Inonotus dryadeus


Recommended Posts

Given the reputation this lovely and most photogenic of fungi has gotten I thought this subject was long overdue a discussion, I have very little to agree about, probably no suprise:laugh1: with much of what is said. I so far reckon im working on a 1 in 1000 chance of failure going on the fact I must have witnessed 1000 colonisations and only 1 failure:001_cool:

Grazing/mower/construction damage on the upper root surfaces is one situation where I would be concerned, but healthy vital trees with no crown symptoms and no scaring or damage complications I would not be so concernernd about.

 

Inonotus dryadeus is generally a recycling fungi, living off old tissues in the core of the ageing tree, there is one tree at bradgate deer park which has entirely coned out and now lives on stilts (adaptation and new roots) this is not an isolated form I have heard others call it the "Eiffel tower form"

 

Obviously as with all decay organisms, the presence of fruit bodies and in proximity of targets one MUST make a detailed assessment of the decay, each situation and circumstance is unique, no two patients are the same.

 

before I go into my views on this fungus i thought i would offer a few visual illustrations of the fungus in its many guises and forms, with the intention that these images will allow you to make your own minds up about this IMO over estimated fungus.

 

Part of the tree species specific ecosystem wouldnt you say Gerrit?:001_cool:

Part of the tree species specific ecosystem ?

 

Tony,

Great and valuable documentation :thumbup: .

Sure it is, though I'm not the best judge of that, as the species in The Netherlands is very rare, obviously because we have so few veterans oaks (left), and because according to Weber & Mattheck, in Germany it mainly fruits on urban trees without well-developed tree species specific ecosystems, but that's maybe why the oaks are so easily colonized.

The very first image in this thread i saw yesterday, and commented to Charlie that I would have loved for you to see it, it was a very handsome and impressive example and tree, i love the root wraps round the old tap root.

 

I will be looking to the Euro map to see if my suspicion on this being limited to warmer areas is right, I.e more common in southern regions.

 

Im starting to see that inonotus dryadeus and Fistulina hepatica "Claim" a tree as its territory and have very specific body languages hence the various forms of english Oaks. It will be difficult to do so, but I need to build a comprehensive understanding of the other two oak species specific fungi, Piptoporus quercinus and Phelinus robustus. I think that because the latter two are confined to very old oaks almost exclusively within ancient deer parks (King Oaks) that they are possibly dependent on certain pre existing conditions within the tree species specific frameworks. One thing I have come to see more often is Honey bees in some of these old oaks, often with Piptoporus, just a hunch at the moment. Knowing how Piptoporus copes in interactions with other fungi in the oak species specific eco system would be a big step in the right direction.

 

Ever since you brought that concept to my understanding I have had a lot of new questions at previous block points:thumbup1:

 

I am very very lucky to live in a land full of historic parks and rich in ancient woodlands, such fertile ground for a fungi enthusiast, and a great place to study ideas.:001_cool:

In The Netherlands, of findings of P. quercinus is no documention, so it may - because of the lack of veteran oaks - not even be present at all.

P. robustus on the other hand, is quite common on middle aged solitary or lane trees of Quercus robur and Q. rubra, and recently also is a biotrophic parasite of Robinia pseudacacia.

COMMON! I need a vacation!:lol:

Hama do you have any experience of I. dryadeus on robinia? Afriend showed me a photo which i initially identified it being dryadeus but am trying to find refernce to species other than oak. cheers

 

I am asuming it was basal to lower stem?

 

Ive only ever seen it on oak, but seen photos (reliable) of it on beech also, that was a surprise to me I can tell ya!

 

as for robinia, its possible but suspect it was more likely perenniporia fraxinea.

 

It might be worth checking out the FRDBI database for hosts of I. dryadeus, but take note of those that have vouchers or reliable data sources, im not happy to rely on it otherwise.

Ben,

The only reference to other tree species than oak you will find, is that I. dryadeus once has been collected from Abies in (former) Yugoslavia, once from Pyrus in Sweden and that it's common on Abies in western North America (Ryvarden & Gilbertson), so you probably have found I. hispidus on Robinia, which is not that exceptional.
