Hello! I just recently purchased a new Cattleya from the brand Better-Gro (Can be bought at home depot or lowes)

After having her for a couple of days I noticed this little elongated black mark showing up on the sheath. It is on the sheath, but nowhere else on the orchid. I am aware that the purple flecking is normal for this cattleya, it is just the dark spot that concerns me.

I suspect some sort of rot or fungus possibly, but cannot be sure since I am reletively new to this hobby. When you touch the spot it seems to be indented as well.

What is this and how should go about handling it?

SIDE NOTE: I do not mist my orchids, so I really don't suspect it is from sitting water.

I think its just a dent.

I agree. Looks more like a bruise, mechanical damage.

Hi ancientmachine !
Welcome to our little slice of Paradise Group hug
Those Better-Gro plants go through a few flaming hoops
on their way from the greenhouse, to the Lowe's or HomeDepot garden center.
( I used to work at a Lowe's garden center so I've seen the drama in person)
It's totally normal for bumps and bruises to show up a day or two after getting
them home. Come check out some of our other threads on this forum, especially
the ' what's in bloom' one for each month...We'll look for your flowers there!

Thanks for all the responses. It actually ended up being black rot... spread within 30 minutes. I was going to try to save it but Ive decided to return it.
Uploaded a pic for you guys to see. It was not a pleasant experience, lol.
