Caterpillar & Fern

March 26, 2017

Nick reports Hymenophyllum wilsonii (Wilson’s Filmy-fern) from Allt Daraich where I failed to re-find it based on an old record, just over a year ago.

I found this moth larva whilst doing a bit of spring tidying in the garden:

larva 170324

Nigel tells me it is the larva of the Large Yellow Underwing – a moth I often get in the moth trap later in the season. It apparently comes in brown and green forms.

Tree Diseases

March 26, 2017

I went to an interesting pair of talks on tree diseases at the HBRG Spring Meeting yesterday by folks from Forest Research.  There is much useful information at the Observatree and Forestry Commission’s Pests and Diseases websites.

We know all too well about Phytophthora ramorum on Larch on Raasay – so it may be elswhere. Also Phytophthora austrocedrae which causes dieback and mortality of juniper may be worth looking out for. It is not known locally but the population of potential human observers is low.  That’s potential observers rather than potential humans.

If you see something worth reporting, they would like three photographs – of the tree, the infected area and a close-up, as well as a grid ref etc.

Raasay Fungi

March 15, 2017

Back in October 2014 I put an image of a bracket fungus from Screapadal, Raasay on this blog. Recently, Neil Mahler has suggested that it is Stereum subtomentosum (Yellowing Curtain Crust). You can see his comments on that post.

If this is right, it looks like being the third record for Scotland – see the distribution map on the NBN. Bruce Ing also says he thinks that is the right identification, though he is not 100% sure, and tells me that it came into the UK from France in the 1960s.

Meanwhile, Bruce has confirmed Phomopsis leycesteriae growing on Leycesteria formosa (Himalayan Honeysuckle) in my garden. It is probably common wherever this shrub grows – and it has spread into the wild on Skye and the mainland nearby. Indeed, my interest in this was stirred by Murdo finding it near Plockton and asking me to identify the host plant.

Whisky Fungus

March 2, 2017

Baudoinia compniacensis grows faster in the presence of alcohol and is found in and near distilleries. It causes the distinctive blackening of warehouses in Cognac and Scotland. Until recently there was only one official mycologically approved record from Scotland but a bit of effort my members of HBRG has improved that:

My modest contribution is that dot on Skye as it is present at Carbost on trees near the Talisker distillery – I found it on Beech, Hawthorn & Sycamore.

My thanks to Bruce Ing for identification.

Raasay Willows

My contribution to Am Bratach: Raasay’s Community Newsletter concerns willows and can be found via a link on this page.

The picture captions didn’t make it so here they are:

Bluebells and Orchids

March 1, 2017

My first bluebell of the year:

bluebell-tomar

Hyacinthoides hispanica

though I have had to travel 1250 miles south to see it. This also explains Ophrys tenthredinifera  Sawfly Orchid (probably) today:ophrys-tenthredinifera-tomar

Greetings from Tomar, Portugal to all my readers!

Hawkweeds

January 28, 2017

I have been a bit remiss about Hieracium spp. (Hawkweeds) over the years, generally recording them as the aggregate and occasionally sending a few for expert determination. Last year I collected eleven from Raasay and Skye and recently sent ten of them away having lost one. It probably got thrown out accidentally in a grand clean-out, but could yet turn up.

The results came back immediately from David McCosh and turned out to be of six different microspecies of which the most interesting is H. praesigne (Distinguished Hawkweed). I don’t know whether the vernacular name refers to its dignified appearance or whether it was named in frustration by someone finally sorting it out from similar species.

This turns out to be only the eighth record for Scotland – and the second for the east coast of Raasay. It was previously recorded by Alan Stirling in 1969 at Druim an Aonaich, 4 km north of the new site and in a different 10 km square of the National Grid.

Here is the one that got away:

East side of Loch Harport

January 26, 2017

Today I ventured into NG3635 on the East side of Loch Harport from the estuary of the Sumardale River south-eastwards.I was hoping to re-find Hymenophyllum wilsonii (Wilson’s Filmy-fern) from 1967. Success:

hymeophyllum-wilsonii-lr

Hymenophylum wilsonii

and also Juniperus communis (Juniper), Osmunda regalis (Royal Fern), Polystichum aculeatum (Hard Shield-fern) from 1977. I found two out of three:

I recorded 83 taxa of which 6 were new to the tetrad and 16 had not been recorded since before 2000.

Second Half of 2016

January 26, 2017

A report on the last six months of 2016 is on the VC104 page of the BSBI website. It adds nothing to what has been reported here. It was perhaps the thinnest six months for several years in terms of exciting new discoveries, mostly because I tended to be away from the area whenever the weather was fine and home when it was filthy.
