it can be pretty disconcerting when you listen to Merip decayed roots on beech, we've come across some examples where the upper section of the roots are hard and relatively vascular but sound like a clay land drain when tapped. .
-
I'm sure Andrew won't mind me using this, as he posted it on previous threads many moons ago. Based on his observations, he illustrates how roots (oak in this case) can morph over many decades in coexistance with Grifola frondosa which is a similar association (but potentially less aggresive than...) Meripilus & beech. .
-
If I'm honest Julian, I don't recall reading anything specifically relating to why (but, I'd guess it will have been covered in a number of the usual suspects) I'd imagine that it will probably be a combination of biomechanics & physiology. .
-
Tree roots don't grow like branch wood. As they age they lay down new wood at the sides and top and less and less at the bottom. Eventually this wood is dysfunctional and fair game for the mycelium of Merripilus giganteus. Andrew Cowan produced a great diagram of this process of root morphology. I'll try and dig it out. .
-
Pleurotus sp perhaps P. dryinus is fruiting a lot in beech cavitities down here currently .
-
Pretty desiccated, but I would imagine either Meripilus giganteus or Grifola frondosa. .
-
not so much a case of 'developing fruit bodies' more a case of 'developing son' same tree five years apart bless the wee man, he never grumbles .
-
just thinking out loud here, so I'm not saying that this is the definitive cause... perhaps its a lack or reduced presence of lignin between the primary & secondary cell wall (made up of cellulose & hemi-cellulose), which may affect & make the wood volume partially collapse particularly in compression. Bit like being spongy and not rigid (which is the property lignin gives wood particularly in compression situations. Might be interesting to know if the ripples were from the under side of a leaning trunk/underneath branches or from the entire circumference of the wood. The below example is a woodland beech.... .

Absolutely ! really have no idea about these odd growths on trees All good thanks Paul .

a great wee ash pollard in Norfolk...... .

On Sorbus? If so, my guess would be Inonotus hispidus .

Foraging (for fungi) becoming an issue ?
David Humphries replied to David Humphries's topic in Ecology
I don't agree with your analogy here due to the nature of the ecology of the species being 'poached' Pheasants are a 'naturalised' species that are managed to be shot and abundant in number (granted poaching them is obviously illegal) There are certain species of fungi that are incredibly rare (in part due to their specific habitat) and protected by law (because of their rarity) which are probably picked without a single thought to the fragile nature of their continued existence and let alone the hazard of their toxicity. The 'art' & knowledge of sustainable foraging is being diluted by commercialism . -
A colleague has recently been interviewed about the issue of 'over' foraging by gangs who are stripping ancient woodland for commercial purposes. Illegal foragers are stripping UK forests of fungi | Environment | theguardian.com Not something I've seen occurring within the woodland where I work But certainly noticing a dearth of fruit bodies where as many other people across the mycology forums are seeing a wide variety of species all across the UK. So perhaps in the early hours there's picking going on unseen. Any views? .
-
Pretty simple really, I don't have confidence in saying its Armillaria tabescens or Pholiota squarrosa. I offered squarrosa simply to suggest there might be more than one option. The spore colour is the key. .
-
I don't see anything that would commit me to either offerings, sorry .
-
Yes, the other Armillaria species in the UK (five I think) have an annulus (ring) Honey Fungus - Friend or Foe? .
-
Armillaria tabescens - The Ringless Honey Fungus - David Humphries’s Fungi Directory - Arbtalk.co.uk | Discussion Forum for Arborists .
-
Yes I understand your negativity toward the 'possibility' of these being the scaly cap, but your offerings are desiccated and quite easily may have had their squamules washed off by the rain. The lack of ring may be the main puzzler here, but again without looking at a wide number of them in the flesh then an ID will always be difficult. The clincher will be the spore colour. If it was whitish then probably Armillaria Sp, but if brown then probably Pholiota sp .
-
host would suggest Pholiota squarrosa as a possible .
-
Yes, Phaeolus Nice example .
-
The issue with standing dead wood is frequency of inspection and further management if required. often poor species choice and host fungi are left and then fail at some future point without being inspected at appropriate intervals. (Been guilty of this myself) .
-
A nod to the local ecology via a low monolith would have been nice to have seen. Hey ho Thanks for updating Gavin .

I'm a fungi, I'm a fungi, what fungi am I?

Good call Kev Scleroderma citrinum absolutely tripping up on them in the woods yesterday .

Really likeable guy, glad he's not on my gang though it was painful to watch in parts. Hope he's never been seriously hurt. Thanks for sharing Tim. .
