Skye Botany Group

May 8, 2019

We visited the eastern ridge of Sgùrr nan Gillean yesterday whh was a great day but we again failed to find the Kalmia procumbens (Trailing Azalea) recorded there in 1982. I am now wondering if we should have gone higher.

However, we did find Anthostemella alchemillae, a small fungus that grows on dead leaves of Alchemilla alpina (Alpine Lady’s-mantle). This is one of the fungi featured in the Lost and Found Fungi Project.

Last night Seth did a squash and checked the spores. See his blog.

Otherwise, we added a few plant taxa to this tetrad which still hasn’t quite reached a count of 100 – but that is the Cuillin for you.

Earthtongues

May 3, 2019

I have already shared this on the Skye Naturalists’ Network Facebook page, but for those of you who do not see that…..

Something for later in the year from Brian Douglas, Community Fungus Survey Leader for the Lost and Found Fungi project:0001

Brian says: “Skye is particularly good for earthtongues (notably Microglossum and Trichoglossum species). Thanks to past surveys of Skye (and notably a 2011 Kew/SNH survey) Kew has a lot of specimens from Skye with precise grid references, and some are either new species to science, or species which need more taxonomic work to resolve/stabilise the concepts. Unfortunately most of these specimens lack good photographs, and colours when fresh are extremely important characters for these species. So, if you know anyone on Skye who would enjoy the challenge of tracking down and photographing a few important populations later on this year using our 8fig grid references, and collecting a specimen for sequencing, please let me know.  (There’s also a lot more to the earthtongue story if anyone is particularly interested in helping to resolve it!)

You might also be interested in some of the species of the Lost and Found Fungi project (which I coordinate) – there are a handful of interesting species of conservation interest recorded from Skye and the nearby Isle of Canna which we’ve mapped here: http://fungi.myspecies.info/content/north-ebudes-vc104 . More details of the project and these species can be found on our website here: http://fungi.myspecies.info/…/lost-and-found-fungi-project . Smut fungi on sedges such as Carex limosa, C. pulicaris, or indeed smuts on any sedge would be worth keeping an eye out for if anyone happens to have an interest in sedges or wetland plants/biodiversity.

And of course I’m always interested in any plant-associated fungal rarities, if any turn up that I can help ID…”

Anthracoidea kari, the smut on Carex echinata (Star Sedge) is quite widespread on Skye but others seen very rare.

Brae, Raasay

April 14, 2019

I made a shortish visit to the Brae area of Raasay today to update some old plant records i.e. try to re-find some more of the things I recorded before 2000. This was reasonably successful given the time of year, but I also spotted a couple of insects and a fungus worth mentioning.

I have seen four specimens of the Green Parasitic Fly (Gymnocheta viridis) in the past couple of weeks, but today I spotted another tachinid that may be Botria subalpina, a fly first recorded in the British Isles, in NW Scotland, in 1994. There are still only 13 records on NBN, all in the Highlands, one of which was at my home three years ago. If right, and that will have to wait until I see Murdo at the end of the month, this will be a second 10km square on Raasay where it is known.

I also spotted a Violet Oil-Beetle (Meloe violaceus), the second in less than a week seen on Raasay as Jonathan and Sarah found one at the far north end last Tuesday. One has to be careful to distinguish this from Meloe proscarabaeus – a useful guide is here. There are about as many Raasay records as there are Skye records, so may be something to look out for across the water.

The fungus is worth mentioning because now is the time of year to find it:

Kinloch Ravine and Allt nam Criopag

March 24, 2019

Fresh snow on the hills, hail beating at the window at 8 am, yesterday was obviously the perfect day for my first serious botanical expedition of the year. In fact it turned out reasonably pleasant with just a few drops of rain now and then.

The woods of “Kinloch Ravine” to the northeast of Kinloch Farm were surveyed in 1986 but the site spreads over three tetrads in two hectads and records were not kept separate. Also not far away is the Allt nam Criopag which turns out to have a very impressive and long gorge which, apart from the lower end, can only be accessed at rather few points.

Most plants recorded from the woods were re-found yesterday and assigned to 1 km squares. A few remain that would have been nice to sort out but which were unlikely this early in the year such as Carex pallescens (Pale Sedge), Melampyrum pratense (Common Cow-wheat) and Trollius europaeus (Globeflower).  However, there was a very pleasing colony of Orthilia secunda (Serrated Wintergreen), a new hectad record and only the second site in the south of Skye. It is about 5m up a vertical cliff above the river:

With a little zoom one can see the one-sided infructescence with straight exserted styles and on one image with the eye of faith, serrated leaf margins. The only other possibility is Pyrola media (Intermediate Wintergreen) but as well as the one-sidedness and probable serrations, the general growth form is typical of Orthilia.  (I wish I had had my other camera with me; it is better at the telephoto effect.)

On to Allt nam Criopag where seven 1968 records from John Birks demanded a search, even though it is March. A small patch of Alchemilla alpina (Alpine Lady’s-mantle) was located whilst Arctostaphylos uva-ursi (Bearberry), Hymenophyllum wilsonii (Wilson’s Filmy-fern) and Vaccinium vitis-idaea (Cowberry) were in a number of sites – and elsehere in the general area.  Lathyrus linifolius (Bitter-vetch), Thalictrum alpinum (Alpine Meadow-rue) and Trollius europaeus (Globeflower) await another visit (maybe).

Holly had mines of the fly Phytomyza ilicis (Holly Leafminer) and on dead leaves the spore bodies of the fungus Trochila ilicina (Holly Speckle), the latter being apparently the less frequent locally.

This fungus growing on a long-dead detached lump of unidentifiable tree looked distinctive but so far I haven’t a clue as to its identity:

 

 

Fungus on Figwort

March 22, 2019

Scrophularia nodosa (Common Figwort) is common enough locally and grows in my garden as a weed. It does not spread too much and I am always happy to let a few specimens flourish. A while back I noticed that last year’s capsules had small black dots on them and a few days ago I took some images and sent them to Bruce who tells me it is Didymella commanipula. He says it supposed to common though he has never seen it. There are only two records on NBN and seven on FRDBI (Fungal Records Database of Britain & Ireland) with none from Scotland on either database. If it is common it appears to be massively under-recorded.

Rare Fungi

September 6, 2018

I found this on dead stems of Schoenoplectus lacustris (Common Club-rush) at Loch Lonachan last month:

Bruce says it “seems to be the imperfect stage of Myriosclerotinia scirpicola.  This is rare and most interesting.”

The Crinodendron hookerianum (Chile Lantern Tree) at Dunvegan has leaf spots and these just may be new to science – they have certainly floored Bruce even after a literature search.

Seth has kindly agreed to get a specimen to Bruce who will send it to Kew.

Update: Bruce thinks it is Phyllosticta crinodendrin, apparently not previously recorded outside South America.

Thursday

September 2, 2018

On Thursday I joined Skye Nature Group’s excursion to look for fungi, though as usual we looked at other things as well. Near the Crinodendron hookerianum (Lantern Tree) we found a fairly mature Cupressus macrocarpa (Monterey Cypress) and a Laburnum looking pretty sick with fungi growing out of it. This one is clearly not the hybrid as it had many seeds per pod and I think it is Laburnum alpinum (Scottish Laburnum). In an ideal world I will go back a bit earlier next season to make sure.

I also spotted Erica vagans (Cornish Heath):

 

There must be something about SNG meetings as it was at the very first one last October that we made the first localised record for this plant in the vice-county.

The fungi were many and various and Seth has written the visit up here. Here are just a couple to whet your appetite (or not):

 

Afterwards I went to the Knott area to check a few things and found Origanum vulgare (Wild Marjoram) – the herb sold as Oregano – by the roadside, obviously escaped or thrown out from a garden. I find it spreads rapidly by seed in my garden.

I took my grapnel to a nearby loch to find out what the pondweed was in the middle of it. Even from the shore back in June it was clearly not the usual Potamogeton polygonifolius (Bog Pondweed) or Potamogeton natans (Broad-leaved Pondweed). It turned out to be Potamogeton perfoliatus (Perfoliate Pondweed), so nothing exotic.

I also took a specimen of the Inula hookeri (Hooker’s Fleabane) to check whether it is actually I. orientalis (Georgian Fleabane) as Mike had pointed out that they are very similar. However, both his and my searches for glandular hairs have been inconclusive – the relevant key in Sell & Murrell being ambiguous. It may be possible to sort this out later from achenes.

Glenmore

September 2, 2018

Glenmore, south-west of Portree, is in a tetrad that needed more work so yesterday I had a go. The Glenmore River joins the Abhainn an Acha-leathain to form the River Snizort within the tetrad of interest and there is the roadside and an extensive area of bog, so even though it is now September I came away with 159 vascular plant records including Utricularia minor (Lesser Bladderwort) still in flower (or in flower again):

Utricularia minor (Lesser Bladderwort)

This leaves 14 tetrads in VC104 that are >5% land but have fewer than 50 post-1999 records. A further 28 have 50 to 79. (“Land” includes freshwater bodies.)

Also, there was Pustula tragopogonis on Cirsium heterophyllum (Melancholy Thistle) which I have only seen once before:

Waternish

August 26, 2018

Geary Ravine is one of our riches botanical sites on Skye but yesterday I reached the top end of it and turned my back so as to record what looked like a seriously dull tetrad. At different times Carl (2006) and I (2012) had made a few records whilst passing through. We had amassed a total of 47 taxa.  The best bet to improve that score seemed to be to walk up the Abhainn a’ Ghlinne and indeed after half an hour I had added a further forty. Four hours later the taxa count was up to 111.

I also made a foray into NG26K to the south and at the top of Ben Geary I found Salix herbacea (Dwarf Willow), new to NG26 and infected with Rhytisma salicinum (Willow Tarspot).

Additionally, some leaves had clearly been browsed by something small:

There were masses of Twin-Spot Carpet moths but most pleasing was a Common Lizard making use of the only piece of litter I saw to warm up:

It had clearly regrown its tail at some point.

I did quite well for invertebrate and fungus records, but nothing of great rarity.
