Perreniporia fraxinea, de-mystified?

[Big 'Ammer]

Tony,

 

if you slice through one and its a reddish colour, then its rigidoporous?

If you slice through one and the pore layer (tubes) are a distinct colour band its rigidi.

 

perenni is even colour, same throughout flesh.

Rigidi, right?

[sean]

sean your image is indeed rigidiporus, P. fraxinea is evenly coloured hence the name "fraxinea" meaning it is like the wood in colour and tone, and that applies throughout its body/flesh.

 

Perenniporia is also most frequently a large flat profile as aposed to rigidiporus which tends to be a deeper profiled fruit body.

 

Any discolouration of the tube layer indicates rigidiporus, even colour perenniporia.

 

this image was a first for me, perenniporia on Oak. Q. petrea/sessile

cheers tony......think thats all pretty clear now.......one more thing.....are the young fruit bodies similar in appearance too and do the tubes still differ in colour at an early age?

yes same as, young or not, though in the first years growth thier will obviously be no old layer to compare to.

 

It may help also to say that rigidi in old age tends to be of similar appearence to a gibbosa bracket, bleached and white, even a little crumbly, whereas Perenni is hard, rock hard and and unlike the orange hues in youth or the white hues of age in Rigidi, perenni often has a pink lip in age almost magenta.

 

Any red/pink hues suspect perenni

 

orange to white hues, suspect rigidi

Tony,

 

the bracket in my picture is on an ash tree. Is that unusual?

NEVER rule out ANYTHING with fungi, NEVER!

 

No both rigidi and Perenni will colonise most broadleaves, yet to see it, but wont rule out conifers till certain.

 

As I said earlier found it on Oak this week, Rigidi seems to be hungry for Horse chestnut and poplar, whereas perenni loves ash, beech and oak, maybe hinting at a preference for harder woods?

In your shot there is a darker old tube layer that threw me a bit, ive not cut many bodies because I dont like to, and having had a bit more experience with this pair I would suggest your one is Perenniporia, its very common on ash, which rigidiporus is not IME.

 

whats made my mind up? well the new pore layer is the same as the flesh, its only that old tube layer thats darker. But yours is also very thin in profile, so knowing what I know now, I would be 99% certain youve got a Perenniporia fraxinea.
