Lichen on Magnolia

A small amount of lichen will not harm your magnolia and indicates clean air. If the tree is covered in it just pick off by hand.

Thank you moongrower. I am told it is lichen but here is a photo

Sorry the photo didn't appear so I'm probably doing something wrong.

Photo is there Casso and yes it is lichen.

Thank you moongrower. I thought it was fungus and have been spraying it witha fungicide.

Ah well that wont have any effect on it at all.

Thank you for the advice Moon grower. I'll leave it there now I know it won't do any harm.
