ANOTHER Fungi on Yew

[Fungus]

pore surface is not what i would expect of hetero, nor is the laquered surface which is matt on hetero and more lumpy to

 

Tony,

I've seen lots of Heteroporus annosus brackets looking exactly like these on several coniferous tree species, including yew, and even on beech and Euonymus europeus, so only the colour of the spores will be decisive in this case.

you knew what I meant, as for visual pore shot, hence why I said it is not heterobassidion annosum even on photo evidence:001_tt2: the pores are larger and more angular:001_smile:

 

H. annosum

it is not Heterobasidion annosum even on photo evidence: the pores are larger and more angular

 

Tony,

Did you ever see G. carnosum "in the flesh" and what literature do you use ? Breitenbach & Kränzlin : G. carnosum pores 3-4 per mm, H. annosum pores 3-4 (5) per mm ; Ryvarden & Gilbertson : G. carnosum pores 3-4 per mm, H. annosum pores 4-5 per mm, so how much larger are the pores of H. annosum then ?

You even have started me wondering whether the identification of Guy Watson's Ganoderma on yew was correct, as all the photo's of G. carnosum in books and on the internet show annual FB's with well developed, according to Ryvarden & Gilbertson and Breitenbach & Kränzlin, 5 to 10-25 cm long stipes, looking like an upright threatening cobra, just as G. lucidum mostly does.

Gerrit, im not doubting you at all, I have never seen carnosum, and really cant comment with any serious intent due to that. I am purely from a visual perspective, satisfied this is not H. annosum.

 

In all honesty, it looks like a Gano to me, I would have said resinaceum, till David suggested carnosum

Out of interest Gerrit, of the 54 records of G. carnosum here in the Uk since the 1920's, all are on Taxus except for 8 which have been described as on Pseudotsuga menziesii

Also from a visual perspective, the - non-stalked - FB's in the photo's look far to irregular or "wülstig" to be an annual Ganoderma, whether it is G. carnosum, G. lucidum or G. resinaceum and the pores look much more like the (irregular) pores of H. annosum, which are just as big or even a bit smaller then those of G. carnosum. So the only decisive characteristic left is the colour and - provided it is a Ganoderma species - the size of the spores.

Funny enough are all the reports on G. carnosum elswhere in Europe mostly on Abies and sometimes on Taxus, Larix, Picea, Pinus or Pseudotsuga and also on Betula, Carpinus, Fagus or Quercus and is G. lucidum also reported from Picea, which is the host in half of the cases found in Fennoscandia. So one starts wondering how many of the findings of (stalked) G. carnosum and G. lucidum are identified correctly.

well the spore print under is brown anyways, so that certainly rules out hetero
