Dry rot

Hi there

I am getting professionals to look at this but wondered if anyone could give me an indication in the meantime. Does this look like dry rot to you? Apologies for the poor quality photos, it's the best I can do with my phone camera.

Note the fine cobweb-like strands and some discolouration of the timber. On the positive side I haven't identified any brittle wood and there is no smell.

Thanks a lot

Should have said this is in the subfloor of a house I just moved into with inadequate subfloor ventilation
Looks fine to me. Looks like the fine cobwebby strands are cobwebs.....

Yep. I'm with the others. This is what galloping dry rot looks like:



OK, advanced examples, but I'm sure you get the drift
Thanks for the reassurance all. Surveyor's report highlighting high levels of damp and consequent high risk of rot got me paranoid. Will be doing works to eliminate the damp and fully rule out rot in any event, but will rest a bit easier in the meantime.
The best prevention is good airflow
Unfortunately the previous owner blocked off the airflow with a concrete floor on an extension.

Damp surveyor who looked at it pre purchase said the layout means simply reinstating an air brick won't work and recommended filling the subfloor with concrete. I am keen to do in a less extreme way - maybe by installing a fan in the subfloor.
