Laetiporus sulphureus ---- Chicken of the Woods -- on Pine

Tony posted this species on 23rd June which had been found on a Yew and this find from woods near Trimsaran was on a Pine.  Sulphur Shelf, another common name for Laetiporus sulphureus, is generally found on broadleaf trees, most commonly Oak so it is surprising that these two recent finds were on 'conifer' (Yew being a type of conifer, I think).

Tuesday at the N.B.G.W. around the outside of the Great Glasshouse - these Blackening Waxcaps were spotted and identified by Jan Crowden. There must have been a dozen in various states of 'Nigrescence'- the old name seems to be more descriptive I think.

Laetiporus sulphureus

Chicken of the Woods

Colin Miles of the Conservation Vols. sent me this picture of a Bracket fungus he found growing on a Yew tree in Llannon this morning.
When he described it as "a magnificent specimen" he wasn't exaggerating.
It is almost certainly Chicken of the Woods which is often found on Yews.
Unlike Ian's Hen of the Woods (which is a white rot fungus) this species is a brown rot fungus, although the eventual outcome for the host tree is likely to be the same for both species.

A gall on Camellia

Not a fungus - sorry - but a gall, Exobasidium camellinae, found on Camellia in Stradey Woods, Llanelli by one of the estate staff, Vince Somers-Yeates, who kindly forwarded me the photo below. I also recall Dr Philip Jones reporting a sighting from Laugharne back in 2006.

Bolbitius reticulatus

Netted Fieldcap

I came across these walking through the wood last week.They were growing on a piece of fallen branch which was probably Oak.
Pink gills and growing on wood usually means only one thing, they are one of the Pluteus.
There around 20 different Spp of Pluteus and they are not always the easiest group to key out.
However when I started to investigate further I discovered that they had Brown (not pink) spores, so could not be a Pluteus Sp after all.
Looking through the literature got me nowhere, and only an inspired piece of detective work by Philip came up with the answer. 

The common name is less than helpful, they have neither a netted cap, nor are they found in a field!
In fact some of the information in one well known field guide told me they are an Autumn species found on calcareous sites (my wood is acidic)!!!!!

Still, got there in the end (mainly thanks to Philip).

There are only a couple of Welsh records for the species, so another nice find and another first for the wood.

Hygrocybe conica

Blackening Waxcap

Walking round the National Botanic Gardens today, Peter Williams spotted one of these in the grass close to the Great Glasshouse. 
When we looked further there was a whole troop of fb's in varying stages of blackening.
Looking at the older specimens it was easy to see how they got their other common name which is the Witches Hat.

PS The species used to be known as Hygrocybe nigrescens -  yet another name change to learn!

Suillus grevillei

Larch bolete

While walking in a larch plantation along the river Gwenlais near Cilycwm I spotted these slippery characters. Most had been eaten badly by snails or slugs so I was happy to find these nice specimens.
