Very small brown swellings (galls?) on the underside of a Spanish or hybrid bluebell leaf.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
bulbs suffer with several viruses, also eelworms which can distort& streak foliage & flower stems
Thanks for the suggestion re. the rust. I have followed it up and duly edited the title of the observation.
