Strathrory Burn – 12 September 2015

Monday, September 14th, 2015


The Tain & District Field Club enjoyed the prospect of beating the forecast rain while searching for wolf spiders along the sandy / gravelly banks of this burn. The forecast proved about right so it was wet weather gear all-round, but the specific target species Arctosa cinerea did not appear. Of course, lack of evidence does not provide evidence of non-existence, so future searches may be worthwhile.

TDFC members, as ever, observed and recorded many species which will add to the known assemblage in our area.

Here is a species list :

HELP NEEDED WITH ROSS-SHIRE FUNGUS SURVEY

by Mr B. Ing, Ullapool

Since 2004 I have been compiling records of fungi (all groups) from Ross-shire, v.c. 105 and 106. Historical records,
from literature and herbaria, have been augmented by a systematic programme of fieldwork.

With 98 whole or part 10km grid squares covering the area I am aiming at geographical as well as mycological
coverage. A ‘target’ of 100 species per 10km square has been adopted, although the better-worked squares have far
more than this. 72 squares have now reached their target! 10 of the remaining 26 are difficult of access.  (Note – for
hectads only partly in VCs 105 and 106 the target is <100 species – actually the number of 1km squares in the VCs.)

The list below is arranged as follows: grid square/target/number of species recorded/ species required/notes of likely
sites, accessibility etc. Any help with records, whether macrofungi; mushrooms, brackets, puffballs etc., plant
pathogens: mildews, rusts, smuts, leaf spots etc, or ascomycetes on soil or wood, will be gratefully received and duly
acknowledged in the proposed publication.

Whooper Swans near Fearn Aerodrome

Sunday, November 2nd, 2014

A huge build up of Whooper Swans (Cygnus cygnus) at the moment in the Loch Eye area. 2726 counted today. Around 2400 are on the Clay of Allan, along with a Black Swan and lots of geese. Another 130 down towards Kildary and 190 near Portmahomack. Thanks to Bob for the info.

Beached Pilot Whale – Tain Bay

Saturday, November 1st, 2014

A Long-finned Pilot Whale (Globicephala melas) stranded and died in Tain Bay on the afternoon of 25 October 2014.

Click image to viewThe whale was not able to be refloated and sent back to deep water.  An autopsy will hopefully provide some indication of why this whale stranded and died.

Mushroom with slug / worm eggs?

Wednesday, August 27th, 2014

In a good year for mushrooms Chanterelles were a target for the menu on Wednesday, 27th August 2014.  After years of finding mushrooms this example turned up – not before seen by us here nor anywhere.

The black eggs are …… ?  There may be an answer at iSpot.

Chantarelle with Slug Eggs?  Or Worm Eggs?Click image to view

ChantarelleSlugEggsDSC07195

ChantarelleSlugEggsDSC07186

EDIT 30/08/2014: There are responses which indicate the black blob objects on the mushroom are a slime mold; iSpot likely belonging to the group Myxomycetes or plasmodial slime molds, possibly Leocarpus fragilis (1), (2), and elsewhere, astonishingly similar to Leocarpus: Trichia decipiens.

In 2012 I asked about ‘insect eggs’ in tree bark. Maybe that was a similar slime mold!

Keep checking this post to see if an answer emerges.

2014, July, Noctilucent Clouds

Wednesday, July 9th, 2014

Spaceweather.com, and other observers, predicted that Noctilucent Clouds may be visible in early July 2014. From Ardgay the evening sky “just looked right/promising”.

In the night of 7th July both Phil in Ardgay and Pat in Balintore were, for an unknown reason, looking at the northern sky and saw noctilucent clouds at about 01:30 +/-. The view was basically to the north, in Ardgay slightly eastward.

Here are their proofs:

Simplified Geometry for observing NLC’s

Noctilucent Cloud Sighting Geometry

Spaceweather.com has this to say about Noctilucent Clouds:

NLCs are Earth’s highest clouds. Seeded by “meteor smoke,” they form at the edge of space 83 km above Earth’s surface. When sunlight hits the tiny ice crystals that make up these clouds, they glow electric blue.

In the northern hemisphere, July is the best month to see them. NLCs appear during summer because that is when water molecules are wafted up from the lower atmosphere to mix with the meteor smoke. That is also, ironically, when the upper atmosphere is coldest, allowing the ice crystals of NLCs to form.

The natural habitat of noctilucent clouds is the Arctic Circle. In recent years, however, they have spread to lower latitudes with sightings as far south as Utah and Colorado. This will likely happen in 2014 as well. Observing tips: Look west 30 to 60 minutes after sunset when the Sun has dipped 6o to 16o below the horizon. If you see blue-white tendrils zig-zagging across the sky, you may have spotted a noctilucent cloud.

It seems our ’sunset / sunrise’ lasts all night as far as seeing phenomena like noctilucent clouds.  It just remains for you be awake, there to be few obscuring clouds, and tiny ice crystals at just the right position between you and the sun.

Moonwort, Botrychium lunaria

Monday, May 19th, 2014

Moonwort, Botrychium lunaria, is presently abundant on Nigg dunes, as seen by David.

If you haven’t seen Moonwort (Botrychium lunaria) the small grassland fern, it is present in profusion at Nigg dunes at the moment (NH 802 689).
It is easiest to find along the edges of the path in the slightly loner grass areas.

2014 Aspen Catkins

Tuesday, April 15th, 2014

It is not since 2010 that breeding Aspen has been seen locally – SEE HERE.  On April 14, 2014 a single Aspen was seen near Ardgay with a good display of male catkins.

There are many Aspen stems in the area but none other than this one show any sign of catkin flowers.  It may be time to start noting whether any other Aspen will flower this year.

April 19; about 200m away from the Aspen stem above another showed signs of catkins (photo below).  These are female flowers and are so far restricted to only a few upper branches.

2014, The February Sky

Monday, March 3rd, 2014

During February (at least) two interesting phenomena were seen in our skies.

In the evening of 27th February the notable aurora display seen over much of the UK was the stand-out evening sight this month!

More regular, and predictable, was the silent, early morning conjunction of Venus and the Moon. A clearing in the southeastern sky was needed – and such clearings were rare.

Colour-ringed Shags – Lecture

Saturday, January 18th, 2014

We had an extremely interesting and informative talk by Jane Reid on Tuesday, 14 January, 2014.

Jane asked that members look out for colour ringed shags and record colour and letters from rings if possible. The rings can be read with a telescope. Details in the attached photo.

Beechmast Candlesnuff fungus

Saturday, January 18th, 2014

We found the Beechmast Candlesnuff fungus (Xylaria carpophila) this morning at Calrossie. Heather found it below the leaf litter within 2 minutes of leaving the car and about 20 secs after starting to search! Photo attached.

Those who weren’t at Tuesday’s meeting can find info about this fungus on the HBRG website news page (http://www.hbrg.org.uk/Latest.html)

Perseid Meteors, August 2013

Saturday, August 10th, 2013
Despite the fuss the press is making the predictions are not for an outstanding display this year but the Perseids are always good even in an average year.
The best night should be Monday (12th) when there could be up to 100 per hour.
There is good information on the Armagh Observatory website:
http://star.arm.ac.uk/press/2013/Perseids2013_pr.html
You can also find details (among the adverts) at Meteor Watch:
http://www.meteorwatch.org/
And slightly more technical at:
http://meteorshowersonline.com/perseids.html
This is an American site but gives details for all over the world – so make sure you are reading the northern hemisphere information!
