garden

 Apart from the rabbit, which I am hoping I will manage to transfer out of the garden so I can plant out  my plants safely without them being its dinner, I  love seeing wildlife in the garden. I have managed to take a few videos which I will share.  First of all, a red squirrel:

 Whilst  I was gardening, the blackbird was having a forage in the compost heap:

Those of you who have read earlier posts will know that I do a regular hunt around the garden to remove New Zealand flatworms (which eat native earthworms). They rest during the day under anywhere dark and damp.  I disturbed a whole nest of field mice and was not quick enough to video them all, but one seemed unaware of the dangers of sitting out in the open and was undisturbed by my taking out my phone to video him/her having a wash! This is quite a long video but it seems a shame to shorten it. There's a photo if you don't want to use data to watch the video.

STOPPRESS! Frog spawn has appeared in the pond.

More happenings in the garden

 It seems as though Spring is trying to appear as there are bulbs starting to flower in the garden.

Crocuses, irises and snowdrops

However, not all the bulbs have succeeded in flowering this year as some have been cut off or dug up in their prime.

Remains of the crocuses

Something has dug them up.  I am a bit puzzled as to the culprit as they have not eaten the flowering shoots and I can still see most of the bulbs.  The suspects are:  a rabbit, a pheasant or a squirrel, all of which have been in the garden. I have put some of the discarded shoots in water to see if they will flower, but I am not very hopeful. Time to set up the trail camera to see if I can catch them in the act!

In my last post, I mentioned a small yellow lichen that I had found on a garden branch.  I was not sure what it was and have had (Zoom) discussions with more knowledgeable lichen people. One reason I had confused myself was that there were actually two different yellow lichens, both tiny.

The first one was  just a tiny bunch of yellow lobes with even tinier bumps on the edges. There are two examples in the photo, and the lead from a propelling pencil is an easy way to give an idea of the scale.

The pencil lead is 0.5mm wide

The brown discs with white rims at the bottom of the picture is a different lichen, probably Lecanora hybocarpa. The discs are apothecia (fruiting bodies that produce spores), whereas the yellow lichen did not have any.  A help when trying to name yellow lichens is to put a drop of potassium hydroxide (KOH) on them and see if you get a colour change.

This red reaction rules out a whole group of yellow lichens in the Candelaria family.  It looked as though this little one was a Xanthoria and eventually it was named as either Xanthoria candelaria or Xanthoria ucrainica.  I won't go into the details here but the two species are hard to distinguish from each other.  Even more confusingly, they have now been renamed as Polycauliona instead of Xanthoria!

The second similar lichen  was on the same branch but these ones had apothecia, and turned out to be Xanthoria (now Polycauliona) polycarpa.

 I rather went to town with some microscope investigations. I cut a very thin section of an apothecium to get some spores. The spores are dumbbell shaped inside and have the tongue twisting description of polarilocular.

I have more pictures but I expect that is enough detail for most of you!

A scarcity of lichens

 Whilst staying with family west of London, the house was opposite Sunbury Park, a green space with ancient trees as it once belonged to an courtier who was gifted it by Elizabeth I. To my surprise (and disappointment) the tree trunks were bare of lichen apart from a new one for me, Flavoparmelia caperata.  This is a very common lichen in the UK apart from the North of Scotland.

You can also see some tiny specks of yellow lichen, which is probably Xanthoria parietina, more of which later.  The lack of lichens is linked to the air quality  and pollution as we were in a highly populated area with plenty of traffic.  Some lichens manage to thrive in the extra nitrogen  and Xanthoria is one of them. There are more lichens in the park, as there is a booklet available:

I bought a copy at an excellent café and embroidery gallery in the Park. Two more of my pastimes catered for - eating and crafts! Most of the booklet was about fungi, though there were 10 or so lichens mentioned.  A poor count when I can find more than that in my garden. 

I also did the New Year Plant Hunt and managed to find 11 species flowering.  One was a species I had not seen before, Gallant or Shaggy Soldier. These are actually 2 different species Galinsoga parviflora (Gallant Soldier)  and Shaggy Soldier (Galinsoga quadriradiata)  and I think my specimen was Gallant Soldier as it did not have the glandular hairs of Shaggy Soldier, but  I could not be sure as it is a  plant I am not familiar with. The plant was introduced at Kew in 1796, having come from Peru. It seems that the name Gallant Soldier is a corruption of the Latin "Galinsoga".  You can find lots more about this plant in a blog post at Botany in Scotland here.

The other "foreign" plant I saw was in the park, and there were just leaves, no flowers. But very striking leaves.

With the help of a plant app, it turned out to be Italian Arum or Italian Lords and Ladies (Arum italicum).

Once I got home, I decided to tackle some of the Bird Cherry tree prunings that had been lurking on the picnic table, as I did not want to throw them away until I had looked at the lichens growing on them. So much joy in looking closely at ordinary things!

You can see a few brown scars where I have already taken off some of the lichens to look at under the microscope. Most of the lichens were familiar to me. There were some Lecanoras, most of which have  a white background and "jam tart" fruits:

This one was Lecanora carpinea (now renamed Glaucomaria carpinea) which has a white frosty look (it's called pruina) and the discs turn egg yolk yellow when a drop of bleach is added (C+yellow).

Another really common one is Lecanora hybocarpa. To ID it you have to take a slice and put it under a microscope with polarising filters to see the crystals glowing.

The section shows small crystals along the top which "snow" downwards, and bigger crystals lower down in the green area.

Some  of the lichens were easier to ID just by looking, with no special tests needed. This warty one has big apothecia. It's Melanohalea exasperata.

A rather wet lichen

There was one tiny yellow lichen that I had not noticed before.  Here it is next to Xanthoria parietina. 

The bigger yellow lichen at the top is the  X. parietina but I was interested in the  small one on the bottom twig which is only a few millimetres across. I have spent several days investigating it and I think I know what it is now, but I will check in with some of my lichen friends on Zoom to confirm it.  I'll share the details in another post!
