Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

  • hen of woods or giant polypore
    Confidence: It might be this.

It looks more like Grifola

It looks more like Grifola frondosa to me but from just the one photo I would not be too sure.

thank you, anything to confirm what it maybe is a start for me as long as it won't lead to any major branches dropping off as I live underneath it

Might well be the Grifola

Might well be the Grifola frondosa but need more photos etc, could even be polyporus squamosus as you can't really see the underside too well to get a good idea of size of pores. this second suggestion is less likely as it has bigger pores than this one appears to have and is usually earier in the year but growing at this height on the tree and scales on cap might fit.

Thank you again for your replies, so Grifola Frondosa is known also as hen of the woods I think, so is this likely to make the branches drop off or not. Can't find anything that says it is a major problem. It is a beech tree that is about 1.2 metres away from our bungalow and about a third of the canopy is over our roof. It is about a 150 years old. Other than a few other holes like the one shown and another further up that the squirrel lives in their doesn't seem to be anything else wrong with it apart from the base of the tree has got white mildew. I cannot get closer pictures as this was done on full zoom the fungi is probably about 5 metres up

Not sure if Grifola Frondosa

Not sure if Grifola Frondosa causes any damage, I have only seen it growing on dead stumps so if it is this species then it might just be growing on that decaying wood that you can see. Would suggest that you keep an eye on the tree though as beech can decay quite quickly once they start (unlike oak which can hang around for hundreds of years hollowed out and actually supporting more wildlife than when they are a young tree). Difficult to give any advice because the tree may well live another hundred years with a bit of decay like this, older trees always end up with some decay, it does not automatically mean there is anything seriously wrong with them.

Thank you for your comments, I think I might get someone in to take a look, a lot of tree above my roof and I need to sleep easy cheers

What i have seen

As a teenager i lived in an area that had a spectacular plantation Beech on a hilltop with housing on the flanks.
In the late 1970s there was an overnight storm that snapped a perfectly healthy Beech tree about 5M above the ground. The entire canopy was shattered when it hit the ground. In February 1989 there was a big storm that peaked in the afternoon that felled about 70 percent of the plantation and caused one fatality. I do not remember ever seeing any trees with fungi on them. The plantation was about 100 years old. I would say that Beech should be planted to the northwest of hills away from buildings if it is intended that they should grow to maturity.
I have used the Add an observation to get the location of a stone with the date it was planted and there is close by a memorial to the 1989 fatality. Only the northwest corner survived to keep its mature trees.
Honey fungus can cause branch drop without warning even in still weather. A branch dropped from a Beech tree in the grounds of the school i attended in the early 1970s on a mill stone still spring morning and the bootlaces of the fungus could be seen where the "heel" of the fallen branch had broken away.
