“Pertusaria paratuberculifera is superficially identical to the rarer P. valliculata, which has four spores per ascus compared to the 8 spores per ascus of P. paratuberculifera” (Harris and Ladd, 2005, p.162). Also, the ascospores of P. valliculata are ornamented, while those of P. paratuberculifera are smooth. “In the field this species [P. valliculata] is usually indistinguishable from the more common P. paratuberculifera, and must be examined microscopically to confirm the fewer, ornamented ascospores” (Harris and Ladd, p. 195).They also mention that P. valliculata is most common on Carya and Quercus, so that fits as well.
