Talk: 23 January 2018 Andy Page: Raptors of the New Forest



We can expect an excellent talk tonight, for Andy Page works for the Forestry Commission as Head of Wildlife Management South England Forest District. Raptors are a particular interest and expertise, which he has used to great effect with his involvement in the setting up of the Goshawk nest cameras at the Reptile Centre near Lyndhurst.

Talk: 28 November 2017 Fungi in the New Forest



Sara Cadbury captivated the audience with her talk on New Forest fungi. Sara, an expert mycologist and member of our own Naturalist Society started with the identification of fungi including the difficulties that this involves due to mycology being a rapidly advancing science, hence the names in the identification books are often out of date. Identification is a calculated guess without the use of a microscope. Identification is based on habitat ( both woodland/grassland, also which tree /plant it is attached to ) ; size; colour ( also difficult as some colours are water soluble); colour of spores, smell and if it has a cap or gills. Sara showed us the cocoa coloured spores of the large Ganoderma fungi found in the forest.

Broadly fungi can be divided into two groups- Basidiomycetes, which drop their spores, examples being Boletus fungi, and Ascomycetes, which shoot their spores out, examples being cup fungus and green oak cup.

Sara had photographs of spores, showing the variation in size, shape, ornamentation and spikes and the means of measuring these microscopic spores. The microscope also revealed the structure, named a basidium, of the Basidiomycetes, which have usually four arms at the apex, each of these arms has a spore attached. These spores are immature, and for identification purposes cannot be measured until unattached. In the Ascomycetes the spores are in asci, and when ripe they shoot out of the top.
Next we looked at Ergot, which occurs mainly on cereal crops, usually rye. These fungi used to cause death, as the fungi were incorporated into flour and then onto bread. The poison within the Ergot caused constriction of capillaries, leading to gangrene and death. The symptoms involved itching of the extremities and hence the disease was named St Vitus dance.

A spalted bowl
Sara bought along many examples of spalted wood, which is greatly favoured by wood turners, due to the black lines that are so decorative in the finished bowls. These black lines are war zones where two fungi, of either similar or different kinds are defending their territory. Between these two lines there is often a further fungus growing. The Porcelain Fungus can produce a yellow line in these circumstances.

Sara then spoke of a number of different and interesting fungi to be seen in the forest. Stinkhorn has an unusual spore dispersal as the smell it emits attracts beetles and flies, which the disperse the spores. Usually spores are wind dispersed.

Devil's Fingers
Forest specialities include Clathrus archeri, Devils Fingers, which occur on Setley Plain, their spore dispersal is also by flies and beetles. Poronia punctate, Nail Fungus, occurs on manure from New Forest ponies that have poor nutrition and diets high in roughage. Hericium erinaceus, Bearded Tooth, Hericium caralloides , Coral Tooth and Hericium cirrhatum, Tiered Tooth, are all rare but do occur on beech trees in the forest.

Sara explained that the large diversity of fungi in the New Forest is due to the variety of habitats, from the Headon beds south of the A31 to the sands and gravels in the north.
Sara was particularly interested in the numbers of fungi with parasites themselves- showing us photographs of Peppery Boletus fungi being parasitic to Fly Agaric. Earth balls and puff balls also have parasites. We finished with photographs of Chicken in the Woods, Dyers Mazegill, Magpie Fungus, wax caps and Wood Blewit.

Sara was warmly thanked by a full audience of members and visitors. Visitors are very welcome at both the evening meetings and our walks throughout the year. Details to be found on our website www.lymnats.org.uk

07 January 2018 Keyhaven Bird Walk


The first Sunday bird walk of the year saw nine hardy souls turn out at Keyhaven in a bitterly cold strong north-easterly wind but with mostly clear blue skies as some compensation. We followed our usual route from Keyhaven along the sea wall then returning via the Ancient Highway.

A female Pintail followed by a pair of Shoveler
We began our walk a couple of hours after low tide which meant plenty of mud in Keyhaven harbour for the probing Dunlin, Common Redshank, Black-tailed Godwit and Grey Plover; out on the water were Little and Great Crested Grebes, Red-breasted Merganser and Brent Goose.


On the lagoons numbers of birds were unusually low and most of those that we did see were hunkered down sheltering from the wind. However we managed to add a number of duck species to our list – Teal, Wigeon, Shoveler, Pintail, Shelduck - and the low angle of the sun meant that their colourful plumage was visible at its best.

Brent Geese in flight
Overhead a large flock of Golden Plover and Lapwing swirled back and forth in flight but we didn’t see what had disturbed them. Brent Geese also took to the air a number of times; it’s always a pleasure to hear them calling constantly to each other either in the air or on the water.

Grey Heron, Little Egret and Wigeon sheltering
Small birds were few in number though we did manage to note Stonechat, Reed Bunting, Pied Wagtail and a snatch of Cetti’s Warbler song along the Ancient Highway where there were good numbers of water birds on the balancing ponds, perhaps because it was a little more sheltered there.


Overall we noted 42 bird species during the morning plus a couple of Roe Deer browsing on the marsh beside Fishtail Lagoon. MF

23 December 2017 James' Hill



Leucobryum glaucum
Despite the gloom and proximity of Christmas, 17 turned up for this 2.5 mile walk, taking in deciduous woodland, boggy clearings and a bit of local history along the way.

We headed SW on grassy paths, muddy and ill-defined at times with little of note at first. At last some fungi, mosses, lichens and elusive birds were spotted. Robin, Blackbird, Chaffinch, Blue Tit, Great Tit, Long-tailed Tit, Nuthatch, Mistle Thrush, Jay, Carrion Crow, Great Spotted Woodpecker, Woodpigeon and Stock Dove were all present. Leucobryum glaucum, formed green cushions on ground and logs. If knocked over, this moss can grow through its base and re-establish itself. Various fungi were identified including bright Green Elf Cup, pale and gelatinous Beech Jellydisc, Turkeytail, Oyster Mushroom, yellow and scaly Gymnopilus junonius, and King Alfred’s Cakes.
Turkeytail

Our path descended to the Cut Walk, a straight track following the line of a road built in 1725 for the Duke of Bolton, Lord Warden of the Forest who lived in Burley Lodge, to make his journey to Swan Green more comfortable. A short diversion led to the beautifully arched, brick ‘Roman’ Bridge over Highland Water, also about 300 years old and thought to be on the site of a roman road.

We turned back and headed northeast along the Cut Walk until we reached the garden wall of Allum Green House. This small settlement has attractive dwellings where Vera Brittain, WW1 nurse, author, feminist, pacifist and mother of Shirley Williams, lived with her family for a while and where a stray bomb killed 4 Royal Army Ordnance Corps men in 1940. Here we turned north crossing areas of boggy, open ground back to the road near White Moor then east to James’ Hill. MW/SP
