My Rowan & Ceanothus have dark brown formations on their branches that crumble if I touch them. Some Clover flowers in the re-wilded "lawn" are also dark brown. Could they all be affected by the same fungus? Possibly Cytospora Canker?

    Clover flowers turn brown when they're finished, so are you sure it isn't just that?
     
    Would need a photo of the others. Are you in the UK though?

    I live in west central Scotland - not where that photo is...

    There were about 25 branches like this on an otherwise healthy 5 year old Rowan tree. At first I thought it was suffering from lack of water as they appeared just after the last hot spell but most of the branches were perfectly fine. Then I started cutting off the dead twigs & the brown formations crumbled in my fingers, so I've burnt the twigs in case it is a fungus.

    More photos would help for ID - of the ceanothus and the rowan, preferably, showing the whole plants as well as some close-ups.  It's not really possible to say what's caused the problem without seeing a bit more...
    Since 2019 I've lived in east Clare, in the west of Ireland.

    That was the Ceanothus. It often flowers twice a year. I don't remember the dead flowers looking so dark brown before. Is this a problem or just dried up flowers? I think they usually go a pale grey colour when dried up.

    Didn't think to photograph the Rowan before removing the dead branches, a couple of days ago! Some of the branches are quite bear where the branches were removed.
    The next pic of the Ceanothus has lots of brown clusters but they don't show up very well.

    I can't see anything wrong with the rowan. In the earlier pic, it looks like old berries that haven't been eaten by birds, but  just haven't dropped off. There seems to be a lot of stuff round the base of it though, which can be competition for water.

    The bits on the Ceanothus just look like the spent flowers. They've probably been turning to seed but haven't dropped off.
