Forays Reports 2016 (in reverse order)

NFG Foray Daneshill Lakes LNR May 14th 2016

About 16 members and visitors gathered in the car park on a fine morning that turned out to be quite warm by the end. Rain had fallen a few days earlier, so we hoped for reasonable numbers of fungi on a site that had proved very productive the previous autumn. By the end we had probably recorded more than 35 fungi and lichens, which is good for this time of year. When the list is complete, members can obtain a copy from Diane, our recorder.

One of the mushrooms we found ubiquitous here was St George's Mushroom, Calocybe gambosa. It occurred all over the site from woodland to lake edges, in various stages and ages. That most frequently recorded of all macrofungi, Sulphur Tuft, Hypholoma fasciculare, duly made its appearance in the wooded area. Other mushroom types were Scurfy Twiglet, Tubaria furfuracea and its cousin under hawthorn, Tubaria dispersa; Pine Conecap, Strobilurus tenacellus in needle litter; Fleecy Fibrecap, Inocybe flocculosa with willows & birch; and, most interestingly, Shield Pinkgill, Entoloma clypeatum, a medium to large toadstool found under hawthorns in springtime.

Some brackets & crusts were recorded including: Southern Bracket, Ganoderma australe, on hawthorn; Trametes ochracea on willow; and a soft poroid bracket, Bleeding Porecust, Physisporinus sanguinolentus, on rotten wood. As its name indicates, it bruises bright red before browning when damaged. I have seen it only twice before in the county.

We found only one cup fungus, but it was an uncommon one which grows from spring to autumn and was collected from damp, sandy soil under willow & hawthorn - Peziza ampliata - smallish cups, very pale beige to brown with finely toothed margins and a scurfy-granular exterior. Richard found it three years ago at Rushcliffe, so this is a 2nd county record.

On a dead nettle stem John Brown spotted some minute stalked discs, which proved to be the common and pretty Crocicreus cyathoideum. On the pre-walk a few days before, I found some even more minute cream discs on the brown buried base of a bracken stem, Psilachnum chrysostigma. That one needed digging out. Various other microfungi were recorded on dead twigs, stems and leaves including: Septoriella junci on soft rush, a 1st Notts record; and Stagonospora typhoidearum on a waterlogged Typha stem, a 2nd Notts record but the first since the 1960s. Good to know it's still around. Sycamore Tarspot, Rhytisma acerinum, is commonly recorded on most forays, but it has a far less common cousin on goat willow leaves, Rhytisma salicinum. This was found by Diane. There are almost 7000 records for Rhytisma acerinum, but only 200 or so for R. salicinum.

Daneshill lakes, new to us as a Group last year, is a very rewarding fungal site.

Gedling House Wood April 24th 2016

Our first foray of the year was well attended with 18 members, the chair of "Friends of Gedling House Wood", his wife and a visitor. We hadn't visited for some time but it was a worthwhile visit with a list of 28 fungi and 19 lichens expertly identified by Craig.

It was a very pleasant morning and the first species identified, before we even entered the wood, was found by our visitor on ivy. He identified it as Phoma hedericola which causes whitish spots with wide brown borders on living leaves. It was quite dry in the wood so there were not perhaps as many fungi as usual but this was recompensed by the lovely display of spring flowers. There was a large area of Three-cornered Leek Allium triquetrum; probably a garden-escape but attractive and useful for insects at this time of year.

We saw three types of Stereum during the walk. There was the yellowing curtain crust S. subtomentosuum, the broadleaf bleeding curtain crust S. rugosum, and the hairy curtain crust S. hirsutum. The bracket fungi found included an old specimen of the Blushing Bracket, Daedaleopsis confragosa, the Hoof Fungus Fomes fomentarius, and Turkey tail Trametes versicolor. The blushing wood mushroom Agaricus silvaticus was found growing under a sycamore tree. This is not the usual time of year to find this but it is a very common woodland fungus.

The date was right for St George's Mushroom Calocybe gambosa and this was found in a nettle bed under the Hawthorns in the meadow area by Ann and Mary Also under these trees Ann found Monilinia johnsonii a small cup-like Ascomycete fungus that grows on buried Hawthorn berries. I was looking out for small things and found Violet Bramble Rust Phragmidium voiolaceum in the uredinia stage which is orange on blackberry and Bitter Chocolate Rust Uromyces ficariae on Celandine.
