Hey folks,
I received a division of Cym. erythrostylum today from a grower in Victoria (Australia).
As i took it out of its box i noticed some browning and black almost "scorch" marks on one pseudobulb, as well browning and blackenening of leaf tips.
Now as I don't have any test kits to hand at present (didn't realise I'd run out) that I can use to test for CymMV, the leaf in the 5th image sent alarm bells ringing, but I wanted another set (or more) of eyes to have a look over it first.
It has been cold here and in Victoria (with temps down to -1) so I'm also wondering ifs its had cold damage leading to fungal infection, which is causing the discolouration and blotching?

Additionally, the first 2 images are from the newest & youngest foliage, which don't show much apart from cold damage and possible bacterial infection (1st image) and puncture damage (2nd image)
What do you folks think?

Maybe it’s just the photo, but that looks very “directional”, which suggests an environmental factor, rather than a pest or pathogen.
