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: English: Dog lichen (Peltigera canina) This is a common lichen most often seen in the winter when damp conditions plump up its thalli - the grey leaf-like structures seen here. In drought they curl up like paper. It is to be found on rocks and dead wood, often growing in some profusion. It also occurs on lawns and grasslands where there is poor drainage. The brown capsules, or apothecia, seen here at the tips of some of the thalli contain the spores. The lichen's specific name, canina, (although it is now thought this common species should correctly be referred to as P. membranacea) relates to the resemblance of the white pointed spikes on the underside of the thallus to the fangs of a dog. Accordingly, by the doctrine of signatures, the lichen was once recommended as a cure for rabies. "In the words of John Lightfoot: The L. caninus has a disagreeable musty taste. Half an ounce of the leaves, dry'd and pulveriszed, and mixed with two drachms of powdered black pepper, compose the once-celebrated Pulvis antilyssus, formerly much recommended by the great Dr. Mead, for the cure of canine madness. This medicine was to be divided in four equal parts, one of which was to be taken by the patient every morning, fasting for four mornings successively, in half a pint of warm cow's milk; after which he was to use the cold bath every morning for a month. It is much to be lamented that the success of this medicine has not always answered the expectation. There are instances where the application has not prevented hydrophobia; and it even uncertain whether it has been at all instrumental in keeping off that disorder." Peltigera canina has also been used for a yellow dye. There is a species of moth (Thumatha senex)whose larvae feed upon it. Date: 20 February 2009. Source: From
