What's this in my loft?

Hi,

Went in loft today & found this growing/there.

Is this some form of wasps nest or fungi bloom?

All help appreciated!

Looks like dry rot, which could be costly to erradicate. Can you upload more pictures?

The hexagonal cells in the middle make me think it some form of nest being built

Corrected pic!
