This handsome so-and-so isn’t in the wood – it’s in the wood pile at home. It looks like a stray blob of insulation spray foam but I believe it to be a slime mould.
These organisms can live as single cells but aggregate to form multi-cellular reproductive structures.
They feed on bacteria, yeasts, and fungi, commonly on decomposing vegetation such as deciduous logs.
We’ll keep an eye on it to see if it moves around or produces spores via fruiting bodies.
There is a great BBC video of a yellow slime mould migrating and fruiting here:https://www.youtube.com/watch?v=GY_uMH8Xpy0
