An enthusiastic group of a dozen naturalists met at Folly Farm in glorious autumn weather, for a day spent studying a wide range of plants, fungi and lichens. We started by looking at lichens on Ash and Oak bark, Spangle Galls on Oak and the amazing pure white sputnik-like egg sacs of a small spider, Paidiscura pallens on the underside of Oak leaves. Walking through Folly Wood, members were introduced to some common mosses, including an explanation of alteration of generations and the difference between acrocarpous mosses (upright plants bearing their capsules at the apex of shoots) and pleurocarpous mosses (sprawling plants bearing capsules along the length of the shoot). During the morning we examined several species: Catherine’s Moss (Atrichum undulatum), a typical acrocarpous species; Common Pocket-moss (Fissidens taxifolius), an acrocarpous moss with distinctively flattened prostrate shoots; Common Feather-moss (Kindbergia praelonga) and Rough-stalked Feather-moss (Brachythecium rutabulum), both pleurocarpous mosses growing on logs; Crisped Pincushion (Ulota crispa), a small cushion-forming epiphytic acrocarpous moss, and Lateral Cryphaea (Cryphaea heteromalla), an epiphytic pleurocarp with appressed primary shoots, but projecting secondary shoots bearing capsules. Later, we also saw Neat Feather-moss (Pseudoscleropodium purum), Fox-tail Feather-moss (Thamnobryum alopecurum), resembling small trees, and Slender Mouse-tail Moss (Isothecium myosuroides) clothing the lower parts of tree trunks.
The main focus of this autumnal walk was fungi, of which we saw a good range. We soon encountered Blushing Rosette (Abortiporus biennis), with its rose-like fruit-body, and Snapping Bonnet (Mycena vitilis), with its stem which breaks with an audible “snap”. Later we found other species in this genus: the Burgundydrop Bonnet (Mycena haematopus) which weeps a dark red latex when broken and the Grooved Bonnet (Mycena polygramma) with longitudinal striations on its stem. A number of bracket fungi were seen, including the Hairy Curtain Crust (Stereum hirsutum), Trametes ochracea, the Peeling Oysterling (Crepidotus mollis) and an impressive Beefsteak Fungus (Fistulina hepatica) on a splendid oak. This tree also supported the Bleeding Oak Crust (Stereum gausapatum) and Peniophora quercina, both crustose species which grow on live wood. Perhaps the most exciting mycological find was a colony of false truffles (Melanogaster broomeianus) beneath a Beech tree, closely attended by bright yellow and grey- brown baby fruit bodies of Rooting Bolete (Boletus radicans). Other species seen included the Willow Shield (Pluteus salicinus) and Deer Shield (Pluteus cervinus), the extremely variable Deceiver (Laccaria laccata), a tiny Orange Mosscap (Rickenella fibula), the White Knight (Tricholoma album) and the poisonous White Fibrecap (Inocybe geophylla). In woodland we found the Grey Milkcap (Lactarius vietus) and marvelled at the quantity of milk emerging from the gills when damaged. Along a log we saw a host of Pale Brittlestems (Psathyrella candolleana), whilst on dung in the grassland we found the Petticoat Mottlegill (Panaeolus papillionaceus), the delicate little Hare’s-foot Inkcap (Coprinella lagopus) and the Fairy Inkcap (Coprinellus disseminatus). We found three different slime moulds, one a brilliant yellow, another a group of small grey spheres.
Members discussed the shortage of butterflies this year. During the day we saw Speckled Wood, Red Admiral and a smart Comma; however the highlight of the whole day was a Clouded Yellow, the first of the year for many. We also saw a Large Yellow-underwing and a Pale Emerald moth.
Folly Farm is a wonderfully diverse site with a varied flora. Deep ravines in woodland support luxuriant ferns, mostly Soft Shield-fern (Polystichum interjectum) and Hart’s-tongue (Asplenium scolopendrium). We also saw Male Fern (Dryopteris filix-mas), Lady Fern (Athyrium filix-femina), Broad Buckler-fern (Dryopteris dilatata) and Intermediate Polypody (Polypodium interjectum). Devil’s-bit Scabious (Succisa pratensis) was flowering, providing an important late nectar source; we also saw Betony (Betonica officinalis), Knapweed (Centaurea nigra) and Agrimony (Agrimonia eupatoria) in flower. A hay meadow which had been cut in July was dotted with Autumn Hawkbit (Scorzoneroides autumnalis), another important native late nectar source.
The whole day was filled with the study and appreciation of diverse natural history, made richer by the varied interests of the members present. All agreed that it had been an interesting and enjoyable day, enhanced by the glorious autumn sunshine.

On the morning of Wednesday 31st August a group of around 24 members met at Friary, Hinton Charterhouse, by kind invitation of Penny Williamson. Penny has lived at Friary for about 5 years and has a keen interest in the conservation of the area.
Penny explained a bit about the history of The Friary, including recent research conducted by The University of Sheffield. A surprising finding of this research was the extensive stone building work for use by members of Hinton Priory.
Penny also was very generous in providing refreshments and lunch for the group. So after tea, coffee and biscuits we set off on the footpath towards Freshford. First stop (for the more adventurous) was to explore slightly off the path to look at the site of an old cottage. This cottage, with no running water or electricity, was occupied by a lady called Mercy Swift up until the 1960s. Along the way we then noted some of the wild flowers that were out (greater chickweed, bush vetch and teasels), and looked at various lichens on branches. Marion Rayner also collected some leaf skeletons, which were particularly admired by my two young children!
Once in Freshford we walked down to the river, hoping for a sighting of a dipper. Although they are common here, we didn’t see one. We were treated however to the more unusual sight of a day-flying bat. It was circling under the tree, low enough for everyone to get a good view. Geoff Hiscocks kindly forwarded a reply to a letter he had from BBC Wildlife in 2009 explaining that day flying bats are more common than you think. Hunger and thirst can force them to fly in the day, when they are more vulnerable to predatory birds.
After a delightful lunch of quiche, salad, tiramisu and ice cream, we walked towards Iford through woodland and along the riverside. Notable finds included a bright yellow slime mould (Fuligo septica), a Pine Ladybird, Fringed Polypore (Polyporus ciliatus), Alder Bracket (Inonotus radiatus) and Alder Tongue Gall (caused by the fungus Taphrina alni). Back near the car park, where the brook cascaded over stonework, Alan and Marion Rayner were pleased to find the beautiful Curled Hook-moss (Palustriella commutata) growing profusely. Overall, a very successful meeting in an interesting location.
