Identification: What beards ?

I know they are beards, but don't know which.
Difficult even with a book in front !

 

These are members of the genus Usnea, possibly all the same species, especially if you found them in proximate locations or similar habitats. What was the habitat: Area and substrate?

 

They are all on the same shrub.

 

Is the shrub in a city park, rural area, urban environment, residential area, or in wilderness, or on coast?

 

They are on a small shrub in Terra Nova Park in Richmond,
a few hundred yards from the river mouth/sea.
