Usnea quasirigida is not too common in SW British Columbia, although it is sometimes frequent in small areas, particularly the Gulf Islands where it found as canopy debris in open Broadleaf Maple, Garry Oak, Arbutus(Madrone) and Douglas Fir forests. It can also be found on pilings along the lower Fraser River. The ciliate apothecia are usually present.

I first saw this at Bridal Veil Falls park in the Fraser River Valley on a field trip with Wolf Schofield back in the 1980’s. At that time, no one had seen it in the Bellingham area. Then we found it in a local park; then more and more; now it seems quite common throughout northwestern Washington State. I have seen it down into Skagit County but not further south. West of the Cascades only I think.
