Peltigera koponenii is a species of foliose lichen in the family Peltigeraceae.[1] Found in Papua New Guinea, it was formally described as a new species in 2009 by Emmanuël Sérusiaux, Bernard Goffinet, Jolanta Miądlikowska, and Orvo Vitikainen. The type specimen was collected near Lake Wanba at an altitude of 2,400–2,500 m (7,900–8,200 ft), where it was found growing on a tree trunk in an open montane forest of Nothofagus and Pandanus. The species epithet honours Finnish bryologist Timo Koponen (fi), "who made large and well processed collections of Peltigera in Papua New Guinea".[2]
Description
This lichen species forms large [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] that can reach up to 20 cm (8 in) in diameter. The elongated [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] are typically sparingly divided, with rounded lobes measuring 0.5–0.8 mm wide at the extremities and a [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] margin. The upper surface is usually pale grey or slightly orange, sometimes bluish-grey, with an [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], whitish to pale brown [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] covering much of the surface. The lower surface is whitish to beige or pale brown, with a network of pale orange to brownish, distinctly raised [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]. Rhizines are abundant to extremely abundant, forming dense cushions or bushy masses that are usually long. Apothecia may be absent or abundant, growing almost vertically on raised, and [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] lobes. [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] have three septa, and are [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] and straight, with somewhat rounded ends; they measure 44–53 by 4–4.5 μm.[2]
Habitat and distribution
Peltigera koponenii is an epiphytic lichen species that grows on mossy trunks and branches in montane and subalpine forests. It can also be found overgrowing terrestrial moss cushions in the subalpine zone and on gravel by rivers or streams, as well as on artificial substrates such as hedges or garden fences in the montane forest zone. This species is also able to grow on tree fern trunks in deep valleys characterized by rare but acute frosts and irregular fires. Its altitudinal range is from 1,850 to 4,270 m (6,070 to 14,010 ft).[2]
