Next year I'm going to draw (with a maker pen) round some of the egg clusters on the back of the leaves on some of our sycamores and see if that area goes black come autumn.

 

I'm sure there is some correlation between the eggs and the spots.

 

Be interesting if there is.

The black spots are the fungal infection. Nothing to do with aphids.

I always thought that it was the honeydew (aphid poo) deposits that this fungi grew upon. :001_unsure:

A mycologist who works for Ipswich borough council told me a few years ago that it is believed that Rhystima actually developed on a man's brain and killed him,how true it is I can't verify, spores were believed to of been inhaled

Not buying that one then David? I must admit I was taken aback when told the information, the thing is this guy really know his onions, he told me it was in a recent journal, I can't find anything to back it up, he was adamant it was ''tar spot''

Not doubting Lee, imagine it may very well be an issue us arbs are open to more than perhaps we would be comfortable with.

 

Particularly those of our ranks that spend a worrying amount of time down at pore level during sporulation, just to get a context set of shots. :001_rolleyes:
