Red-List of Endemic Galapagos Lichens (draft assessments):
This Red-List of Endemic Galapagos Lichens represents a first attempt to assess the threat status of Galapagos endemic lichen species. Currently all species of lichenized fungi considered endemic or questionably endemic are included . The assessment of only two species have so far officially been published by the IUCN: Acantholichen galapagoensis [assessed as Vulnerable B1ab(iii)+2ab(iii)], and Ramalina fragilis [assessed as Vulnerable A3c]. The assessments of all other species in this checklist are in progress.

native, questionably endem., according to Weber (1986 p. 478) the type of this species designated by Zahlbruckner (Ann. Mycol. 29:86. 1831) is deposited in Vienna (Floreana, Post Office Bay, Herre s.n.; W); Weber (1986) cites several specimens in COLO that he considers identical [L-40343 COLO 188855 (erroneously as L-30434); L-40198 COLO 189935; L-4038, COLO 188941; and L-40449 COLO 193411]; he emphasizes that he disagrees with Thompson (1963 p. 14) who, based on Zahlbruckner, Krypt. Exs. no. 3170, suggested that the species, contrary to the protologue, is not sorediate, but fertile; Weber points out that exsiccate specimens must not necessarily be considered identical with Zahlbruckner's type, further suggesting that the exsiccata might be a mixture of both P. insularis and P. mexicana; it is not clear, however, if Weber (1986 p. 478) has actually seen type material, when he annotated one specimen (L-40343, COLO 188855) as "p.p.; exactly matching the type", source: Thomson (1963), Weber (1966, 1986), Elix & McCarthy (1998)
