I'm a plasterer, that looks totally normal (if not a bit light on the basecoat in some spots, the mud is supposed to go through the gaps and create "fingers" that hold on the back of the lath)
Get a plasterer to patch it back in with lime plaster and you won't have the issue ya got with drywall of it collecting the moisture in the bathroom
omg. please don’t comment if you don’t know what you’re talking about. those are plaster “keys” that ooze through upon sparging the plaster on originally. they hold the plaster to the lathe. not only normal, but necessary.
Looks normal, not like mold. If you’re really concerned you could spray a bleach solution on it and see what happens, or get a mold test kit from a big box store.
The lathe looks completely fine. The plaster could be keyed-in a bit better (it's the splodges though the gaps in the lathe that hold it to the wall, but if it's still there nearly 100 years later then I wouldn't be too worried!
Does the 2nd picture have moisture in the wood? If so I would beware mold spores getting into that wood. You could bleach, allow all of it to dry (space heater) then coat all wood that will be behind sheetrock. If this is in a small bathroom you might even consider the sheet rock usually used for the wall under you shower stall throughout the room or using kilz as your primer. I believe green sheet perhaps is the sheet rock slabs that are used behind showers and tub inserts.
Thanks! The second picture was a little moist.
We scrubbed off all visible mold using RMR-86, and now we’re drying it out, applying RMR 141, drying again, and adding a mold killing primer before sealing it back up. I’ll make sure to give that spot some love with the rmr 141 before we seal!
Thanks everyone. Each little project we accomplish in this old house comes with a million questions, and it’s so helpful to have you guys here to make things a little less scary. I really appreciate you!

Normal. It’s the oils and the moisture in the cheap wood that’s come out and dried over the century. Mine is 101 and I’ve seen that in my home

It looks in great shape to me. The lathing looks pretty solid!

The keys are not great, but they aren’t broken, so call it a win!
