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.

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, 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:

Glen Scaladal, Strathaird

September 2, 2018

Both Steve and I visited Glen Scaladal, Strathaird during August and whilst there was a fair bit of overlap in what we recorded, we both found plants that the other didn’t. Two tetrads with rather few post-1999 records are now well recorded.

We both found Scutellaria minor (Lesser Skullcap), something that is always easier to spot late on when in flower:

And I found a rose that I think can only be Rosa x margerisonii (Rosa spinosissima x caesia):

There was Osmunda regalis (Royal Fern) in several places on the sea cliffs:

and Belemnite guards galore in the rocks:



Matt tells me the near vertical Belemnite shows the guard with the alveolus at the bottom where the chambered phragmocone would sit.
