Peltigera alkalicola

Ciri dan struktur

Peltigera alkalicola forms a small thallus, typically 1 – 5 cm in diameter, but usually smaller, about 1 – 2 cm. It has thick, rounded to elongate that are up to 1–2 cm long and 1 cm wide. The lobes often have rounded ends with upturned margins and may appear slightly crisped. The upper surface is , often slightly , and greyish-brown in colour. In contrast, the lower surface is generally white to pale brown, with that are the same colour or slightly darker and rhizines that are more abundant centrally, becoming shorter near the margins. This species develops isidia, which are small, dark brown to almost black outgrowths on the upper surface that are distinctly darker than the thallus surface. The species does not typically produce apothecia (sexual reproductive structures) or pycnidia (asexual reproductive structures), and no secondary metabolites (lichen products) have been detected by thin-layer chromatography. All standard chemical spot tests are negative.

Habitat dan peran ekologis

Peltigera alkalicola is found in high-elevation habitats, specifically in open, subalpine and alpine heathlands at elevations between 3940 and 4390 m. It is adapted to growing on trachybasaltic volcanic rock, a type of alkaline , and is often associated with sparse vegetation and bryophytes. At the time of its original publication, the species was known to occur only from a few locations on Mt Kilimanjaro and is considered rare. The collection sites for Peltigera alkalicola receive between 900 and 1100 mm of rainfall annually, maintain a relative humidity of 60 to 80%, and have an average annual temperature of 4 C. Initially discovered in Tanzania, genetic analysis suggests that Peltigera alkalicola may also be present in Alaska, USA, and Ningxia, China, indicating a wider distribution across diverse and extreme habitats. This distribution pattern highlights the species' preference for cold, montane regions and alkaline substrata.
