the last ones a bank holiday, youll want that with family? make it one before or one after first one in september? you set the date im free:thumbup1:

lovely examples

avoid the canter like the plague

yes I was trying to remember who it was, im sure they are tuned in, if not i can look back, the time is approaching now. Im tied next weekend but its still a little early anyways, how you fixed over the last weekend or around that time of august? If were making a day of it, Epping is not a massive drive from Hatfield, could do both in a day for the headstrong uba keen ones!

All angiosperms produce phenolic compounds, as opposed to gymnosperms producing terpenes, and resins of course. These substances are released by tyloses when the cell cavitates/aerates through failures or old age, dysfunction of vessels. The phenols or terpenes become a boundary to SOME fungi, for example those not possessing the enzymes needed to break down the particular substance involved. For instance, tanninase in Fistulina hepatica, as it is a tannin specialist. Or like the P. schweinitzii which passes the tyloses in larch very easily, having no really high resin levels, but struggles to penetrate the more resinous pines, like Pinus sylvestris in which Phaeolus is considerably slower and inherantly more managable, a longer term prognosis, unlike the larch which it runs rampant in. much like the Laetiporus does in willow and beech, versus oak and Castanea. deletions have to be MUCH quicker when i am around!

youll know it when you smell it, like riding a bike me old mucka, you wanna go for a foray with me this autumn?

I can assure you I pick only what nature can spare, there was 200 plus fruiting bodies present, and this is a common fungi:thumbup1: and who else is going to educate you lot!

your beech has suffered from drought stress and evidence of possible cracks, and bacterial slime flux long since dried to a grey. root damage and drought induced, white fluff cryptococcus fagisuga also a sign of stress. All common problems on an aging or stressed beech, one thing leads to another, but strips of cambium dying after drought and subsequent strip cankers due to the aeration of wood.

yes, as have I, some make it easy, like the edulis and impolitus (which has a stipe that smells of iodine, the edulis has a very characteristic reticulation. The biggest problem ive found is getting to grips with terminology of taxonomy, the language of mycology. Im getting there now though, and long overdue I put in the time and effort.

Indeed, very well put. One of the key things in the admission for membership to the BMS is a set of codes you agree to, one of those is that as a member "you will at every opportunity promote and encourage the education and publicising of the kingdom of fungi" or words to that effect, have taken that very seriously for some time. The fact that the few top mycologists ( around 8 taxonomists in the U.k) around were reaching "an age" with few coming up through the ranks was of great concern to the society. I have since discovering fungi been stunned at the sheer lack of education, and information available on the subject, though it is becoming exponentially better. One only has to look around now to see just how widely loved and appreciated the fungi are now, folk seem fascinated when presented with the subject now, lets hope in another decade they are not feared anylonger. Its becoming very cool o be a mycologist!

Very nice image sean, wouldnt be a fell in my opinion, i just dont manage hispidus on ash that way. very nice ripple formation in the dysfunctional pathway there sean, did you note it originally? Heres a few low ones, last in cahoots with perenniporia fraxinea, low brackets not at all unusual in my experience

Robinia is a choice wood for schnapps barrels too, nice timber

This is a Pluerotus, maybe P. ostreatus, but also possibly the cultivated more metalic grey/blue genotype:001_cool: Lets not get too into the knitty gritty of this but lets not use the "defence" word, trees dont really defend against saprophytic fungi, what they do do is prevent further dysfunction by sealing aerated areas. This is what Tyloses do, restrict further cavitations in the vessels in the vertical direction. The barrier zone or wall 4 (Sharon) is the only really effective barrier and is only really put in place when large scale aeration via massive limb failures etc have occurred, but even so some fungi can use this barrier as a food source. that tells us trees CANT defend against fungi, there is NO substance on earth, including radioactive isotopes that are resistant to fungi of one form or another. no substance either natural or man made. I was under the impression you was in need of enlightenment, but of a different kind:wink: I am teasing Jonny, long time no see, hows things with you? have you got your happy pills yet? Based on the texture in the image, but the later images here suggest you are correct, but I would like to see an image of this other one at a later date, just looks far less uniform than I would expect for a forming bracket of resinaceum. It has the fine ripples in the texture, which resinaceum does not from what I can see. You know how hard it can be from a single image. Your fungi Is Ganoderma I suspect australe oak copes very well with it if growing conditions are optimal, creates large cavities and much buckling at late stages as with planes.

Boletus luridus, Bay brown cap, reticulations on stem separating it from the olive green to brown capped B. luridiformis without reticulations and B. satanas with reticulations but a pale cap. Bruises black, turns blue on cutting, no distinctive smell. Mycorrhizal:001_cool: (Reticulations are a net like feature on the stipe)

Did dinner for my mates sunday, bar the chicken all came straight out the yard, went down a bomb, yummy yummy in my tummy.

Lmao, Might be an idea as it goes!

true, it takes a fair amount of wood to produce a fruit body, Lynne Boddy says that fruit bodies contain high amounts of Nitrogen (pers comm) and gerrit stated a fruitbody is about 20% of the weight of the wood consumed, though exactly what he said I couldnt quote. I would like to analyse the details scientifically as there is no specific work I can as yet identify to elaborate. Take mycorrhizea, they say that it requires around 80,000,000 mycorrhizal nodes or root tips to have enough energy to form a fruit body, so gives some indication of just how much mass/energy is required to be converted to solid fruitbody. The fact we are having this conversation at all is for me joyous, mycology was a silent subject talked of in dusty rooms not so many years ago:001_cool:

It is Laetiporus of course, nice example too. It is difficult to be 100% accurate on the subject of wether or not removal of fruiting body would enable more or encourage more degradation, the fungi would have to have invasive potential, and Laetiporus does not, it is a mere saprophyte of heart wood. meaning that it only has accsess to what parts are no longer fully functioning or fully hydrated, hydration being the limiting factor in fungal growth. So in THIS case, for laetiporus removal of the fruit body wouldn't achieve anything or cause any greater degradation, it can and will only fruit with the energy of the resources it already has available to it, which in this case is most of the woody cylinder, willow not having any heartwood as such nore defining boundary of phenolic substances. Like on Beech, its a difficult management proposition at this late stage, with a willow somewhat easier as as long as it is not a drought season and well hydrated heavy reductions are very much viable. as will be the case with this one or let nature do its thing and self pollarding will be the order of the day here. i actually manage a very similar willow in a HIGH target zone, it hasnt bit me in the rear as yet some 6 years and two cycles into it and still some several ton above the decayed region which is at or around 80% decayed, heavily pollarded that is well within T/r limits. But I have to say of all the decayed trees I manage this one is the most difficult and concerning. more so even than a beech with meripilus IMO

I think youll be re identifying that as perenni later, or rigi:biggrin:

argh but you said because of the Ident, and NO I wouldn't, there would have to be small leaves, yellowing foliage, or interveinal chlorosis for example, die back before I concerned myself with soil conditions. If a tree has a fungi, like I. dryadeus, does that justify major soil works? Does I.dryadeus equal poor conditions and ill health? Or is it just a recycling heart rotter, that is part and parcel of the Oak as an Eco system in its own right, which just happens to be capable of causing 1 or two in a thousand to fail in difficult circumstances?

I wouldnt say soil work was needed because of Ident, whats your thinking? If airspade to evaluate, OTT in my opinion, when it is more than possible to evaluate the situation externally, at worst using a rod, as in VTA basics. When the tensile triangle is elevated above soil level ( as in Matthecks thinking tools) we can safely assume the root form is in its later stages, and hence the elevation to above soil tensile triangles as opposed to below, due to the undermining effect of the fungi in this instance. A very predictable pattern of decay Inonotus dryadeus (on Q robur/petrea and other heart wood forming trees)

wasps are insect predators, makes more sense than you think, they are very quick to switch on to communities of insects and the whole hive gets in on the act. as for my time, no worries, thats what im there for:thumbup1:

you there sat pat?
