Is this fungus growing out my brush?

Just noticed this strange looking stuff oozing from my brush head. Any idea what it is ot what type it is?

 

It's a type of cup fungus, what you see is the fruiting body rain drops land in the cup and the spores get bounced out.
There are many species of cup fungus; I generally see them on old dead wood.
Might be time to get a new brush and retire that one.

 

There seems to be a fungus for every occasion.

 

When I saw the title of this thread I thought it was about Thrush.

 

This brush lives outside as I'm constantly brushing leaves off my lawn. It still performs admirably! Will the fungus compromise the structure of the brush head or does the fact the fungus is there mean it is already rotten?

 

It says brush, not bush! Typical filthy Edinburgh man

 

It means the wooden bit is in the process of being devoured.
The bristles might still be OK.

 

You might soak it in Jeyes fluid, drain and then store it in a warm, dry place. You might cut two pieces of 20mm board and screw to the back, once dry, to reinforce. You could buy a new head, to attach to existing handle.

 

That's an intriguing solution. However it really is a sacrificial tool I keep outside for easy access and the handle is metal and showing signs of rust but thanks!

 

Looks like that brush head as had it. The fungus will rot and weaken the head in time. Leaving it outside in all weathers has no doubt sped up the process.

You could do what Trigger did with his council brushes from "Only fools and horses". Change the heads/handles as they wear, and yet proudly maintain to friends and family that you've had the same brush for years! Lol.
