Hepatica and mycoplasma

promised to show plants Hepatica, presumably infected by mycoplasma.
I don't state such diagnosis. This my suspicion caused by the characteristic signs - a green painting of lobes, very large cup, the smaller size of a flower and some depression of the plant (not on all plants it is watched).
Colleagues if someone met similar on Hepatica or others Ranunculaccae - I ask to share knowledge.
Unfortunately, by training I not the biologist, therefore to judge 100 % it is exact I can not.
Very much it would be desirable it will be defined is valid a mycoplasma, or these are mutations, or something another?
As an example here the photos of plants causing suspicions.
Help it be defined with the diagnosis for these Hepatica.

I'm afraid I know nothing whatsoever about mycoplasma in hepatica or any other plant but if I saw these plants in the wild I would just be thinking how attractive they are, and, in fact, really nice plants, especially with their rather furry calyces and plenty seed forming. Many plants have a green tinge in their petals in some forms so this wouldn't occur to me as something not good. I'm not sure even sure what mycoplasma is, so I'll Google it.

Lesley, thank you!
I think too, that is necessary to be watched.
Only - I wrote wrong - for plants an infection such microorganisms is named фитоплазмоз. Oakwood showed infected phytoplasma Galanthus.
Here the article is in Wikipedia -

I think they are rather attractive Natalia.
Lovely subtle shading.

Please Natalia let's see the leaves too - it is easier to judge then.

Natalia.Not easy to say if they are infected or not. Like Gunhild says i would prefer to see the whole plant. But they don't look so "monstrous" like for an example infected Trilliums can occurre. But it's good to have a good check up for them. To spread mycoplasma infected plants is easy in garden circles because people normally look at them as rare sports instead of what they really are....sick plants.... that sooner or later will spread more or less to all your plants....//Jonny

I have found Anemone nemorosa, which were infected with mycoplasma. On the blossom there were green stripes, completly different to your shown picts. I have seen only partiel greening. I`ll search the picts, for sure it could be help

If we look at some of the clones that are sold by Japanese nurseries, they do definitely look more odd than these and since nurseries with breeding programmes probably would notice any infections since they ultimately kill or maime the plants, I would think that these are naturally occuring mutations. We also have odd-looking clones of A. nemorosa here in Europe such as 'Green fingers' and 'Virescens'. These have been with us for a very long time so they are likely to be clean. This does not mean that I can guarantee that they are healthy but as long as they do not dwindle, I would not be worried.

This one indeed looks bad. Nothing like green fingers and that ilk. I assume it eventuelly died??

Probably the plant died. I`m not sure, I have found it 2009 in a wood near to Slovenia at 1400m nn.
In the meantime I haven`t got the time to visite the area twice.....
My aim was to show, that infection with mycoplasma don`t produce completly green flowers in Ranunculacea. The greening is partiel without a proper scheme.
So in my opinion the plants, shown by Natalia aren`t infected by mycoplasma. If I right if only the older flowers turn to be green ?

Gerhard, I am sorry for the late reply ...
On plants with a photo - young flowers are greenish and become blue or other colors during flowering.
