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.

Common maybe ...

Tawny Grisette (Amanita fulva)



But I do like a nice Amanita fulva emerging from its 'egg' ...

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.

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.

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 …

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 …
