The corridor outside our office is currently infested in one corner with a strange yellow fungus that looks almost, but not quite, like mushrooms. The culprit seems to be a leaking radiator pipe which you can see on the right.
This has been going on for more than a year now, with a particularly dramatic upsurge in the last couple of weeks, since the maintenance people turned on the central heating for the winter.
Since they’ve not done anything about it, we’ve decided to take the piss a little bit.
I would have preferred an infestation of badgers myself, but one takes what one can get.
