General:
Common Name: The Pelt Lichens. Echoes the genus name and describes the general resemblance of the species to various animal skins.
Small to large stratified foliose lichens, corticate above, noncorticate below, isidiate, sorediate or lobulate or not, cephalodiate or not, lobes loosely attached, short to subrotund, averaging to 1–3 (–4) cm wide, thin or thick. Upper surface greenish, greyish or brownish, smooth or somewhat roughened, naked or tomentose. Lower surface pale or dark, usually veined, bearing numerous rhizines, these short or long, slender or tufted. Medulla white. Photobiont green and/or blue-green.
Apothecia appressed on upper surface near margins, often saddle-shaped, disc brownish; spores 4-celled to multi-celled, ellipsoid or needlelike/acicular, colourless or brown at maturity, (2–) 8 per ascus.
Over soil and moss, occasionally over trees.
Notes: All but one of the 30 Peltigera species reported for North America are known to occur in B.C. Peltigera is a taxonomically rather difficult genus containing a number of species groups that are not yet satisfactorily elucidated. Chemistry is highly variable in this group; though thin-layer chromatography may help to identify some species, spot test reactions do not.
Contents:
Tenuiorin, various unknown substances (and gyrophoric acid).
