Punctelia tomentosula Kurok. (1999)

The lichen has dense, dimorphous rhizines, a medulla that produces a rose colour with a C+ lichen spot test (caused by the presence of lecanoric acid), and short-filiform (threadlike) conidia that measure 7–9 μm long. It has abundant pseudocyphellae and soralia on the thallus surface, and a brown lower surface.^[1] Punctelia osorioi, found in South Brazil, is somewhat similar in appearance – particularly the dense rhizines. However, it does not have soralia, it has short, hook-like (unciform) conidia that are shorter than those in P. tomentosula (5−6 μm), and it does not have lecanoric acid in the medulla.^[2]
