Hi Ste, my name is Wolfgang . I live in Germany. I work as a mycologist and building biologist. I am sure that the dark brown to black mycelia in your picture are not from Serpula lacrymans, but from Coniophora puteana! To be honest, it's a beautiful picture that you won't often find of Coniophora puteana in a building. Best regards, The Mycologist (talk) 15:38, 25 August 2024 (UTC)
