Breutelia chrysocoma, also known as the bottle brush moss[1] and the golden-head moss,[2] is a species of moss in the Bartramiaceae family.

It is an attractive and conspicuous moss found most commonly in the north Atlantic, with strongholds in western Britain, Ireland and western Norway.

[2] Other populations have been found across western and central Europe but far less common compared to the hyper-oceanic zone of northwest Europe.

It is most commonly found on upland acidic grassland, especially near flushes.
