Sycamore leaves found on the ground

Observed: 2nd November 2012 By: VeteranoakVeteranoak’s reputation in Fungi and Lichens

The green patches on the Sycamore leaves are reminiscent of the effect of cytokins. I wonder if they could be due to a fungus.
I would be grateful for any suggestions as to their cause. It is possible that a fungus is damaging the leaves locally, delaying the natural senescence-induced chlorophyll loss. I have seen this elsewhere in previous years so it is not uncommon.


Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

The spots look about the same size as tar spot (Rhytisma acerinum) this normally makes the leaves go black with yellowing around the dark area
