Identification Please:

Found on Hawthorn (Crataegus monogyna), initially thought it was a gall wasp of some kind. On further investigation, it looks like a fungus. Really stuck. Willaston Meadow.

Mike,

I think it could be the rust fungus Gymnosporangium clavariiforme which uses two hosts to complete it's life-cycle, juniper and hawthorn. The tufts in your photo are tubes that release fungal spores.

Yes, Tongues of Fire (Gymnosporangium clavariiforme) - often found on the underside of leaves of Hawthorn, there being a dark reddish brown mark showing on the top surface of the leaf - see here: https://www.naturespot.org.uk/species/tongues-fire
