location
Lower Trenta valley, left bank of river Soča, near farmhouse Otokar, Trenta 4, East Julian Alps (Posočje, Slovenia)notes SI: ravnodiskni pasji lišaj - syn.: Omphalia pseudoandrosacea (Bull.) J. Kickx f., Peltigera zopfii Gyelnik - Habitat: Riparian forest, left bank of river Soča, 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. - 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-Württembergs, Teil. 2., Ulmer (1995), p 681.
