Thank you very much for your efforts in researching web-links. Ecoport (the first link) 'looks' the most promising. The specimen I have is less circular and I have not observed an ostiole (but I am no expert, especially on mite galls).
I hope to make contact with Mr Gale, who is an expert on mite galls, in the near future. I am still searching for more specimens.
Thank you once again for your input and assistance.

Hello Scotty,
I do not have any pictures and I wonder if they are available anywhere on the
internet.
On some websites was information about gall causing mites etc on Myrica
species:
http://ecoport.org/ep?SearchType=pdb&PdbID=9416
and
https://kb.osu.edu/dspace/bitstream/1811/1819/1/V14N06_289.pdf
There is a fungal gall mentioned on Bog Myrtle on the site of the Nature Notes
from Skye:
