Black freckles on Dendrobium.

[Linton]

About a month or two ago, I bought a phal type Dendrobium at Ikea with what I think is some black scarring on some of the leaves. The plant was in bone dry sphagnum for several weeks but I kept going back and looking at it and eventually just had to rescue it, despite not being sure what the black spots were from.

When I got home and repotted, it turned out to be two separate plants growing in little coconut husk blocks, wrapped tightly in the sphagnum. The plant on the left seems to be in fine shape besides some older dehydrated canes, but one of the smaller canes on the other plant has been developing small black freckles in addition to the larger black spot that I thought was just scarring of an abused plant.










Is this a virus or infection of some sort, or is it related to the dehydration the plant went through? Should I cut off the smaller freckled leaf?


On the bright side, I have a cute new growth.


I'm still new to orchids, so thank you in advance for your help.
