H. annosum on pine?

[Kveldssanger]

Saw this on Brownsea Island. Thinking it's potentially young Heterobasidion, due to the flesh colour, pore layer, rigid structure, and the really strong smell of fungus. Images linked you can zoom in to. Cannot say for certain as I have never seen it before - in fact, I rarely see fungi on conifers down in Essex, as there aren't many conifers besides young and brutalised atlas cedars, lawsons, and leylandiis!

 

Cheers.

Unfortunately the images don't seem to be arranged well!

hmmm dont think its H annosum. Have to have a look tonight at my fungi book see if i can find anything.

I admit if it isn't that I don't know what else it could be, as I don't deal with too many pines around my way. I noted that the flesh's whiteness is comparable to Piptoporus betulinus. I don't think it's a Postia sp., as it's too large and / or not white enough on the outer surface.

 

Potentially Postia stiptica gone slightly tanned? Though the tubes aren't 6-10mm deep, as Jordan says in his book. The tubes are shallower than birch polypore.

Has to be ionontus dryadeus - dryads saddle. Very rarely occurs on conifers though.

 

Early decay is a localised selective delignification indicted by irregular yellowish stripes within a zone of dark water soaked wood. The yellow stripes gradually enlarge and become paler until the whole zone becomes soft filamentous mass with thick sheets of white mycelium. The decay starts at the inner root system and can extend into the stem base up to 2 meters above soil level and is confined only to central wood. Attack is more or less confined to the heartwood. Most advanced stages of wood is seriously weakened however retains some tensile strength for a long time in early stages. Wind throw may occur but little evidence to show it’s common. Very difficult to detect decay. If in high risk location decay extent should be found out and potential reduction. Attack on heartwood causes little influence to the trees vitality until advanced stages of decay affect uptake of water and nutrients.

It couldn't be that, but thanks for trying to help! The flesh colour of P. dryadeus is a rusty brown, and this was pure white / cream coloured. Only ever known it to occur on oak and, according to Watson & Green, also beech very rarely. Shame though, as it does look like that outwardly.

Might be worth considering Fomitopsis pinicola Chris

 

Before it develops its usual 'red band' it's pale in colour and often gutates.

 

Host is a good fit (as per its name)

I hadn't thought of that one as I didn't know it was found in the UK at all! I have read about it on the continent (Finland, for example). I'd say it is indeed a good fit. Thanks, David - once again!
