Found in woodland on Dicranum moss. A white felty covering on the rachis of the moss. More translucent when wet but white when dry.
No interactions present.
I've seen this a few times before on Dicranum but can't help with an ID I'm afraid. I'd be interested to find out.

A bit of Googling: In 'British Mosses and Liverworts: An Introductory Work' by EV Watson, it states of Dicranum scoparium that "The stems are sometimes covered with a whitish or orange tomentum" (tomentum being "A layer of matted woolly down on the surface of a plant"). Could the same apply to D. majus?
As I understand it, the tomentum on Dicranum is usually ginger in colour, but it often gets infected with a fungus, and this is what you are seeing when it goes white. Ask a mycologist for more details!
It would be worth submitting the observation again in Fungi and lichens with the second picture first for ID of the fungus.
Please, as suggested by Refugee

I am requesting that you add the tag Bryophyte as this will act as a further aid by virtue of attracting more of those who specialise in mosses and liverworts. Thanks in advance,
