Dear Forum,
I'm a Danish hill billy settled in the Sierra Nevada mountains in Southern Spain. We live in a small wooden house, so when I noticed these outcrops on my newly erected wooden patio I thought it wisest to ask you honorable members for your opinion.
At a glance it looks like some kind of fungus, but a closeup reveals these shapes.
The timber is about a year old pressure treated (copper sulphate) on the beams, and varnished with a water based (insect and fungi repellent) wood treatment.
Any idea guys
