Oudemansiella …

Porcelain Fungus (Oudemansiella mucida)


O. mucida is a widespread and common beech wood species. Appearing in late summer to late autumn it is typically found on rotting beech trunks and fallen branches where it grows in clusters. It is semi-translucent, slimy and white in appearance. When O. mucida is found on a beech tree it usually outcompetes other fungi nearby by means of a powerful anti-fungal agent called strobilurin. It is saprobic [deriving its nourishment from non-living or decaying organic matter] or weakly parasitic to living beech trees. While it has a strong connection to beech, it has also been found growing on oak on rare occasions.

The above group was recently photographed around three metres up a mature beech tree.

Not a bee in sight…

Beeswax Bracket (Ganoderma pfeifferi)


G. pfeifferi is a widespread but uncommon find in England and very rare in Scotland and Wales. The above group was recently found and photographed in a cavity within a decaying beech in West Sussex woodland. My thanks to Martin Allison, county recorder for basidiomycetes, for confirming identification.

Simocybe ...

Simocybe sumptuosa




Little brown jobs are often far more than that when viewed through a macro lens. The above specimens of the delicate S. sumptuosa were recently found and photographed on a rotten oak log at Wiggonholt Common, West Sussex. My thanks to Martin Allison, county recorder for basidiomycetes, for confirming their identification.

Fungi that bite ...

Velvet Tooth (Hydnellum spongiosipes)




H. spongiosipes (Thelephorales: Bankeraceae) is an uncommon stipitate hydnoid fungus. These are a group of ‘tooth fungi’ [fungi that release their spores from tooth-like structures], which have a short stalk or 'stipe', hence the name 'stipitate'.

Stipitate hydnoid fungi are ectomycorrhizal; forming close symbiotic relationships with trees and deriving some of their nutrients from the tree's roots. This aids them in obtaining nutrients where soil quality is poor and means they are always found in association with trees. H. spongiosipes is typically associated with oak, sweet chestnut and, less frequently, beech; this provides a useful, but not necessarily accurate way of distinguishing between this species and H. ferrugineum, which occurs mainly under pine.

Variation in concept …

Sowerbyella radiculata

Until someone calls it something else …




The British Mycological Society records 124 British records of S. radiculata (Pezizales: Pyronemataceae) on its FRDBI database [18 October 2017] with just 5 from Sussex; the most recent being in 1957 from Friston Forest, East Sussex. There are two early records, one dating back to 1876, from Stopham, West Sussex. However, S. radiculata has also been recorded from Lullington Heath, East Sussex, where it was first recorded in 2014. There is also a modern record from Ashdown Forest, East Sussex (M. Allison, 2017, pers. comms., 14 October).

Buczacki et al. (2012) state, ‘usually in small trooping-tufted groups’ and ‘on soil with conifers.’ Sterry et al. (2009) state, ‘solitary or in small groups in coniferous woodland.’ The above specimens were found amongst coastal chalk grassland in East Sussex; so quite distinct in habitat from that described. There is a lot of variation in the current concept of this uncommon species, including a few ‘varieties’, which will no doubt be described as separate species in the future. Apart from the untypical habitat in which the above examples were found, the spores are quite wide and have a nice dense reticulate ornamentation; shown above dyed with Cotton Blue.

My thanks to Nick Aplin for the above photomicrograph and his considered opinion.

Cnoc Salltraim ...

Cuckoo (Cuculus canorus)




C. canorus is a familiar herald of spring and a species that is thinly distributed over a wide breeding range throughout most of Britain, Europe and the Palearctic. It is a fairly common but rapidly declining summer visitor to Sussex, where the males commence singing soon after their arrival; typically in early April. Recent satellite tracking technology has shown that the males usually leave the UK to their wintering area south of the Sahara only a few weeks after first arriving here in the spring.

C. canorus has a well-known breeding strategy as a brood parasite, laying its eggs in the nests of other birds; typically those of the Dunnock (Prunella modularis), Meadow Pipit (Anthus pratensis), Pied Wagtail (Motacilla alba) and Reed Warbler (Acrocephalus scirpaceus) in the UK. The female, who will specialise in one particular host species, will only ever lay one type of egg and will always target her egg-laying appropriately. The genes for egg pattern and colour are thought to be carried on the female chromosome, so they are passed down from mother to daughter regardless of who the female mates with. This means that a Cuckoo targeting a Reed Warbler always produces eggs with a Reed Warbler pattern and she knows which nests to target thanks to the process of imprinting. As a young chick, she will have learned to recognise the song and appearance of her foster mother; and as a returning adult she will seek out the nests of females that match this mental image and lay her eggs accordingly.

The above images of a female were recently taken on North Uist in the Outer Hebrides.

Balranald …

North Uist, Outer Hebrides, 13 to 27 May 2017






Balranald Nature Reserve incorporates the most westerly point of the island of North Uist, the Aird an Rùnair peninsula, looking out to the Monach Islands and the magnificent St Kilda archipelago. It is a Site of Special Scientific Interest (SSSI) and is designated as a Wetland of International Importance (Ramsar).

This beautiful Hebridean reserve comprises 658 hectares [1626 acres] of rocky headland, islands, sandy bays, dunes, grasslands, freshwater lochs, fen and the flower-rich species diverse machair. Machair is a rare, bio-diverse coastal grassland, unique to the north-western fringe of Europe. It is listed on Annex 1 of the EU Habitats Directive, and occurs over a total global area of just 19,000 ha, with 70% of this in western Scotland, mostly on the offshore islands, and the remainder in western Ireland. These habitats support internationally important populations of many wading and farmland bird species, notably the Corncrake Crex crex. They also protect a number of important plant species and a variety of other wildlife, including the rarest UK bumblebee, the Great Yellow Bumblebee Bombus distinguendus.

The unmanned RSPB visitor information centre explains the importance of traditional crofting agriculture for rare birds and other important wildlife. A few images from my recent visit above.

Stinky Bay …

Iceland Gull (Larus glaucoides)




Despite its vernacular name, the Iceland Gull does not breed in Iceland but in Arctic Canada and Greenland. In Britain, it occurs mainly in the north and west during winter. Numbers appearing in Britain fluctuate considerably and large influxes occasionally occur, possibly associated with severe northwesterly gales. L. glaucoides is a very scarce winter visitor and passage migrant in Sussex; around 89 individuals in total being recorded during the winter periods of 1961/62 to 2010/11. Prior to this only 26 had been recorded in the county. Most records relate to individual birds observed in late winter or spring. The above pictures of a second summer bird were all recently taken during very overcast conditions on Benbecula in the Outer Hebrides.

Bucket list ...

Eurasian Otter (Lutra lutra)


It’s taken me a very long time but I’ve finally managed to see and get a reasonable photograph of an Otter in the wild in the UK. The above male was recently spotted hunting for flatfish and crabs in a sea loch located on North Uist in the Outer Hebrides. As luck would have it, as the prevailing weather conditions really weren't very good, he decided to come out of the water and on to a small grassy bank to pause for a few moments before returning back to his watery domain.

All I can say is, "well happy" …

Looking beyond the obvious …

Ready to strike …

European Adder (Vipera berus)


The Adder Vipera berus is the only venomous snake in Britain. It is easily recognised by the dark zigzag stripe running down the length of the spine. There is also a row of dark spots along each side and a V or X shape on the back of the head. It has red eyes and is the only native reptile with a vertically split pupil. Background colours vary from grey-white in the male to various shades of brown or copper in the female. On occasion, completely black specimens are described. Males grow to around 60cm in length and the females to around 75cm. Both sexes tend to have a rather stocky appearance.

V. berus is found throughout Britain right up to the north of Scotland. In Scandinavia its range extends into the Arctic Circle. It is not, however, found in Ireland. It likes open habitats such as heathland, moorland, open woodland and sea cliffs, and rarely strays into gardens.

The best time to see V. berus is during early spring when they emerge from their hibernation sites. By mid April, the males have shed their dull winter skin and are ready to mate. On warm humid days there is a lot of frenzied behaviour, with males looking for females and occasionally dueling with other males for territorial supremacy. The males writhe around each other in an impressive way, often covering the ground at great speed. It is an impressive site if you are fortunate to witness it.

Peziza ...

Anything but straightforward …








During a recent search of old parkland in West Sussex I found a small colony of the above cup fungi, which I believed to be a Peziza species. They were growing amongst a chipped softwood mulch at the base of a large cedar tree.

Cup fungi, the brown ones in particular, are especially difficult to identify with certainty. Having photographed a representative selection of the specimens, I collected several samples and later passed them to Nick Aplin, the county recorder for ascomycetes, for his opinion. Nick has tentatively identified them as Peziza varia s.l. Species delimitation in this group is quite controversial and there are several undescribed species, which could be a good fit as the spores from my collection were just a bit large for P. varia. The samples have been dried with view to DNA barcoding and further study later in the year. My thanks to Nick for his time and opinion and for the above photomicrograph.

Aroma-dentity ...

Fragrant Funnel (Clitocybe fragrans)




Widespread and common throughout much of Britain, C. fragrans can be found in both deciduous and coniferous woodland, often amongst mosses and grasses, and also on woodchip mulch in gardens. Although superficially resembling many other ‘brown’ fungi it has a sickly-sweet anise scent [along with a number of other species], which forms an element of the characteristics of this species. The above specimen was recently photographed in a mature conifer plantation in West Sussex.

My thanks to Nick Aplin of the Sussex Fungus Group who kindly confirmed the identification.

Your challenge is to find them somewhere else …

Spring Hazelcup (Encoelia furfuracea)






Having eagerly jumped at Clare’s proposition, “Your challenge is to find them somewhere else now”, I then stopped and really thought about it in more detail. Just how hard was this going to be? Did I stand any chance? Well, as luck would have it, fortunately not too hard as after looking at more Common Hazel Corylus avellana than I care to remember and, fortunately just a short drive down the road from where I live, I managed to find four small groups in private woodland on the outskirts of Kirdford, West Sussex.

As with many things in life, once you know what you are looking for e.g. its size, shape, colour, habitat, season, etc., things start to get a little bit easier. However, although widespread, E. furfuracea is generally regarded as an uncommon find in Britain. This irregularly shaped cup fungus can be found during the winter and spring. Typically clustered in small groups on the dead wood of C. avellana it has occasionally been recorded on Common Alder Alnus glutinosa.

My thanks to Clare, Jim and Dawn for their guidance in the first instance …

A welly full of water …

Bog Beacon (Mitrula paludosa)





Early spring and summer is the time to look for M. paludosa. This saprotrophic [feeding on dead organic matter] earthtongue is usually found on the remains of higher plants, mosses and algae in areas of seeping or standing water including streams, ditches and pond margins. Although widespread in Britain it can be difficult to find and is generally uncommon. Despite its bright yellow-orange head and its gregarious behaviour, it is easily overlooked. You will not find M. paludosa where the habitat is unsuitable, but neither should you assume that where the habitat is suitably boggy with plenty of decomposing vegetation it will appear - more often than not it doesn't.

Be careful of the depth of the water though …
