Yarrow, Sneezewort and a rare find

There are some flowers that appear late in the season and let you know that autumn is almost here - Devils-bit Scabious, Harebells and Sneezewort. You are probably more familiar with the first two, both being an attractive shade of blue, whereas Sneezewort could be mistaken for a slightly larger Yarrow. They are both in the same family, Yarrow being Achillea millefolium with feathery leaves as the second half of the name suggests, and Sneezewort being Achillea ptarmica, where the second part of the name comes from the Greek for sneeze.  Sneezewort leaves are completely different being narrow and toothed, and apparently if dried and powdered they cause sneezing. The other difference, apart from the leaf shape, is that the Sneezewort flowers are bigger.

On our trip to Loch Laggan, the small island was covered in Sneezewort, blowing in the wind.

 Whilst I was looking for other flowers, I noticed a plant with spotty leaves and got quite excited thinking I had found a new plant.

The  spotty plant

Looking at it more closely and at some of the other photos I had taken, I realised it was a stunted Sneezewort suffering from some sort of infection.  The  black spots were on the stem as well as the leaves. And when magnified the spots were bumps rather than just the colour of the leaf.

Fortunately I took a sample back home with me.

Why fortunately? Remember the expert on fungi that I mentioned in my last post? Prof Bruce Ing? He took the sample away was able to identify the fungus. It's  Schizothyriana*ptarmicae. What, you have never heard of it? Well, neither had I.  Even more surprisingly, it got ZERO hits on Google.  It was keen to substitute schizophrenia instead. 

 Surely, I thought, there must be something on the internet that mentions it? Doesn't the internet have absolutely everything there somewhere.... Well, I tried searching with Google Scholar (which searches research articles) and there were a few hits for articles from Poland and Germany. It turns out that it is very rare (23 records in UK) so Bruce has taken the sample away for it to go in a collection. Fame at last!

*UPDATE -I was talking to Bruce today and it turned out there was a typo on the list I was sent and it should have been Schizothyrioma (pronounced with a soft ch) which got 407 hits on Google!

A very botanical weekend

The beautiful sunny weather last weekend was ideal for some botany activities I had planned. On the Saturday, I took a group of people from the Inverness Botany group up Glen Banchor to look at lichens.  Our first stop was an old dry stone wall by the first cattle grid.  This has so many different lichens on it that you could consider it as a lichen hunter's heaven - or hell - as it is covered in crustose species that I can't identify! I had picked out some of the easier ones to spot and put them on a help sheet:

 Even then, you have to get close up and personal when trying to see the features.

A hand lens, x10, or a little device that clips on your phone can really help you to see the details.

Here are two favourites (anything with blood in the name seems to be popular!):

Blood spot lichen (Ophioparma ventosa) growing on the stone wall

Bloody Heart Lichen (Mycoblastus sanguinarea) growing on a birch tree

The Bloody Heart Lichen has black fruits (apothecia) on it but when scratched, it is orangey-red underneath.  This is because you are exposing an  orange alga that coexists with the lichen  (Trentopohlia).  Most algae are green.  Lichens have (at least) two components: a fungus and an alga.  The fungus gives the lichen its name and provides a home for the alga. The alga produces food by photosynthesis.

On the Sunday, I joined in a Fungus Foray around Newtonmore with Prof Bruce Ing. I was amazed at how many fungi a discerning eye can spot.  There were over 50 around Loch Imrich! 

The undersides have a variety of gills and pores from which the spores fall. Apparently a fungus has to grow very accurately vertical as otherwise the spores would get stuck on the sides of the tubes etc when the spores are released!

Bruce also provided a different ID for the log pile fungus (post has been updated) as Lintneria trachyspora.

Bruce is an expert on Slime Moulds and Mildews and for the first time ever I was delighted that so many plants in my garden had mildew! Bruce took away lots of sample leaves, as apparently each family of plants has a different species of mildew ... who knew?

And finally, a visit to a friend's garden produced lots of sightings of butterflies, so here is one I have not shown before. A Peacock (Inachis io). The caterpillars feed on nettles, and the adult butterflies overwinter in sheds and outhouses.

Sea Plantains inland

 If you travel between Newtonmore and Kingussie (a distance of about 3 miles) you can either go by car along the A86 or use the bike path which runs alongside it.

At the moment, there is a very obvious brown strip on the road verge made up of many brown spikes. In the photo above it is just visible between the white van and the post. In the photo below, it is the grey brown stripe across the middle  of the photo.

The colour is made up of the fruiting spikes of the Sea Plantain (Plantago maritima). I took a picture from the bottom of the slope so it is not very clear:

I thought I would have better photos already on my computer - and maybe I have - but I can't find them! It normally grows by the sea but a few plants started appearing at the side of the road a few years ago, and now it has completely taken over the verge for almost a mile. When driving the back road from Kingussie to Aviemore, it is easy to spot on the side of the road there as well. It can tolerate salt which explains its success.

Today I was walking near Ralia and there were a few plants there as well but not good subjects for a photo as the recent tar and chipping had covered everything in white dust!

A rather dusty Sea Plantain flower with yellow stamens

You can see that it has yellow stamens which makes it easy to distinguish from the other plantains which have white ones. There is an interesting post on the edibility of Sea Plantains here.

A more colourful event was the visit of a Small Tortoiseshell butterfly to my Buddleia in the garden.
