'''''Punctelia tomentosula''''' is a species of foliose lichen in the family Parmeliaceae. Found in Peru, it was described as a new species in 1999 by Japanese lichenologist Syo Kurokawa.

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&nbsp;μm long. It has abundant pseudocyphellae and soralia on the thallus surface, and a brown lower surface.<ref name="Kurokawa 1999"/> ''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.&nbsp;tomentosula'' (5−6&nbsp;μm), and it does not have lecanoric acid in the medulla.<ref name="Canêz & Marcelli 2010"/>
