The linked picture is posted on behalf of Spider who is currently outside
making the most of the clement weather.

A few years ago she transplanted into a pot a wind- or bird- sown Birch
seedling.
Now it needs to be moved, but on removing the pot a number of fungal
fruiting bodies were revealed.
The gills are light coloured and it has no particular smell.

Can anyone advise please whether this is harmful or not? Spider is always
cautious about honey fungus because we have had it in the garden before.

Well, it's definitely not THAT! I can't tell you what it is or
how it grows, but I generally advise not worrying. Even if
fungi grow on a plant, they are quite likely to be effectively
harmless or even beneficial. And many grow on other things in
the soil.
