Perhaps Rhodococcus fascians which causes similar effects in broad leaf plants?

This looks like a version of fasciation, no? Caused hypothetically by the interplay of temperature, light and nutrition; the problem is always to repeat the interplay in a lab. And no one says there's only one formula. ... I send this flippant response because I have encountered fasciation several times in my garden lilies; they all returned to their traditional form a year later; and when I tried to recreate fasciation by simple manipulations, I failed. Fasciation is complex but it does appear that your lilies are in its temporary grip.
