Physcia tribacioides soralia are “laminal, hemispherical”. In P. dubia they are labriform. In P. tribacia they are under scattered marginal protuberances.

at least in my understanding of it, the soredia is mainly distributed along the margins of lobes. I already created a new observation with a specimen that I believe to be Physcia tribacioides (see "MO70331"http://mushroomobserver.org/obs/70331). Please, give a look to it.
