Peltigera canina (L.) Willd., syn.: Peltigera ulorrhiza (Flrke) Roum., Peltophora canina (L.) Clem, Pulmonaria terrestris Bory. Family: PeltigeraceaeEN: Dog Lichen, DE: Echte HundsflechteSlo.: pasji liajDat.: Oct. 12. 2021Lat.: 46.34956 Long.: 13.69225Code: Bot_1412/2021_4602Habitat: River bank, light mixed forest, at the base of a steep mountain, northeast aspect, locally almost flat terrain, calcareous ground, partly in shade, relatively cold and humid air place, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 6-8 deg C, elevations 525 m (1.720 feet), alpine phytogeographical region. Substratum: a medium size calcareous, moss overgrown boulder.Place: Lower Trenta valley, between villages Soa and Trenta, left bank of river Soa, next to Soa trail, near Trenta 46 farmhouse, East Julian Alps, Posoje, Slovenia EC Comments (pertain to pictures of Flicker album Peltigera canina): Dog lichens (genus Peltigera sp.) are large folios lichens, which often form extensive patches on ground, rocks or grassland. They grow mostly in woods but one can find them also on open places. Particularly the green ones are beautiful when moist and richly developed. To recognize them on genus level is not at all a problem. However, to determine them correctly (particularly gray-brown ones) on species level is sometimes quite a challenge, more so, if the thali are sterile that is without apothecia. The large difference in their appearance between being in dry or moist state are often striking. So, wrong determinations are quite common. Peltigera canina is a species, which is frequently confused with others, most often with very similar (and much more frequent) Peltigera membranacea. Peltigera canina can be distinguished from other species by irregular, shaggy, markedly bushy, confluent at the base, white rhizines and fuzzy tomentum on the upper side of the lobes. The underside has flattened, smooth and whitish veins (except sometimes in the middle of the thallus where they may be darker). Quite rare, roundish and very dark brown to black apothecia are also typical. Richly branched, woolly rhizines are most diagnostic (Ref.:1.) (see Fig.3a.). However, this rhizines form is not the only one present. Often several other shapes, including those common to Peltigera membranacea, are present or even dominant. Yet, no other Peltigera species has rhizines of this typical appearance than Peltigera canina.The lichen was one time used to treat rabies because the rhizines supposedly look like dogs' teeth (Ref.:4.).Ref.:(1) C.W.Smith, et all, The lichens of Great Britain and Ireland,The British Lichen Society (2009), p 667.(2) I.M.

Summary[
edit] Description: Peltigera degenii Gyelnik Image location: Mount Wilson, San Gabriel Mountains, Los Angeles Co., California, USA This was from the largest of three populations on the Mount Wilson Toll road, a mile or so above Henniger Flats. Growing on old moss-covered soil cut-bank in old oak forest on low-angle north-facing slope at around 3500 feet. This keys out clearly as
P. polydactylon in the Sonoran flora (absolutely no tomentum on surface, saddle-shaped brown apothecia, and obviously not
P. neopolydactyla). But the more I look at it the more convinced I am it looks significantly different from the
P. polydactylon I know from BC and NC. The veins, for example, are too well-developed and narrow; the interspaces are hardly “highly constrastive”. Apothecia are far too rare (only two or three in dozens of very well-developed thalli), and broader than I’m used to. Some regeneration lobules are present on margin edges and cracks, but this is not uncommon for polydactylon. Also the lobe tips are often conspicuously pruinose (see bottom photo), and the overall texture is less shiny than usual. Used references: Trevor Goward — dull surface, pale underside with narrow raised veins.

Peltigera horizontalis (Huds.) Baumg., syn.: Omphalia pseudoandrosacea (Bull.) J. Kickx f., Peltigera zopfii GyelnikFamily: PeltigeraceaeEN: Horizontal felt lichen, Horizontal Dog Lichen, DE: Waagrechte Blattflechte, Flachfrchtige Schildflechte SI: ravnodiskni pasji liajDat.: April 13. 2019Lat.: 46.359795 Long.: 13.709177Code: Bot_1180/2019_DSC4709 Picture file names: from Peltigera-horizontalis_raw_10 to Peltigera-horizontalis_raw_16.Habitat: Riparian forest, left bank of river Soa, flat terrain; moist ground and humid air, in shade, partly protected from direct rain by tree canopies; calcareous ground; average precipitations ~ 3.000 mm/year, average temperature 5-7 deg C, elevations 535 m (1755 feet), alpine phytogeographical region. Substratum: Mossy, heavily rotten stump of (most probably) Picea abies.Place: Lower Trenta valley, left bank of river Soa, near farmhouse Otokar, Trenta 4, East Julian Alps, Posoje, Slovenia EC. Comment: Lichens in genus Peltigera are often very beautiful. They have large foliose thalli with deep colors when moist. Sometimes they form very large patches on ground, rocks or wood, which may have more than 50 cm across. Particularly the green ones are very conspicuous. There are 15 species of this genus known in Slovenia (Ref.6). When thali are not well developed, or sterile, without apothecia, or dry their determination to species level may not be an easy task.Peltigera horizontalis is relatively rare lichen in Slovenia. Horizontal, roundish apothecia is the dominant distinguishing trait. However, white underside, interwoven with almost black mesh of veins and distinctive fasciculate (in tight bundles of fibers, particularly toward their ends) rhizines are also important in determination. The species is a good indicator of old forests.Ref.:(1) V. Wirth, Die Flechten Baden-Wrttembergs, Teil. 2., Ulmer (1995), p 681.(2)
