Red raspberries

The raspberries are gradually coming ripe now.  We've eaten a dozen, I think.  Each one is absolutely precious.  The thing is, it's been raining since early July (you think I'm exaggerating, don't you -- check the data: We've had rain 20 days in the last month) so ANY fruit is a bit of a miracle.  There are a few berries that are covered in a sort of grey dusty mould or fungus.  I KNOW that's not good.  I can't help but think that today's sunshine is too late to save our crop this year.
