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 …

Wet woodland on a winter’s day …

Scarlet Elfcup (Sarcoscypha austriaca)





The stunning S. austriaca, commonly referred to as Scarlet Elfcup, is widespread but generally only occasional throughout Britain and Ireland. It appears in winter and early spring on dead hardwood twigs in damp, shady places, usually partly buried amongst moss and leaf litter. The fruiting body is cup-shaped with a smooth scarlet interior. Of course identification is never as easy as it may first seem as the macroscopically almost identical S. coccinea, the Ruby Elfcup, occurs in similar environments. The two can only reliably be identified by DNA analysis or, to those of us without such facilities being readily available, microscopic examination of the tomentum [microscopic hairs on the outer surface of the cups] and spores.

The above images show a small selection of specimens recently photographed in West Sussex. My special thanks to Nick Aplin of the Sussex Fungus Group who kindly supplied the photomicrograph and confirmed their identification by observing the distinctive ascospore germination and the depressed spore poles which separate S. austriaca and S. coccinea.

Ecclesiastical fungi ...

Cedar Cup (Geopora sumneriana)








G. sumneriana is an unusual ascomycete fungus which is typically found partially buried in small groups beneath cedar trees in parks, gardens and churchyards. This relatively large cup fungus initially develops underground as a hairy orange-brown to reddish-brown sphere before breaking through the soil surface and opening up to form a crown-shaped cup. It is a widespread though generally uncommon find in Britain. The above examples, including two specimens growing through the cracks in a tarmac path, were taken recently in an ancient churchyard in West Sussex …

We can’t get any further without microscopy …

I’ve heard that one before …



Back in October 2016, when I seemed to have a bit more time on my hands, I spent a number of days hunting for fungal delights in the rich and varied woodlands of Ebernoe Common in West Sussex. Over 1000 species have been recorded here including many that are nationally rare.

With a passion for the smaller things in life, on Monday, 31st October I photographed the above species. The off-white fruiting bodies of this tiny ascomycete fungus, approximately 1 to 1.5mm across, were found on a rotting piece of timber, possibly English Yew Taxus baccata. Lachnum and Dasyscyphella are probably good guesses, but unfortunately I won’t get any further without a sample [which I didn’t take] and microscopy.

I’ll be taking sample pots next time …
