Any idea what this is

[Marty.H]

Spotted it growing on part of one my Forest Fires so better to be safe then sorry I broke it off and binned it but would really like to know what it is the things growing out and the red blotches.

Ignore the green algae that's cheato from where I filled bowl up from sump

Any ideas
